ABSTRACT
It has been reported that pre-procedure ultrasonography rises the success rate of spinal anesthesia in obese patients. In this article, we performed spinal anesthesia for morbidly obese patient with pre-procedure ultrasonography. And recognizing the lumbar subcutaneous fat gradient in morbidly obese patient was the key to success. A cesarean section was scheduled for a primigravida in her 30 s with BMI 61 kg/m2. The lumbar spine was not palpable. Pre-procedure ultrasonography revealed lumbar subcutaneous tissue getting thicker caudally in the sagittal view. Considering this fact, we adjusted the puncture site and succeeded. Postoperative complications were not observed. The pre-procedure ultrasonography is effective even in morbidly obese patients. It is important to recognize the lumbar subcutaneous fat gradient, the so-called back fat slope, for spinal anesthesia in obese patients.
ABSTRACT
Hiccups are common reflexes and many treatment methods have been reported. Chlorpromazine is a known treatment option for hiccups, but its efficacy under general anesthesia remains unclear. We report the case of a patient with vagal schwannoma who developed hiccups while under general anesthesia. Muscle relaxants were not used because the patient was under neuromonitoring. The depth of anesthesia was deepened; however, the hiccups did not disappear. The hiccups were relieved by intravenous chlorpromazine administration (total; 5 mg), which allowed for surgery under neuromonitoring. This case indicates that chlorpromazine may be effective to treat hiccups under general anesthesia.
