The control of blood glucose in the critical diabetic patient: a neuro-fuzzy method.

Conventional algorithms for regulating insulin infusion rates in those critical diabetic patients submitted to parenteral glucose and insulin infusions do not allow to approach near normal blood glucose (BG) levels since traditional control systems are not fully effective in complex nonlinear systems as BG control is. Thus, we applied fuzzy logic principles and neural network techniques to modify intravenous insulin administration rates during glucose infusion. Forty critically ill, fasted diabetic subjects submitted to glucose and potassium infusion entered the study.

Perioperative management of diabetic subjects. Subcutaneous versus intravenous insulin administration during glucose-potassium infusion.

The purpose of this study was to validate methods for the perioperative management of diabetic patients that meet the prerequisites of simplicity, applicability in the absence of a diabetologist, and flexibility, to rapidly meet changing metabolic requirements. The patients were divided into two groups that were comparable for age, sex distribution, type of diabetes, and type of surgical procedures. The results show that intravenous insulin administration achieved better glycemic control during the intraoperative period, whereas it did not offer advantages over the subcutaneous route during the pre- and postoperative periods.

Dextran/aspirin versus heparin/dihydroergotamine in preventing thrombosis after hip fractures.

In a randomised trial we compared the effects of two different antithrombotic regimens on the incidence of venographically established deep venous thrombosis (DVT) in 83 patients undergoing surgery for fracture of the femoral neck. Group A received dextran 40 peroperatively plus 0.5 g aspirin a day beginning before operation and continuing for 10 days after.

[Anesthesia problems in children with cleft lip, maxilla and palate].

The technical and physiopathological problems associated with labiomaxillopalatine schisis in children are discussed. Personal experience, involving the choice of a type of anaesthesia based on the use of an analgesic (pentazocine), and the exclusion of halogenated anaesthetics in most cases, is reported. Stress is laid on the simplicity of the technique.

[Combination of althesin and fentanyl as an alternative anesthetic in burns].

The AA. examine the main metabolic and tissues physiopathologic effects after large burns. The same value advantages and disadvantages of anaesthesia treatments during excision and during medications on hard burns.
