Dantrolene (2.45 mg/kg body weight, range 2 to 4) was administered iv in eight heat stroke (HS) patients and compared with a control group of 12 patients of similar age, weight, and temperature range (41.9 degrees to 44 degrees C). Body surface cooling was conducted in air conditioned rooms at temperatures of 18 degrees to 23 degrees C. Mean cooling time in(More)
PURPOSE To compare the efficacy of tramadol and morphine for intra- and postoperative analgesia in patients undergoing laparoscopic cholecystectomy. METHODS In a prospective, randomized, double-blind study 100 patients were allocated randomly into two groups. Ten minutes before induction of anaesthesia, patients in group 1 received 100 mg tramadol and(More)
During pilgrimage season (Hajj) in Saudi Arabia 34 patients with heat stroke (HS) were centrally cannulated to assess their state of hydration and fluid requirement during cooling period. Central venous pressure (C.V.P.) measurements indicated that most victims of heat stroke had normal C.V.P. on arrival at heat stroke centres and may not be fluid depleted.(More)
This study examined the theoretical knowledge and practical skills of different medical profession personnel and medical students in Basic Cardiac Life Support (BCLS). Two hundred twenty-four candidates who attended a BCLS course were tested in their theoretical knowledge of BCLS with 15 multiple choice questions (MCQs) as a pre-test. The same questions(More)
Study of admissions to the surgical intensive care unit (SICU) at King Khalid University Hospital in Riyadh was carried out from 1982 to 1987. There were 1149 surgical admissions, of whom 96 patients died (mortality rate 8.3%). Eighty-six patients died of multisystem and organ failure (MSOF). Sepsis appeared to be the ultimate cause of death in 54 patients(More)
In a randomized, double-blind study we have examined the analgesic efficacy of caudal administration of midazolam, bupivacaine, or a mixture of both drugs in 45 children, undergoing inguinal herniotomy. They were allocated randomly into three groups (n = 15 in each) to receive a caudal injection of either 0.25% bupivacaine 1 with or without(More)
Fifty children undergoing inguinal herniotomy were allocated randomly to three groups to receive a caudal injection of either 0.25% bupivacaine 1 ml kg-1 with or without ketamine 0.5 mg kg-1 or ketamine 0.5 mg kg-1 with normal saline 1 ml kg-1. There was no significant difference in quality of pain relief, postoperative behaviour or analgesic requirements(More)
BACKGROUND Dexmedetomidine is a potent new alpha-2 adrenoceptor agonist with an alpha-2 to alpha- ratio more than 7 times that of clonidine. Its potent sedative, analgesic and sympatholytic effects blunt the cardiovascular responses (hypertension, tachycardia) without unexpected toxicity. Many reports confirmed its pharmacological properties if given by(More)
The relative potencies of propofol and thiopentone were assessed using different indicators of induction of anaesthesia: abolition of the response to verbal commands and eyelash stimulation. Log-probit dose-response curves for these end-points were determined 30, 60 and 90 s after induction in 96 unpremedicated ASA group I patients. For propofol, ED50(More)
OBJECTIVE Gynecological admissions to the surgical intensive care unit vary from the obstetrical cases. Pregnant women are of prime age and can tolerate the pregnancy and delivery well. There are certain rare conditions or complications, which make the pregnant women's life pass through a critical time. These are dealt with in a high dependency area, which(More)
