ABSTRACT: Ninety-four patients undergoing elective outpatient third molar extraction were recruited into a double-blind, randomized, prospective trial comparing mivacurium (group M) with succinylcholine (Group S) for conditions for endotracheal intubation and the occurrence of postoperative myalgia. <snip> The incidence of postoperative myalgia was 9.5% in group M and 26% in group S but this was not statistically significant (P = 0.09).
MB: There was some myalgia after mivacurium but difference was not statistically significant.!!!

CONCLUSION: The results suggest that for definitive preemptive analgesia, blockade of opioid and N-methyl-d-aspartate receptors is necessary for upper abdominal surgery such as gastrectomy; singly, either treatment provided significant, but not definitive, postsurgical pain relief. Epidural morphine may affect the spinal cord segmentally, whereas intravenous ketamine may block brain stem sensitization via the vagus nerve during upper abdominal surgery.

ABSTRACT: BACKGROUND: During experimental cardiac arrest, continuous insufflation of air or oxygen (CIO) through microcannulas inserted into the inner wall of a modified intubation tube and generating a permanent positive intrathoracic pressure, combined with external cardiac massage, has previously been shown to be as effective as intermittent positive pressure ventilation (IPPV). METHODS: After basic cardiorespiratory resuscitation, the adult patients who experienced nontraumatic, out-of-hospital cardiac arrest with asystole, were randomized to two groups: an IPPV group tracheally intubated with a standard tube and ventilated with standard IPPV and a CIO group for whom a modified tube was inserted, and in which CIO at a flow rate of 15 l/min replaced IPPV (the tube was left open to atmosphere). Both groups underwent active cardiac compression-decompression with a device. Resuscitation was continued for a maximum of 30 min. Blood gas analysis was performed as soon as stable spontaneous cardiac activity was restored, and a second blood gas analysis was performed at admission to the hospital. RESULTS: The two groups of patients (47 in the IPPV and 48 in the CIO group) were comparable. The percentages of patients who underwent successful resuscitation (stable cardiac activity; 21.3 in the IPPV group and 27.1% in the CIO group) and the time necessary for successful resuscitation (11.8 +/- 1.8 and 12.8 +/- 1.9 min) were also comparable. The blood gas analysis performed after resuscitation (8 patients in the IPPV and 10 in the CIO group) did not show significant differences. The arterial blood gases performed after admission to the hospital and ventilation using a transport ventilator (seven patients in the IPPV group and six in the CIO group) showed that the partial pressure of arterial carbon dioxide (PaCO2) was significantly lower in the CIO group (35.7 +/- 2.1 compared with 72.7 +/- 7.4 mmHg), whereas the pH and the partial pressure of arterial oxygen (PaO2) were significantly higher (all P < 0.05). CONCLUSIONS: Continuous insufflation of air or oxygen alone through a multichannel open tube was as effective as IPPV during out-of-hospital cardiac arrest. A significantly greater elimination of carbon dioxide and a better level of oxygenation in the group previously treated with CIO probably reflected better lung mechanics.

PUBLICATION TYPE: CLINICAL TRIAL; JOURNAL ARTICLE; RANDOMIZED CONTROLLED TRIAL
ABSTRACT: BACKGROUND: Despite extensive training of citizens of Seattle in cardiopulmonary resuscitation (CPR), bystanders do not perform CPR in almost half of witnessed cardiac arrests. Instructions in chest compression plus mouth-to-mouth ventilation given by dispatchers over the telephone can require 2.4 minutes. In experimental studies, chest compression alone is associated with survival rates similar to those with chest compression plus mouth-to-mouth ventilation. We conducted a randomized study to compare CPR by chest compression alone with CPR by chest compression plus mouth-to-mouth ventilation. METHODS: The setting of the trial was an urban, fire-department-based, emergency-medical-care system with central dispatching. In a randomized manner, telephone dispatchers gave bystanders at the scene of apparent cardiac arrest instructions in either chest compression alone or chest compression plus mouth-to-mouth ventilation. The primary end point was survival to hospital discharge. RESULTS: Data were analyzed for 241 patients randomly assigned to receive chest compression alone and 279 assigned to chest compression plus mouth-to-mouth ventilation. Complete instructions were delivered in 62 percent of episodes for the group receiving chest compression plus mouth-to-mouth ventilation and 81 percent of episodes for the group receiving chest compression alone (P=0.005). Instructions for compression required 1.4 minutes less to complete than instructions for compression plus mouth-to-mouth ventilation. Survival to hospital discharge was better among patients assigned to chest compression alone than among those assigned to chest compression plus mouth-to-mouth ventilation (14.6 percent vs. 10.4 percent), but the difference was not statistically significant (P=0.18). CONCLUSIONS: The outcome after CPR with chest compression alone is similar to that after chest compression with mouth-to-mouth ventilation, and chest compression alone may be the preferred approach for bystanders inexperienced in CPR.
MB: This experiment was done in the US.

