A case of thoraco-abdominal rigidity leading to respiratory failure is described in the post-operative period in an elderly patient who received a moderate dose of fentanyl. This was successfully reversed by naloxone. The mechanisms possibly implicated in this accident are discussed.

Two alternative anesthetic techniques for use during carotid endarterectomy were studied in a series of 424 procedures. A total of 248 were performed in patients under general anesthesia and 176 patients received regional block anesthesia. Perioperative instability of blood pressure was noted in 108 patients. ⋯ The 1 month operative mortality for the entire carotid series was 1.2% (5/424). There were three stroke-related deaths. In addition, two nonfatal major strokes and two minor strokes occurred in patients who received general anesthesia vs one nonfatal major stroke in a patient who received regional block anesthesia.

Prolonged anastomotic and needle hole bleeding from synthetic vascular prostheses is a common surgical problem in heparinized patients and in the patient with a coagulopathy. The relative effectiveness of various hemostatic agents has not previously been determined by controlled comparisons. In this study 6 mm polytetrafluoroethylene (PTFE) vascular prostheses were used to perform carotid-carotid and femorofemoral bypasses in eight heparinized dogs. ⋯ Although application of isobutyl 2-cyanoacrylate resulted in the shortest MTH in each experimental group, the reported inflammatory response that it induces and its possible carcinogenicity limits its availability for clinical use. Application of fibrin adhesive prepared from single-donor hepatitis-screened plasma resulted in a significantly shorter MTH in each experimental group when compared with oxidized regenerated cellulose. We recommend clinical use of fibrin adhesive to control needle hole and anastomotic bleeding from PTFE vascular prostheses.

Cholinesterase deficiency is a relatively rare condition. However, if unrecognized, this condition can be potentially fatal. The authors present a case report of cholinesterase deficiency and a review of the literature. Discussion of the preoperative evaluation and preventive measures is also included.

Examination of swallowing after total laryngectomy using manofluorography.
Investigation of postlaryngectomy dysphagia is usually limited to the standard barium swallow. Manofluorography (mano, manometry; fluoro, videofluoroscopy; graphy, picture) is a new technique that permits analysis of simultaneous manometry and videofluoroscopy of deglutition. Manofluorography provides more detailed analysis of the swallowing dynamics during the pharyngeal stage of deglutition than either barium studies or manometry used alone. ⋯ The laryngectomy patients compensated by using increased lingual propulsion, whereas the patients with tongue impairment and total laryngectomy could not. This emphasizes the importance of the tongue in bolus propulsion in the pharynx. Other postoperative changes in swallowing are discussed.
