Pneumothorax is a rare complication of pneumoperitoneum. We report a case of spontaneous bilateral pneumothorax during laparoscopic cholecystectomy. The history, pathogenesis, and therapeutic options of this unusual occurrence are discussed. Because laparoscopic operations have become increasingly popular in recent years, we call attention to this rare but potentially life-threatening complication.

Plasma cholinesterase activity was periodically measured in bank blood. Of the initial plasma cholinesterase activity 87% was retained after 21 days of storage at 4 C in citrate-phosphate-dextrose solution. In addition, plasma frozen for 7 weeks at -70 C showed no decrease in enzyme activity. No difference could be demonstrated in the stability of the enzyme related to whether the blood was stored in citrate-phosphate-dextrose or in acid-citrate-dextrose solution. Bank blood transfusion prior to or during succinylcholine administration should not significantly alter the duration of action of succinylcholine, and would probably be effective in the management of prolonged apnea resulting from a deficiency of this enzyme.

The football field, an ideal setting for research in trauma by radiotelemetry, has allowed collection of data on man's response to impact. The physiologic response adds a new dimension to the measurement of impact tolerance. The present study has demonstrated the protective response of the athlete and explains how he is able to dissipate forty times more kinetic energy than his helmet is capable of absorbing.

Intraovular pressure was measured in 20 patients undergoing anesthesia for electroshock therapy. Compared to control values, determined on the day before electroshock therapy, statistically significant elevations of intraocular pressure followed the post-electroshock therapy convulsions and were still significant 5 minutes later, but not of sufficient magnitude or duration to cause concern.