PUBLICATION TYPE: BIOGRAPHY; HISTORICAL ARTICLE; JOURNAL ARTICLE
ABSTRACT: Robert H. Goetz performed the first successful clinical coronary artery bypass operation on May 2, 1960. He used a nonsuture technique to connect the right internal thoracic artery to the coronary artery by means of a modified Payr's cannula made of tantalum. The patency of the anastomosis was demonstrated angiographically and the patient remained free of angina pectoris for 1 year. It was an important and brave step forward, a step that was far ahead of its time. Unfortunately, his pioneering work was not appreciated and fell into oblivion.
MB: I think the first vein graft was in Argentina in 1968---after I had wondered why it was not being done.

ABSTRACT: We report the case of a 3-year-old boy who underwent correction of transposition of the great arteries who developed burns from use of a patient warming device. His repair had been delayed because he was from a developing country, and he was offered surgery as part of a humanitarian effort. Postoperatively he was noted to have second- and third-degree burns from use of a Bair Hugger (Augustine Medical, Eden Prairie, MN) warming system after cardiopulmonary bypass.

CONCLUSIONS: Dexamethasone facilitates early tracheal extubation and is associated with a lower incidence of early postoperative fever and new-onset atrial fibrillation. Apart from a treatable decreased glucose tolerance, dexamethasone treatment was not shown to affect morbidity or mortality significantly.

(T)he counteracting effect of acetylsalicylic acid [ASA] on the augmentation of prostacyclin synthesis by ACE inhibitors could result in a potential reduction of the beneficial effects of the angiotensin-converting enzyme (ACE) inhibitor's and could be of great importance. This article reviews reports from large clinical trials pertaining to this issue and relates their findings to the currently available theoretical bases for support of the counteracting effect of ASA on augmentation of prostacyclin synthesis by ACE inhibitors. The clinical implications of such an interaction are discussed.

CONCLUSIONS: Contrary to previous suggestions persistent smoking does not substantially reduce the age specific onset rate of Alzheimer's disease or of dementia in general. If anything, it might increase rather than decrease the rate, but any net effect on severe dementia cannot be large in either direction.

