Case ReportsAnaphylaxis to pantoprazole during general anesthesia.
The most frequent causes of anaphylaxis during anesthesia are neuromuscular blocking agents, antibiotics, and latex. Proton pump inhibitors (PPI) are widely used during major surgery for the prevention of stress ulcers, but cases of perioperative anaphylactic reactions to these have rarely been reported. ⋯ After resuscitation, the patient recovered without any sequelae. Six months after the surgery, a skin test was positive to pantoprazole.

The usefulness of an earphone-type infrared tympanic thermometer during cardiac surgery with cardiopulmonary bypass: clinical report.
We evaluated the usefulness of a novel earphone-type infrared tympanic thermometer (IRT) during cardiac surgery with cardiopulmonary bypass. Tympanic membrane temperature (T(Tym)) was monitored using the IRT inserted into the right ear canal of 12 adult patients (ASA III) who had been scheduled for elective cardiac surgery with cardiopulmonary bypass under general anesthesia. Rectum (T(Rec)) and nasopharyngeal temperatures (T(Naso)) were also monitored, and all temperatures were recorded at 5-min intervals during cardiopulmonary bypass. ⋯ Significant correlations were seen between T(Tym) and T(Naso) (r = 0.971, P < 0.001), and T(Tym) and T(Rec) (r = 0.759, P < 0.001). A Bland-Altman plot showed that average temperature of T (Tym) was 0.06°C above T(Naso) (±0.66°C, 2 SD) and 0.12°C below T(Rec) (±1.78°C, 2 SD). We conclude that an earphone-type IRT is noninvasive and hygienic and could continuously evaluate selective cerebral temperature during cardiopulmonary bypass in adults.

The effect of target-controlled infusion of low-dose ketamine on heat pain and temporal summation threshold.
We investigated the heat pain threshold (HPT) and temporal summation threshold (TST) before and after target-controlled infusion (TCI) of ketamine with an effect-site concentration (Ce) of 30 and 60 ng/ml. ⋯ TCI of ketamine with a Ce of 30 and 60 ng/ml increased TST but not HPT.
