A Comparative Study Of Positive Pressure Ventilation Via Laryngeal Mask Airway And Endotracheal Tube, A Idrees, F A. Khan Oct 2000

A Comparative Study Of Positive Pressure Ventilation Via Laryngeal Mask Airway And Endotracheal Tube, A Idrees, F A. Khan

Department of Anaesthesia

Objective: To investigate the use of Laryngeal Mask Airway (LMA) and its comparison with the endotracheal tube for positive pressure ventilation.SETTING: A tertiary care teaching hospital.Methods: Fifty adult ASA I and II patients undergoing peripheral limb surgery were randomly allocated to 2 groups for LMA or endotracheal tube insertion. A standardized anaesthetic technique was used. The groups were then compared regarding haemodynamic changes on insertion as well as removal of LMA and ETT and any complications that occurred were noted.Results: The haemodynamic response to insertion was significantly attenuated (p < 0.05) in LMA group as compared to ETT group. The cardiovascular response to extubation was not significantly different between the groups. A higher incidence of coughing and mild hypoxaemia at extubation was noted in ETT group as compared to LMA group (p < 0.05) and blood was detected in 4 cases after LMA removal.CONCLUSION: It is concluded that the use of LMA during positive pressure ventilation is safe in selected cases. There is an attenuated haemodynamic response to insertion of LMA as compared to endotracheal tube which will be beneficial in certain patients e.g., those with ischaemic heart disease, vascular disease and hypertensives.

The Accuracy Of Nitrous Oxide Passive Dosimeters As Compared With An Infra-Red Spectrographic Reference Method, Susan Allen May 1999

The Accuracy Of Nitrous Oxide Passive Dosimeters As Compared With An Infra-Red Spectrographic Reference Method, Susan Allen

Community & Environmental Health Theses & Dissertations

Nitrous oxide is a gas often used in dental, surgical and veterinary operations as an anesthetic agent. Employees stationed in proximity of fugitive gas emissions may potentially suffer adverse health effects from chronic exposure to this agent. Passive dosimeters can be worn in the breathing zone of potentially affected personnel during exposure periods, then later analyzed to quantify nitrous oxide exposure. This study sought to establish the accuracy of several commercially available passive monitoring devices for nitrous oxide by comparison against an infra-red spectrophotometric reference method.

Experience With Larangeal Mask Airway In Pakistani Patients, F A. Khan, M A. Afzal, R S. Kamal Dec 1996

Experience With Larangeal Mask Airway In Pakistani Patients, F A. Khan, M A. Afzal, R S. Kamal

Department of Anaesthesia

One hundred and thirty seven adult patients undergoing peripheral surgery were studied regarding ease of larangeal mask airway (LMA) insertion, airway maintenance during surgery and complication encountered during insertion, maintenance and in the postoperative period. In a majority (84%) of patients, the airway was positioned correctly at the first attempt, 3% patients had mild laryngospasm at insertion and in 85% a good airway was obtained. No airway related problems were encountered intraoperatively. Two percent patients had laryngospasm on removal of LMA. Postoperatively, the complaint of sore throat and uvular trauma was seen in 4% cases.

Evaluation Of Oral Midazolam As Pre-Medication In Day Care Surgery In Adult Pakistani Patients, N Ahmed, F A. Khan Sep 1995

Evaluation Of Oral Midazolam As Pre-Medication In Day Care Surgery In Adult Pakistani Patients, N Ahmed, F A. Khan

Department of Anaesthesia

A placebo controlled randomized double blind study was designed to assess the suitability of oral Midazolam as a premedication in day care surgery in adult Pakistani patients. Fifty ASA I and II patients aged between 20-60 years received either Midazolam 7.5 mg or a placebo approximately one hour prior to surgery. Midazolam 7.5 mg produced significant anxiolysis and sedation (p < 0.001) in comparison to placebo after one hour of premedication. There was a significant difference (p < 0.001) in the mean heart rate and blood pressure in both groups after 1 hour of premedication with a lesser rise in blood pressure and heart rate in the Midazolam group. Psychomotor performance assessed by 'n' deletion test was impaired by Midazolam (p < 0.001) and recall of pictures revealed differences (p < 0.05) in the groups at one hour after premedication. However, at four hours after surgery there were no differences in both groups. These findings indicate that rapidly acting oral Midazolam in doses of 7.5 mg provided safe and effective premedication in terms of anxiolysis, sedation, amnesia and psychomotor performance and is suitable for day surgery.

The Effects Of Suxamethonium And Pancuronium On The Haemodynamic Response To Endotracheal Intubation, F A. Khan, R S. Kamal Mar 1991

The Effects Of Suxamethonium And Pancuronium On The Haemodynamic Response To Endotracheal Intubation, F A. Khan, R S. Kamal

Department of Anaesthesia

The pharmacological effects of suxamethonium and pancuronium on the cardiovascular system may vary and therefore alter the haemodynamic response to intubation. The arterial blood pressure, the heart rate and the rate pressure product were measured as parameters of haemodynamic change in forty adult ASA. I and II patients undergoing laryngoscopy and endotracheal intubation in a randomised controlled study. The patients were induced with either thiopentone/suxamethonium (Group A) or thiopentone/pancuronium (Group B). There was no significant difference between the groups on comparison of systolic and diastolic blood pressure changes. Pancuronium, however, caused a significantly higher rise in the heart rate after …
