[Acute ischemia of the hand as a complication of radial artery catheterization. Apropos of 2 cases following abdominal sarcoma surgery]. / Isquemia aguda de la mano como complicación de la canalización de la arteria radial. A propósito de dos casos tras cirugía de sarcoma abdominal.

Arterial catheterization is a simple technique that yields great benefits, such as continuous monitoring of arterial pressure and the possibility of taking repeated samples for analysis. However, it is not free of complications, the main ones being limb ischemia and gas embolism. To reduce the risk of complications, guidelines for insertion and maintenance of arterial catheters have been established. We report two cases of acute hand ischemia secondary to arterial catheterization. Both patients were undergoing surgery for sarcoma-type abdominal cancer and developed acute ischemia of the hand lasting several hours. The predisposing factor in both cases was the existence of a highly advanced sarcoma-type abdominal tumor, probably related to a state of hypercoagulability.

Anesthetic support in synchronous liver and kidney transplantation.

BACKGROUND/AIMS: We performed a retrospective evaluation of 11 patients in the final stages of hepatic disease with chronic kidney failure, in whom simultaneous double liver-kidney transplantation was performed. METHODOLOGY: In the immediate pre-, intra- and postoperative periods, we assessed metabolic, hemodynamic and coagulation parameters; bicarbonate, calcium and inotropic drug requirements; the incidences during reperfusion of the graft; the surgical technique employed; the need for hemodialysis and/or ultrafiltration; and the survival rate of the patients. RESULTS: Of the 11 cases studied, four patients needed hemodialysis, while only one patient needed ultrafiltration; three patients required both techniques, and no dialysis or ultrafiltration was performed in three patients. The following surgical techniques were employed: Total clamping of the inferior vena cava using an external venovenous bypass in two cases; total clamping of the inferior vena cava without an external venovenous bypass in three cases; and partial clamping of the inferior vena cava with preservation of the retrohepatic cava in six cases. The results showed one death in the first postoperative month and two deaths in the course of subsequent follow-up. The survival rate was 72.7%. CONCLUSIONS: The use of conventional intraoperative hemodialysis and/or ultrafiltration is feasible, useful and achieves good results in patients undergoing double liver-kidney transplantation. Partial clamping of the inferior vena cava at the anhepatic stage appears to reduce the need for ultrafiltration. There is no increase in perioperative mortality in patients who underwent liver transplantation while conserving their renal function.

[Usefulness of isoflurane in anesthesia in elective cesarean section]. / Utilidad del isofluorano en la anestesia de la cesárea electiva.

A series of 25 patients undergoing iterative cesarean section under general anesthesia received isoflurane at 0.75% together with a mixture of O2 and N2O at 50% for anesthetic maintenance. The inhalant agent was withdrawn when closing fascia. There was no case of regaining of consciousness during the operations. Uterine contraction was acceptable as evaluated by the surgeon at the end of the operation. Mean hematocrit value was 31.43 (SD 1.27) at 6 hours of operation. Fetal arterial gasometric values and Apgar score at 5 and 10 minutes fell within acceptable limits.
