Endotracheal Anesthesia

Background. In recent years, various methods of combined anesthesia during abdominal surgery have been introduced into clinical practice.Aim. To demonstrate the possibilities of a combination of high prolonged spinal anesthesia and endotracheal anesthesia during abdominal surgery.Materials and methods. A clinical case of combined use of high prolonged spinal anesthesia and endotracheal anesthesia in a 48-year-old patient with a tumor in the right half of the ascending part of the right half of the colon is presented.Results. The patient received a puncture of the spinal space at a standard point and was installed a spinal catheter in the cranial direction for 3 cm. An isobaric solution of marcaine in the initial dose of 20 mg was injected into the catheter. The regulation of the development of the block was regulated by the inclination of the head end of the table by 60°. After that endotracheal anesthesia was performed on the basis of fentanyl and propofol. This combination allowed to expand the scope of surgical intervention, provided adequate pain relief intraoperatively and in the postoperative period, without the use of narcotic analgesics. With the appearance of signs of recovery of pain sensitivity, intraoperatively or in the postoperative period, re-introduction of the anesthetic into the spinal catheter was performed in half of the initial dose with liquor barbotage. In the early postoperative period, the patient was on strict bed rest with a head end of the bed raised at 30–45°. The method provides complete segmental blockade and muscle relaxation in the area of operation, stability of central hemodynamics during surgery and in the postoperative period.Conclusion. This type of anesthesia is more easily tolerated by patients, accompanied by early awakening and extubation, characterized by stability of central hemodynamics, reduced risk of complications, the possibility of prolonging anesthesia with lower doses of narcotic analgesics in the intraoperative period, providing high-quality anesthesia in the postoperative period without resorting to the use of narcotic analgesics.

Incomplete Ischemia

✓ The adverse effect of a minimal cerebral blood flow (CBF) in models of global ischemia has been noted by many investigators. One factor believed important in this situation is the level of blood glucose, since a continued supply of this metabolite results in increased tissue lactate, decreased brain pH, and increased cell damage. The authors have extended these observations to a model of focal incomplete ischemia. Brain pH was measured in fasted squirrel monkeys in regions of focal incomplete ischemia after transorbital occlusion of the middle cerebral artery (MCA). In both control and hyperglycemic animals, CBF was reduced to less than 30% of baseline. At 3 hours after MCA occlusion, brain pH in the control group was 6.66 ± 0.68 as compared to 6.27 ± 0.26 in the glucose-treated group. This difference was statistically significant by Student's unpaired t-test (p < 0.05). Thus, hyperglycemia results in decreased tissue pH in regions of focal incomplete cerebral ischemia in monkeys.
