Evaluation of the Effects of Diabetes on Preoperative and Postoperative Patients' Status with Blood Glucose Level, Arterial Blood Gas, and Alveolar-arterial O2 Tension Difference / 대한마취과학회지

BACKGROUND: Diabetes mellitus is the most common endocrinopathy encountered in the perioperative period. It is a disease of glucose dysregulation and carbohydrate intolerance frequently associated with acute and long-term systemic consequences, which may significantly impact morbidity and mortality This study was performed to evaluate the effects of diabetes on perioperative patients' status. METHODS: Thirty adults patients, 15 control and 15 diabetic patients, who underwent upper abdominal surgery with general anesthesia were included in this study. We investigated blood glucose levels, arterial blood gas, blood chemistry values, and calculated alveolar- arterial oxygen tension differences. Statistical analyses were performed using the Fisher's exact test, unpaired t-test, paired t-test, and repeated measure ANOVA. Data are expressed as mean +/- SD. RESULTS: The blood glucose levels were significantly higher in the diabetic group than the control group during operation. The postoperative calcium and albumin concentrations were significantly lower in the diabetic patients than the control patients. The alveolar-arterial oxygen tension differences were significantly increased in the diabetic group compared with the control group during operation. CONCLUSIONS: This study demonstrated that the blood glucose levels were significantly increased in the diabetic patients compared with the control patients during operation. This finding suggests that blood glucose levels should be monitored and controlled within an adequate range in diabetic patients perioperatively.

Study of Spinal Sensory Block Height with 0.5% Heavy Bupivacaine in Elderly Patients / 대한마취과학회지

BACKGORUND: The relationship among age, height and sensory block height in elderly patients who underwent spinal anesthesia using 0.5% heavy bupivacaine were studied. METHODS: Ninety-seven elderly patients, 65 years of age or older, who were scheduled for spinal anesthesia were divided into four groups. 8 mg of 0.5% heavy bupivacaine was injected in patients who were shorter than 160 cm, and 9 mg was injected in patients who were taller than 160 cm. Then they were further divided into a 65 74 year old group and an older than 75 year old group, and the area of sensory block was compared by the age and height. RESULTS: Sensory block height was not significantly different between the 65 74 year old group and the older than 75 year old group. Height did not correlate with sensory block height in all groups, and the distribution shapes showed variable patterns. CONCLUSiONS: The effect of age and height on the spinal sensory block height in elderly patients is small.

Acute Pulmonary Edema Following Esophagoscopy - A case report / 대한마취과학회지

There are many predisposing factors for acute pulmonary edema, Pulmonary edema in well recognized complication of acute airway obstruction, especially in small children, but rarely seen in adults. We present a case of noncardiogenic pulmonary edema that developed in adult following removal of endotracheal intubation after esophagoscopy, The sequence of events suggest that laryngospasm precipitated the development of the pulmonary edema in this patient.
