Electrocardiographic changes after laparoscopic cholecystectomy.

AIM: To determine whether ECG changes observed after laparoscopic cholecystectomy could be correlated with procedure characteristics. MATERIAL AND METHODS. We studied prospectively 500 patients who underwent laparoscopic cholecystectomy for documented gallstones and prior history of cardiovascular disease, volume of carbon dioxide insufflated in the peritoneal cavity, duration of the procedure and intra-abdominal pressure created. RESULTS: We found that 9 (1.8%) patients developed LV strain, 2 (0.4%) patients--atrial fibrillation, 2 (0.4%) patients--tachyarrhythmia in the presence of AF, 1 (0.2%) patient--RBBB and 1 (0.2%) patient--myocardial ischemia with ST depression regarding these ECG leads. Statistical analysis of the data was performed using multifactorial logistic regression analysis. These changes were not correlated to the above referred procedure characteristics. CONCLUSION: We conclude that ECG changes are frequent events after laparoscopic cholecystectomy (3%) but are not correlated to prior history of cardiovascular disease, the duration of the procedure, the volume of carbon dioxide insufflated and the intra-abdominal pressure.

The influence of corticosteroids on ileostomy discharge of patients operated for ulcerative colitis.

The ileostomy output and electrolyte loss was studied in 23 patients undergoing operation for ulcerative colitis, to determine corticosteroid influence. Ten patients did not use corticosteroids and 13 patients received postoperatively 400 mg hydrocortisone intravenously for 4 to 5 days followed by 90 mg prednisone per os thereafter. Ileostomy volume and electrolyte concentration and total loss were measured on the 4th and 8th postoperative days. Patients on corticosteroids presented with a reduction of volume lost from the ileostomy (P less than 0.001), lower sodium concentration and total loss (P less than 0.00001), higher potassium concentration (P less than 0.00001) with similar total loss (P is not significant) and higher calcium concentration (P less than 0.00001) but lower total loss (P less than 0.05). It is concluded that corticosteroid administration influences significantly both volume and electrolyte loss due to the ileostomy discharge in patients operated for ulcerative colitis, suggesting a need for careful maintenance of fluid and electrolyte balance in the early postoperative period.

The effect of preoperative treatment with cimetidine on postoperative wound sepsis.

The results of preoperative treatment of uncomplicated duodenal ulcer patients with Cimetidine are presented. Cimetidine given preoperatively increases the pH of gastric aspirates and alters the bacterial flora of the stomach at the time of operation, resulting in an increased incidence of postoperative wound sepsis. Discontinuing Cimetidine 2 days before surgery is a safe step against the risk wound sepsis.
