Randomized Controlled Trial Comparative Study Clinical TrialInterscalene brachial plexus block is superior to subacromial bursa block after arthroscopic shoulder surgery.
Arthroscopic shoulder surgery is often associated with severe postoperative pain. The results concerning subacromial bursa blockade (SUB) as a method of pain relief have been contradictory. We hypothesized that a SUB and interscalene brachial plexus block (ISB) would similarly reduce early postoperative pain and the need for oxycodone as compared to placebo (PLA). ⋯ After arthroscopic shoulder surgery SUB has a minor effect only on postoperative analgesia, whereas an ISB with low-dose ropivacaine effectively relieves early postoperative pain and reduces the need for opioids.

Randomized Controlled Trial Clinical TrialExtubation after breathing trials with automatic tube compensation, T-tube, or pressure support ventilation.
Automatic tube compensation (ATC) is a new option to compensate for the pressure drop across the endotracheal or tracheostomy tube (ETT), especially during ventilator-assisted spontaneous breathing. While several benefits of this mode have so far been documented, ATC has not yet been used to predict whether the ETT could be safely removed at the end of weaning, from mechanical ventilation. ⋯ After the inclusion of 90 patients (30 per group) we did not observe significant differences between the modes. Twelve patients failed the initial weaning trial. However, half of the patients who appeared to fail the spontaneous breathing trial on the T-tube, PSV, or both, were successfully extubated after a succeeding trial with ATC. Extubation was thus withheld from four and three of these patients while breathing with PSV or the T-tube, respectively, but to any patient breathing with ATC. It seems that ATC can be used as an alternative mode during the final phase of weaning from mechanical ventilation. Furthermore, this study may promote a larger multicenter trial on weaning with ATC compared with standard modes.

The incidence of withholding and withdrawing life support from the critically ill has increased in recent years. The aim of this study was to assess the degree of consistency between the weight assigned by intensivists to different determinants and their relation to end-of-life decisions, and to evaluate the current concepts in withholding or withdrawing intensive care in Nordic countries. ⋯ No generally accepted grounds for end-of-life decisions could be detected among Nordic intensivists. In addition, the current concept of management after decision to withdraw therapy varies markedly. This study has implications in further assessment of the individual decision-making process and the uniformity of actions after withdrawal decisions.

Randomized Controlled Trial Comparative Study Clinical TrialA comparative study on the analgesic effect of tramadol, tramadol plus magnesium, and tramadol plus ketamine for postoperative pain management after major abdominal surgery.
We tested whether, after major abdominal surgery, the addition of magnesium or ketamine to tramadol for intravenous (IV) patient-controlled analgesia (PCA) improved analgesia and lowered pain scores, compared to a PCA containing only tramadol. ⋯ Adding magnesium or ketamine to tramadol improved analgesia and patient comfort and decreased the amount of tramadol required for postoperative pain management after major abdominal surgery.

Since the first version saw the light of day in 1991 the Guidelines have occupied a central position in the Norwegian practice of anesthesia. This document comprises part of the quality management documents held in the departments of anesthesia in Norwegian hospitals. If departments of anesthesia are unable to adhere to certain specific points in the Guidelines, it is recommended that this should be documented in writing. ⋯ The Guidelines should be adhered to in medical emergencies as far as possible. The Guidelines must not be allowed to prevent the execution of immediate and lifesaving measures. The Guidelines should be revised at regular intervals so that it is up-to-date with current legislation and medical and technological developments and practice.