ABSTRACT: OBJECTIVE: We hypothesized that patients with septic shock who achieve negative fluid balance (< or =-500 mL) on any day in the first 3 days of management are more likely to survive than those who do not. DESIGN: Retrospective chart review. PATIENTS: Thirty-six patients admitted with the diagnosis of septic shock. SETTING: Twelve-bed medical ICU of a 300-bed community teaching hospital. METHODS: Medical records of 36 patients admitted to our medical ICU over a 21-month period were examined. Patients with septic shock who required dialysis prior to hospitalization were not included. A number of demographic and physiologic variables were extracted from the medical records. Admission APACHE (acute physiology and chronic health evaluation) II and daily sequential organ failure assessment (SOFA) scores were computed from the extracted data. Variables were compared between survivors and nonsurvivors and in patients who did vs those who did not achieve negative (< or = 500 mL) fluid balance in > or = 1 day of the first 3 days of management. Survival risk ratios (RRs) were used as the measure of association between negative fluid balance and survival. RRs were adjusted for age, APACHE II scores, SOFA scores on the first and third days, and the need for mechanical ventilation, by stratified analyses. RESULTS: Patients ranged in age from 16 to 85 years with a mean (+/- SE) age of 67.4 +/- 3.3 years. The mean admission APACHE II score was 25.4 +/- 1.4, and the day 1 SOFA score was 9.0 +/- 0.8. Twenty patients did not survive; nonsurvivors had higher mean APACHE II scores than survivors (29.8 vs 20.4, respectively) and higher first day SOFA scores than survivors (10.8 vs 6.9, respectively), and they were more likely to require vasopressors and mechanical ventilation compared to patients who survived. Whereas all 11 patients who achieved a negative balance of > 500 mL on > or = 1 of the first 3 days of treatment survived, only 5 of 25 patient who failed to achieve a negative fluid balance of > 500 mL by the third day of treatment survived (RR, 5.0; 95% CI, 2.3 to 10.9; p = 0.00001). At least 1 day of net negative fluid balance in the first 3 days of treatment strongly predicted survival across the strata of age, APACHE II scores, first- and third-day SOFA scores, the need for mechanical ventilation, and creatinine levels measured at admission. CONCLUSION: These results suggest that at least 1 day of negative fluid balance (< or = -500 mL) achieved by the third day of treatment may be a good independent predictor of survival in patients with septic shock. These findings suggest the hypothesis "that negative fluid balance achieved in any of the first 3 days of septic shock portends a good prognosis," for a larger prospective cohort study.
MB: They suggest that one should not even think of giving diuretics to fix sepsis but I am sure that will not stop a new fashion.

ABSTRACT: STUDY OBJECTIVES: To determine how often serum lidocaine concentrations (SLC) fall into the potentially toxic range (> 5 mg/L) in asthmatics undergoing research bronchoscopy, and to determine whether subject or procedure characteristics are associated with higher SLC. DESIGN: Prospective, observational study. SETTING: Academic research center. CONCLUSIONS: An average total dose of 600 mg (8.2 mg/kg) of lidocaine appears to be safe in mild to moderate asthmatics undergoing research bronchoscopy.
MB: A student was killed in New York a while ago having some experimental bronchooscopic thing done.

In conclusion, of all patients receiving intrathecal opioids, the large majority of men and all women developed hypogonadotropic hypogonadism, about 15% developed central hypocorticism, and about 15% developed GH deficiency. These findings suggest that further investigations are required to determine the need for systematic endocrine work-up in these patients and the necessity for substitutive therapy.

ABSTRACT: Exposure to ionizing radiation, changing levels of iodine nutrition, and increased pathologic diagnosis of clinically unimportant thyroid neoplasia have all been proposed as explanations for a worldwide rise in the incidence of thyroid carcinoma (TC) over the past 6 decades. Tasmania is geographically an area of endemic iodine deficiency. In this report, we describe the spectrum of TC in a population averaging 450,000 persons during a 21-yr period that spans the communities transition from iodine sufficiency to iodine deficiency after discontinuation of universal iodine prophylaxis in the mid 1980s. The Tasmanian Cancer Register was used to ascertain all cases of TC diagnosed in Tasmania between 1978 and 1998. Histopathological and demographic data were reviewed. A total of 289 cases of TC were identified. Papillary TC (PTC), follicular TC, medullary TC, and other species accounted for 62%, 23%, 4%, and 11% of cases, respectively. The age standardized incidence rate for total TC increased from 2.45 to 5.33 per 100,000 for females and 0.75 to 1.76 per 100,000 for males between 1978 and 1984 and 1992 and 1998, respectively. A rise in the incidence of PTC by 4.5-fold (P < 0.05) in females and 2.1-fold in males (not significant) was the dominant change over this period. In parallel, the proportion of follicular TC relative to PTC fell from 0.35 to 0.17 during these years (P < 0.05). The rise in PTC incidence was, in part, due to an increase in the occurrence of tumors 1cm or less in diameter. Nonetheless, a 3-fold rise in incidence of larger lesions was also observed during the study period. Forty-three (24%) PTC cases had multifocal disease, 17 (40%) of whom had bilateral tumors. Familial (autosomal dominant) PTC was identified in nine (5%) total PTC cases. Prior studies have linked iodine prophylaxis to a rise in the proportion of differentiated TC, particularly PTC. Our data suggest a complex relationship between iodine nutrition and thyroid tumorigenesis. Factors such as a long latency between changes in iodine nutrition and thyroid tumorigenesis, a dose threshold for the effect of iodine nutrition on thyroid tumorigenesis, and an interaction between iodine nutrition and thyroidal sensitivity to ionizing radiation may all play a role.
MB: Did they really stop giving iodine in Tasi? Look at the full text for the changes which must have been politically generated. There is now iodine deficiency in Tasmania where there had been sufficiency.

