What happens after discharge? Return hospital visits after ambulatory surgery.
The purpose of this study was to examine the frequency of return hospital visits after ambulatory surgery discharge and to identify any predictor variables for its occurrence. A retrospective review of hospital records for all patients returning to the same hospital within 30 days after ambulatory surgery was conducted. Data on return hospital visits that resulted in rehospitalization (as an inpatient or to the ambulatory surgery unit [ASU]) or treatment as an outpatient in the emergency room were recorded. ⋯ The increased likelihood of return visits after urology procedures warrants further evaluation. As patients with bleeding were most likely to return to the ER and discharged, more effective pre- and postprocedure patient education may further reduce this occurrence. Better informing patients regarding the prognosis of bleeding, and advising them of medical alternatives, could reduce inappropriate patient returns to the ER.

The efficacy of the "BURP" maneuver during a difficult laryngoscopy.
The displacement of the larynx in the three specific directions (a) posteriorly against the cervical vertebrae, (b) superiorly as possible, and (c) slightly laterally to the right have been reported and named the "BURP" maneuver. We evaluated the efficacy of the BURP maneuver in improving visualization of the larynx. Six hundred thirty patients without obvious malformation of the head and neck participated in this study. ⋯ The maneuver of Back and BURP significantly improved the laryngoscopic visualization from initial inspection. The BURP maneuver also significantly improved the visualization compared with the Back maneuver. We concluded that the BURP maneuver improved the visualization of the larynx more easily than simple back pressure on the larynx.

Immediate tracheal extubation after liver transplantation: experience of two transplant centers.
Early tracheal extubation has been safely performed after large operative procedures, questioning the need for routine postoperative ventilation. Because immediate postoperative tracheal extubation of liver transplantation patients has not been previously reported, we performed preliminary studies at two institutions to evaluate potential risk and cost benefit. At the University of Colorado (UC), extubation criteria were derived from the retrospective analysis of patients who were ventilated less than 8 h and experienced an intensive care unit stay less than 48 h in 1994. ⋯ Wider limits on age and severity of illness did not preclude successful extubation. Cost analysis at UC showed a significant reduction in intensive care unit services and associated cost for extubated patients. We conclude that immediate postoperative tracheal extubation of selected liver transplantation patients is safe and cost effective.

Recovery from doxacurium infusion administered to produce immobility for more than four days in pediatric patients in the intensive care unit.
Doxacurium was administered by titrated infusion to 14 pediatric patients for 4.7-12.3 days after laryngotracheal reconstruction to produce minimum spontaneous movement and less than five posttetanic movements of the first toe after stimulation of the posterior tibial nerve. Recovery was documented by stimulation of the ulnar nerve with 2 Hz for 2 s (train-of-four [TOF]) at intervals of 1 min and measurement of the ratio of the fourth to the first response (TOF ratio) at the adductor pollicis. ⋯ In six of the patients, weakness and decreased coordination were noted for a few days to weeks postoperatively. There were no complications related to impairment of upper airway function or ventilation in those patients who had recovery of neuromuscular transmission to the extent of TOF ratio equal to 1 prior to extubation or in those patients in whom weakness or lack of coordination was noted after tracheal extubation.

Parascalene block is a technique of blocking the brachial plexus at the lateral border of the anterior scalene muscle superior to the clavicle. The objective of this study was to define the position of the needle in parascalene block with relationship to the brachial plexus and the dome of the pleura, which is important in determining whether this technique minimizes the incidence of pneumothorax. In the first group, 10 patients scheduled for minor upper extremity surgery agreed to parascalene block, which was performed in the computed tomographic examination room. ⋯ The distances from the skin to the interscalene groove and the interscalene groove to the first rib at the level of the needle insertion or the marker in both groups were measured to be 17 +/- 4 mm and 15 +/- 3 mm, respectively. This study suggests that the level of the parascalene needle entry is superior to the dome of the pleura. At this level, the incidence of pneumothorax should be minimized.
