چکیده
Pulsatile ocular blood flow, intraocular pressure, systemic blood pressure, and heart rate was measured in two groups of 15 patients. One received lignocaine 1.5 mgtkg intravenously prior to induction. There was a significant increase in intraocular pressure after suxamethonium, which was not associated with any rise in ocular blood flow. Both the IOP and ocular blood flow increased significantly after tracheal intubation. A rise in ocular blood flow reflects the stress response associated with intubation. Lignocaine failed to attenuate either response. HEART RATE b/min

Effect of hypercapnea and hyperventilation on human intraocular pressure general anaesthesia following acetazolamide administration.
The changes in intraocular pressure due to blood pH, PCO2, and PO2 alterations induced by hyperventilation and hypercapnea in man undergoing routine general anaesthesia were studied. It was shown that hypercapnea produces elevation of intraocular pressure, while hyperventilation lowers it. Acetazolamide pretreatment did not alter these IOP responses to PCO2, PO2, and blood pH changes.
متن کاملEvaluation of the diurnal intraocular pressure fluctuations and blood pressure under dehydration due to fasting
Introduction: This study aimed to investigate the diurnal intraocular pressure fluctuations under dehydration conditions and the relationship between the intraocular pressure fluctuations and blood pressure. Methods: The intraocular pressures (IOP), body weights, as well as systolic and diastolic blood pressures (SBP, DBP) of 36 fasting healthy volunteers were recorded at 8:00 a.m. and 5:00 p.m...
متن کاملThe effect of low dose of ketamine on intraocular pressure in patients undergoing cataract surgery
Background: Cataract surgery is one of the most common surgeries in the world, especially in elderly patients, and often performed topically with sedative agents. Ketamine is one of the most commonly used agents and the effect of different doses on intraocular pressure is in dispute. The present study investigates the effect of a low dose of ketamine on intraocular pressure in patients undergoi...
متن کاملEffect on the intraocular pressure of hypotensive anaesthesia with intravenous trimetaphan.
The intraocular pressure was measured at 5-minute intervals with a Perkins applanation tonometer in 5 patients undergoing routine dacryocystorhinostomy under low-tension anaesthesia with a continuous intravenous infusion of trimetaphan (Arfonad), the systolic pressure being maintained at 66 mmHg. Twelve patients undergoing cataract surgery under the same premedication and anaesthesia but in who...
متن کاملEffect of corneal parameters on measurements using the pulsatile ocular blood flow tonograph and Goldmann applanation tonometer.
AIMS To investigate the effect of central corneal thickness and corneal curvature on intraocular pressure measurements using the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer, and to assess the agreement between the pulsatile ocular blood flow tonograph and the Goldmann applanation tonometer in intraocular pressure measurement. METHODS 479 subjects underwent int...