ABSTRACT: This review assesses the extent to which sevoflurane fulfills the requirements of the ideal inhalational agent for use in neuroanesthetic practice. Sevoflurane's pharmacokinetic profile is outlined. Data from animal and human studies are used to discuss its effects on cerebral hemodynamics, central nervous system monitoring, and cardiovascular parameters. Where possible, sevoflurane is compared with isoflurane, currently considered the inhalational agent of choice in neuroanesthesia. Sevoflurane's potential for toxicity is reviewed.

ABSTRACT: Since its introduction into clinical practice in 1988, the laryngeal mask airway (LMA) has been used as an alternative device to achieve and maintain control of the airway during anesthetics. The LMA has been used primarily in patients undergoing peripheral procedures in the supine position. The authors describe its use in an open intracranial neurosurgical procedure for a patient with a space occupying lesion. To our knowledge, this is the first such description in the literature.

ABSTRACT: CONTEXT: Pharmacoeconomic analyses are being used increasingly as the basis for reimbursement of the costs of new drugs. Reports of these analyses are often published in peer-reviewed journals. However, the analyses are complex and difficult to evaluate. OBJECTIVE: To describe the nature of problems encountered in the evaluation and interpretation of pharmacoeconomic analyses used as a basis for reimbursement decisions. DATA SOURCES: All major submissions to the Department of Health and Aged Care (DHAC) by the pharmaceutical industry for funding made under the Australian Pharmaceutical Benefits Scheme. Specifically, the DHAC's database of submissions that were received between January 1994 and December 1997 were reviewed. STUDY SELECTION: Of a total of 326 submissions, 218 had serious problems of interpretation and were included in the analysis. The nature of the serious problems reviewed were classified as estimates of comparative clinical efficacy, comparator issues, modeling issues, and calculation errors. DATA EXTRACTION: All submissions in the DHAC's database were reviewed and data were extracted if both the DHAC evaluators and technical subcommittee considered problems to have a significant bearing on the decisions of the parent committee. DATA SYNTHESIS: Of a total of 326 submissions, 218 (67%) had significant problems and 31 had more than 1 problem. Of the 249 problems identified, 154 (62%) related to uncertainty in the estimates of comparative clinical efficacy, and 71 (28.5%) related to modeling issues, which included clinical assumptions or cost estimates, used in the construction of the economic models. There were 15 instances of disagreement over the choice of comparator, and serious calculation errors were found on 9 occasions. Overall, 159 problems (64%) were considered to be avoidable. CONCLUSIONS: Significant problems were identified in these pharmacoeconomic analyses. The intensive evaluation process used in the Australian Pharmaceutical Benefits Scheme allowed for identification and correction of pharmacoecomomic analysis problems, but the resources that are required may be beyond the capacity of many organizations, including peer-reviewed journals.

CONCLUSIONS: A need exists for collaborative education of physicians and nurses in performing, obtaining, and interpreting information from the use of pulmonary artery catheters. This effort should be led by professional societies, in collaboration with federal agencies, with the purpose of developing and disseminating standardized educational programs. Areas given high priority for clinical trials were pulmonary artery catheter use in persistent/refractory congestive heart failure, acute respiratory distress syndrome, severe sepsis and septic shock, and low-risk coronary artery bypass graft surgery.

