[General anesthesia during short operations in patients using the herbal psychogenic stimulant CAT (Catha edulis)].

The specific features of general anesthesia during short inpatient operations were performed in 85 patients who were regular CAT users owing to their national habits. According to the herbal psychogenic stimulant CAT dependence, the patients were divided into 3 groups. The findings indicate that propofol (2 mg/kg) in combination with isoflurane and premedication as diatepam (0.1-0.15 mg/kg) and fentanyl (1 mg/kg) is the anesthesia of choice in all group patients. Ketamine in combination with isoflurane may be used in the controls and Group 1 patients with mild CAT dependence. In patients with moderate and severe CAT dependence, ketamine should be considered to be contraindicated due to the development of adverse psychomotor and somatic reactions requiring monitoring and drug correction in an intensive care unit. The results of the study have been introduced into practice on choosing the modes of anesthesia at the Revolution Hospital, Republic of Yemen.

Cerebral blood flow (CBF) and central hemodynamics (CH) have been studied during anesthesia and after surgery in patients with tumours located in brain hemispheres. CBF and CH were determined by radiography. GOBA, diazepam and sodium thiopental were used for anesthesia. It has been shown that GOBA fails to normalize CBF both during and after surgery, diazepam normalizes blood flow in both brain hemispheres. Sodium thiopental leads to further CBF depression up to critical level in the affected hemisphere with parallel blood flow ingress in the intact brain hemisphere. It is concluded that the use of diazepam is advisable for anesthesia during surgery for tumours located in brain hemispheres.

Retrospective analysis of 9262 formalized case histories has been made to compile a protocol of anesthesia. Each blank contains 223 items describing the patient and is intended for retrospective computer analysis of the information. Phases of the complications onset have been established and a working classification of complications has been suggested. Organization measures, which reduced the frequency of complications by 2.4% have been elaborated. The factors that increase the frequency of anesthesia-induced complications are reviewed.
