Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed Feb 2006

Laparoscopic Surgery In Children--Anaesthetic Considerations, Aliya Ahmed

Department of Anaesthesia

Laparoscopic surgery has several advantages over conventional surgery for the patient. An increasing number of diagnostic and surgical procedures are being done laparoscopic not only in adults but also in paediatrics patients. In addition to the routine anaesthetic considerations for any surgical patient, the choice of the anaesthetic technique in patients undergoing laparoscopic procedures should consider the patient's underlying cardio respiratory functions induced by the pneumoperitoneum and carbon dioxide [CO2] insufflations. This article describes the physiological alterations induced by laparoscopic procedures in children and the anaesthetic implications of laparoscopic in the paediatric patient population.


The Role Of Prophylactic Intra-Aortic Balloon Pump Counterpulsation (Iabp) In Emergency Non-Cardiac Surgery, Khalid Samad, Fauzia Anis Khan Jan 2006

The Role Of Prophylactic Intra-Aortic Balloon Pump Counterpulsation (Iabp) In Emergency Non-Cardiac Surgery, Khalid Samad, Fauzia Anis Khan

Department of Anaesthesia

Patients with recent myocardial infarction (MI), congestive heart failure, severe angina, or uncorrected multivessel coronary artery disease are at increased risk of cardiac complications after urgent major non-cardiac surgery. Although invasive haemodynamic monitoring and preoperative optimization of cardiac status may lead to some reduction in the rate of perioperative cardiac events, the mortality from such events still remains high. The use of an intra-aortic balloon pump (IABP) may play a role in such patients by improving the function of the injured heart. We report our experience with the use of perioperative IABP in a patient with unstable angina and recent …

Apache Ii Score As A Predictor Of Length Of Stay And Outcome In Our Icus, Shahla Siddiqui, Saad Ahmed, Roshan Manasia Jun 2005

Apache Ii Score As A Predictor Of Length Of Stay And Outcome In Our Icus, Shahla Siddiqui, Saad Ahmed, Roshan Manasia

Department of Anaesthesia

The APACHE II (acute physiology and chronic health evaluation) is used widely for predicting probability of hospital mortality and length of stay in the ICU. APACHE II forms were available to all ICU residents within 24 hours of admission, and a score was assigned to them. Based on our results the APACHE II score has reliably predicted an outcome of the least amount of length of stay (LOS) in the ICU as well as a 100% probability of being shifted out of the ICU for a score of < 10 (according to international benchmarks). This reliable scoring system can be used for predicting mortality and length of stay and therefore, resource allocation, antibiotic use and ethical decisions regarding counseling families about end of life decisions--all within 24 hours of admissions.

The objective of our study was to evaluate the unanticipated hospital admission rate from the Surgical Day Care (SDC) unit of our university affiliated teaching hospital and to analyze the reasons for admission. A review of all unanticipated admissions over a one-year period was done. The admission rate was calculated and the reasons for admission were analysed. The overall admission rate was 4.93%. Most of the admissions were ordered by the surgeons (97%). The main reasons for admission were patient observation indicated …


Perioperative Anaesthetic Management Of A Patient With Relapsed Aplastic Anaemia, Aliya Ahmed, Abdul Monem Jun 2005

Perioperative Anaesthetic Management Of A Patient With Relapsed Aplastic Anaemia, Aliya Ahmed, Abdul Monem

Department of Anaesthesia

Aplastic anaemia occurs due to failure of blood cell production by bone marrow. All blood cell counts are low. Untreated patients may die within one year mainly due to uncontrolled infection due to neutropenia. Anaemia and thrombocytopenia cause troublesome symptoms and necessitate frequent red cell and platelets transfusions. Surgery poses a very high risk for these patients because of the several complications that can occur in the perioperative period. In this paper we report on a patient with relapsed aplastic anaemia who was optimized preoperatively and underwent a total abdominal hysterectomy under general anaesthesia.

Midazolam And Thiopentone Co-Induction: Looking For Improvement In Quality Of Anaesthesia, M A. Khan, F A. Khan Nov 2003

Midazolam And Thiopentone Co-Induction: Looking For Improvement In Quality Of Anaesthesia, M A. Khan, F A. Khan

Department of Anaesthesia

Objective: To evaluate improvement in quality of anaesthesia induction using thiopentone and midazolam for co-induction of anaesthesia. An additional end point was taken as loss of response to a tetanic stimulation (50 Hz) delivered for 5 seconds after the loss of verbal contact and eyelash reflex.Methods: Ninety ASA I and II patients, within the age range of 20-60 years were studied. Patients were randomly divided into three equal groups; A, B and group C.Results: Onset of induction and loss of response to a tetanic stimulation was achieved earlier in group B as compared to the other study groups (p < 0.05).CONCLUSION: Co-induction with midazolam 0.02 mg x kg(-1) followed by thiopentone 3 mg x kg(-1) was superior to other two groups. Induction of anaesthesia in this group was found to be smoother and faster, provided better hemodynamic stability, better airway maintenance and with lesser incidence of untoward effects.

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.

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

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 …