ABSTRACT: CONTEXT: Hemodynamic monitoring of patients with a pulmonary artery catheter is controversial because there are few data confirming its effectiveness, and patient and intensive care unit (ICU) organizational factors associated with its use are unknown. OBJECTIVE: To determine pulmonary artery catheter use in relationship to type of ICU organization and staffing, and patient characteristics, including severity of illness and insurance coverage. DESIGN, SETTING, AND PATIENTS: Retrospective database study of 10,217 nonoperative patients who received treatment at 34 medical, mixed medical and surgical, and surgical ICUs at 27 hospitals during 1998 (patients were enrolled in Project IMPACT). MAIN OUTCOME MEASURES: Pulmonary artery catheter use based on severity of illness measured by the Simplified Acute Physiology Score, resuscitation status at ICU admission, and ICU organizational variables, including type, size, and model. RESULTS: A pulmonary artery catheter was used for 831 patients (8.1%) in the ICU. In multivariate analysis adjusted for severity of illness, age, diagnosis, and do-not-resuscitate status, full-time ICU physician staffing was associated with a two-thirds reduction in the probability of catheter use (odds ratio [OR], 0.36; 95% confidence interval [CI], 0.28-0.45). Higher catheter use was associated with white race (OR, 1.38; 95% CI, 1.10-1.72) and private insurance coverage (OR, 1.33; 95% CI, 1.10-1.60). Admission to a surgical ICU was associated with a 2-fold increase in probability of catheter use (OR, 2.17; 95% CI, 1.70-2.76) compared with either medical or mixed medical and surgical ICUs. CONCLUSION: Organizational characteristics of ICUs, insurance reimbursement, and race, as well as clinical variables, are associated with variation in practice patterns regarding pulmonary artery catheter use. Understanding such influences, combined with studies measuring clinical and economic outcomes, can contribute to the development of policies for the rational use of pulmonary artery catheters.

ABSTRACT: BACKGROUND: Conous infusions of sedative drugs in the intensive care unit may prolong the duration of mechanical ventilation, prolong the length of stay in the intensive care unit and the hospital, impede efforts to perform daily neurologic examinations, and increase the need for tests to assess alterations in mental status. Whether regular interruption of such infusions might accelerate recovery is not known. METHODS: We conducted a randomized, controlled trial involving 128 adult patients who were receiving mechanical ventilation and continuous infusions of sedative drugs in a medical intensive care unit. In the intervention group, the sedative infusions were interrupted until the patients were awake, on a daily basis; in the control group, the infusions were interrupted only at the discretion of the clinicians in the intensive care unit. RESULTS: The median duration of mechanical ventilation was 4.9 days in the intervention group, as compared with 7.3 days in the control group (P=0.004), and the median length of stay in the intensive care unit was 6.4 days as compared with 9.9 days, respectively (P=0.02). Six of the patients in the intervention group (9 percent) underwent diagnostic testing to assess changes in mental status, as compared with 16 of the patients in the control group (27 percent, P=0.02). Complications (e.g., removal of the endotracheal tube by the patient) occurred in three of the patients in the intervention group (4 percent) and four of the patients in the control group (7 percent, P=0.88). CONCLUSIONS: In patients who are receiving mechanical ventilation, daily interruption of sedative-drug infusions decreases the duration of mechanical ventilation and the length of stay in the intensive care unit.
MB: The sedation is for the observers not the patient. When I was solely responsible for a series of ventilated patients before we had an ICU ward between 1964 and 1972 although I was prepared to sedate &/or paralyse them, I never did. (Note that I did not say---'I never had to'. Giving drugs to a patient is the result of a decision by the doctor. There is no compulsive necessity).

