[General surgical operations in patients with prior cardiac operations. Anesthetic and surgical risk].

The authors make an analysis of a group of 39 patients with cardiac interventions in their antecedents that later underwent general surgery. Of these 25 underwent planified surgery while 14 were operated as emergency cases. The surgery performed was of variable extension. Nine fatalities were recorded, representing 23,09%. Evaluation of the anesthetic and surgical risk factors revealed their dependence both on the myocardial hemodynamic efficiency (as determined by the previous heart surgery), and on the second intervention, emergencies presenting with a potentially increased risk factor. The authors stress the necessity to adapt the attitude of the anesthetist, as well as the intensive care, to particularities of the patient, and those determined by the second intervention.

[The Bain circuit. Theoretical aspects and clinical use].

After a concise theoretical presentation of the present stage of semiclosed circuits, the authors assess their personal experience in the use of the Bain system. Under controlled respiration, adminstration of a fresh flow of gases of 70 ml per Kg of body weight-1 per minute-1 (between 4,5 and 6 1 per minute-1) prevents reinchalation. By its characteristics, which include: on optimal control of PaCO2 by a simple variation of the flow of fresh gases, universality, economy, the Bain system has demonstrated its utility in the anesthetics practice.

[Use of naloxone (Narcar) in anesthesiological practice].

The antagonising effect induced on respiratory depression by fentanyl and morphine was studied in two lots of patients. Recovery from respiratory depression was general and evident. A correlation was found between the amount of naloxone and the amount of the major analgesic used. Beside respiratory depression naloxone has also partially antagonised in some cases the analgesic effects of fentanyl and morphine.

[Scheduled reinterventions in the treatment of acute peritonitis].

UNLABELLED: This is a clinical series of 83 cases, admitted in the Surgical Department of Fundeni Hospital between 1988-1996 of severe acute peritonitis in which scheduled reoperations (at least one planned reoperation at 24-48 hours after the first operation) were performed. The main criteria for scheduled reoperations were; unresolved source of contamination, acute peritonitis older than 48 hours and the presence of multiple system organ failures. 63 cases (76%) were postoperative peritonitis. 203 planned reoperations were performed (minimum: 1, maximum: 10, mean: 2,4 reoperations per patient). In 12 cases (14,4%) a laparotomy "on demand" was necessary after the scheduled reoperations were stopped. The source of peritonitis was resolved in 61 cases (73,5%) and unresolved in 22 cases (26,5%). In 9 cases (10%) specific complications of the method (hemorrhages, fistulas) were encountered. The global mortality was 65,06%, with 55,73% mortality when the source of peritonitis was resolved and 90,9% mortality when the source was not resolved. CONCLUSION: scheduled reoperations have to be reserved for the most severe cases of acute peritonitis in which the mortality after the "classical" methods of treatment is extremely high.

[Total vascular exclusion in liver surgery].

II cases of major hepatic resections under total vascular isolation (TVA) are presented: 4 women and 7 men, age between 17 and 70 years (mean 39.6 years). In another 2 cases the method was abandoned because the patients did not tolerate the vena cava clamping. The main indication for TVA were large tumors located near the suprahepatic veins opening into the vena cava. The diagnosis in the 11 cases was: hepatocellular carcinoma--3 cases, cholangiocarcinoma--1 case, colo-rectal metastasis--1 case, hemangioma--3 cases, hamartoma--2 cases, diffuse suppuration of the right lobe--1 case. The warm ischemia time was between 25 and 50 min (mean: 36.8 min). There were no intraoperative complications. The mean quantity of transfused blood was 450 ml. Postoperatively two patients bled and were reoperated. Both subsequently developed liver failure and died and in both cases microscopy found histologic lesions of chronic hepatitis. The mortality was then 18.1%. Six patients (54.5%) developed postoperative complications. Worth noting are 2 cases of transient liver failure, both in patients with cancer. The ICU stay was between 2 and 14 days (mean 7.1) and the whole postoperative hospitalization was between 11 and 46 days (mean: 16).

[Repeat hepatic resections].

Five cases of iterative liver resections are presented, out of a total of 150 hepatectomies performed between 1.01.1995-1.01.1998. The resections were carried out for recurrent adenoma (one case), cholangiocarcinoma (two cases), hepatocellular carcinoma (one case), colo-rectal cancer metastasis (one case). Only cases with at least one major hepatic resection were included. Re-resections were more difficult than the primary resection due, first of all, to the modified vascular anatomy. Intraoperative ultrasound permitted localization of intrahepatic recurrences. Iterative liver resection appears to be the best therapeutical choice for patients with recurrent liver tumors.
