Résumé

Irregular or unexpected antibodies are alloantibodies against serum or red blood cells after previous exposure to transfusion. When encountered in critical condition, however, risk of ongoing complication is not entirely predictable. Rapid transfusion of safe blood is thus, crucial not to compromise further procedure. A 78-year-old ASA IV man presented with Hunt-Hess grade IV subarachnoid hemorrhage with huge temporal bleeds. While in operating room, his blood pressure dropped when the dura was opened. Meanwhile, routine screening of blood typing repeatedly denoted Rh+O with irregular antibodies. Soon, compatible cross-matched blood was infused with 37 degrees C normal saline 200 ml at a rate of 4-5 ml/kg/hr. There was no laboratory evidence of hemolytic transfusion reaction. Postoperatively, BUN and creatinine increased slightly, but urination and respiration were unremarkable.

Résumé

BACKGROUND: We studied the hemodynamic changes induced by pneumoperitoneum and a reversed Trendelenburg in elderly patients with increased cardiac risk (ASA class III; n = 30; age 70.8 +/- 4.9 years, mean +/- SD) and compared the results with elderly patients at normal risk (ASA class II; n = 30; age 69.2 +/- 4.1 years) during laparoscopic cholecystectomy. METHODS: The transesophageal Doppler monitor was performed after induction of general anesthesia (pre-incision), after onset of pneumoperitoneum (insufflation), after head-up (20degrees) and a left lateral tilt (15degrees) (reversed Trendelenburg) and after deflation and horizontal position (desufflation). Mean arterial pressure (MAP), heart rate, cardiac index (CI) and systemic vascular resistance (SVR) were measured, respectively. RESULTS: Induction of pneumoperitoneum and head-up tilt in patients with cardiac risk resulted significantly in a decrease in CI and an increase in SVR compared with patients with normal risk (P < 0.05), and that remained until deflation, but no interval changes in MAP and heart rate. The CI, MAP and heart rate decreased and SVR increased significantly in patients with cardiac risk compared with patients with normal risk before incision (P < 0.05). No complications occurred. The results indicate that pneumoperitoneum and a reversed Trendelenburg are associated with significant but relatively benign hemodynamic changes. CONCLUSIONS: Anesthesia for laparoscopic cholecystectomy in elderly patients with increased cardiac risk should be performed with an adequate hemodynamic monitoring.

Résumé

Esmolol is a cardioselective beta-blocker with a very rapid onset of action and a short half-life. Labetalol is a combined alpha- and beta-adrenoceptor blocking agent. It is a nonselective antagonist at beta-adrenoceptors and a competitive antagonist of postsynaptic alpha 1-adrenoceptors. A 51 year old female patient was transferred to the operating room for performing spinal fusion under general anesthesia. She had no operation and medication history. The initial heart rate was 150 beats/min. Despite administering several bolus injections of esmolol, the heart rate was not decreased to under 130 beats/min. But the heart rate was decreased to 100 beats/min after the administration of labetalol 5 mg and this rate was maintained without an additional injection. The vital signs were stable until the operation was finished and the patient recovered uneventfully in the recovery room. The postoperative laboratory findings revealed that she had hyperthyroidism. We report here on an anesthetic experience of effective labetalol treatment for esmolol-resistant tachycardia in a patient who was under general anesthesia.
