مقایسه تغییرات همودینامیک در بیماران الکتیو جراحی با تجویز دو پیش داروی بیهوشی دی هیدروبنزپریدول و پرومتازین

Effects of preanaesthetic medication are as follows: 1) Promotion of mental and emotional relaxation. 2) Inhibition of nausea and vomiting after surgery. 3) Stability of haemodynamic response. We performed 105 patients, randomized, single blind clinical trial, preanaesthetic drugs, promethazine and droperidol: A comparison of haemodynamic response for patients in elective surgery at imam hospital. 105 patients were divided in three groups. Promethazine group 35 patients, dropetidol group 35 patients and normal saline group 35 patients. Systolic and diastolic blood pressure and pulse rate were recorded before and after intramuscular injection. Patients of promethazine and droperidol groups responded with decreasing in blood pressure and pulse rat lower than normal saline. But haemodynamic response did not show any difference between two groups (promethazine and droperidol).