ABSTRACT: BACKGROUND: Traditional approaches to mechanical ventilation use tidal volumes of 10 to 15 ml per kilogram of body weight and may cause stretch-induced lung injury in patients with acute lung injury and the acute respiratory distress syndrome. We therefore conducted a trial to determine whether ventilation with lower tidal volumes would improve the clinical outcomes in these patients. METHODS: Patients with acute lung injury and the acute respiratory distress syndrome were enrolled in a multicenter, randomized trial. The trial compared traditional ventilation treatment, which involved an initial tidal volume of 12 ml per kilogram of predicted body weight and an airway pressure measured after a 0.5-second pause at the end of inspiration (plateau pressure) of 50 cm of water or less, with ventilation with a lower tidal volume, which involved an initial tidal volume of 6 ml per kilogram of predicted body weight and a plateau pressure of 30 cm of water or less. The primary outcomes were death before a patient was discharged home and was breathing without assistance and the number of days without ventilator use from day 1 to day 28. RESULTS: The trial was stopped after the enrollment of 861 patients because mortality was lower in the group treated with lower tidal volumes than in the group treated with traditional tidal volumes (31.0 percent vs. 39.8 percent, P=0.007), and the number of days without ventilator use during the first 28 days after randomization was greater in this group (mean [+/-SD], 12+/-11 vs. 10+/-11; P=0.007). The mean tidal volumes on days 1 to 3 were 6.2+/-0.8 and 11.8+/-0.8 ml per kilogram of predicted body weight (P<0.001), respectively, and the mean plateau pressures were 25+/-6 and 33+/-8 cm of water (P<0.001), respectively. CONCLUSIONS: In patients with acute lung injury and the acute respiratory distress syndrome, mechanical ventilation with a lower tidal volume than is traditionally used results in decreased mortality and increases the number of days without ventilator use.

MB: A big review. They noticed decreased mortalities over short periods but do not really entertain the idea that the 'syndrome' may be iatrogenic or that the treatments are detrimental. From my historical perspective the incidence is a fraction of what it was 25-30 years ago.

CONCLUSION: Rectal MXT compares favorably to other methods of nonintravenous sedation for CT scanning of stable pediatric ED patients in terms of rapidity of onset and reliability but does cause a significant amount of transient respiratory depression. Its use requires careful monitoring of oxygen saturation and should be used only in a setting where physicians skilled in airway management are present. If these requirements are met, it may be a good choice for the relatively noninvasive sedation of pediatric ED patients undergoing painless but anxiety-provoking procedures.methohexital, pediatric procedure sedation, rectal administration, computerized tomography imaging.

ARTICLE TITLE: Early use of non-invasive ventilation for acute exacerbations of chronic obstructive pulmonary disease on general respiratory wards: a multicentre randomised controlled trial.

ABSTRACT: BACKGROUND: Within the intensive-care unit, non-invasive ventilation (NIV) can prevent the need for intubation and the mortality associated with severe episodes of chronic obstructive pulmonary disease (COPD). The aim of this study was to find whether the introduction of NIV, early after the admission on a general respiratory ward, was effective at reducing the need for intubation and the mortality associated with acute exacerbations of COPD. METHODS: We did a prospective multicentre randomised controlled study comparing NIV with standard therapy in patients with mild to moderate acidosis. NIV was administered on the ward with a simple non-invasive ventilator and a standardised predefined protocol. Patients were recruited from 14 UK hospitals over 22 months. FINDINGS: 236 patients were recruited, 118 received standard therapy alone and 118 additional NIV. The two groups had similar characteristics at enrolment. The use of NIV significantly reduced the need for intubation as defined by the failure criteria. 32/118 (27%) of the standard group failed compared with 18/118 (15%) of the NIV group (p=0.02). In-hospital mortality was also reduced by NIV, 24/118 (20%) died in the standard group compared with 12/118 (10%) in the NIV group (p=0.05). In both groups pH, PaCO2, and respiratory rate improved at 4 h (p<0.01). However, NIV led to a more rapid improvement in pH in the first hour (p=0.02) and a greater fall in respiratory rate at 4 h (p=0.035). The duration of breathlessness was also reduced by NIV (p=0.025). INTERPRETATION: The early use of NIV for mildly and moderately acidotic patients with COPD in the general ward setting leads to more rapid improvement of physiological variables, a reduction in the need for invasive mechanical ventilation (with objective criteria), and a reduction in in-hospital mortality.

ABSTRACT: Under normal circumstances, the coagulation system is balanced in favour of anticoagulation. Thrombin is the key effector enzyme of the clotting cascade. Antagonists of vitamin K inhibit a vitamin-K-dependent post-translational modification of several coagulation proteins, which is required for these proteins to attain a phospholipid-binding conformation. Heparin stimulates the activity of antithrombin, a serine-protease inhibitor. Analysis of knock-out mice has shown the relative importance of the coagulation factors in vivo. Gene therapy may soon be a therapeutic option for inherited deficiencies of factors VIII and IX.
