The intensive care unit (ICU) environment is often perceived to be hostile and frightening by patients due to unfamiliar surroundings coupled with presence of numerous personnel, monitors and other equipments as well as a loss of perception of time. Mechanical ventilation and multiple painful procedures that often need to be carried out in these critically(More)
BACKGROUND In patients undergoing craniotomy, skull pin insertion produces significant increases in heart rate (HR) and blood pressure. We investigated whether premedication with gabapentin would prevent or attenuate this increase. METHODS Forty-seven ASA I and II patients, 18 to 60 years, undergoing elective craniotomy for intracranial tumor surgery were(More)
BACKGROUND In patients undergoing craniotomy, the incidence of postoperative nausea and vomiting (PONV) is 55% to 70% and that of moderate to severe postoperative pain is 60% to 84%. We hypothesized that gabapentin plus dexamethasone would be superior, compared with placebo and dexamethasone in reducing the incidences of PONV and pain after craniotomy. (More)
BACKGROUND Mannitol and hypertonic saline (HS) are routinely used during craniotomy. Both increase myocardial preload and reduce afterload, and may improve cardiac output. It is not currently known whether this results in an improvement in the global myocardial function. Thus, the aim of this study was to compare the effects of a single equiosmolar bolus of(More)
BACKGROUND Mannitol increases intravascular volume by withdrawing water from the brain and causes significant changes in stroke volume, cardiac output (CO), systemic vascular resistance, central venous pressure (CVP), and blood pressure. No previous studies have demonstrated changes in left ventricular (LV) preload, afterload, and CO using transesophageal(More)
BACKGROUND Scalp infiltration with epinephrine-lidocaine solution in patients undergoing neurosurgery may result in transient but significant hypotension. We investigated whether premedication with alpha2-adrenoreceptor agonist clonidine, which also exhibits alpha1-adrenoreceptor mediated vasoconstriction, would prevent or attenuate this fall in mean(More)
