A Randomised Controlled Trial Investigating The Effect Of Adding Fentanyl To Low Dose Bupivacaine In Combined Spinal-Epidural Anaesthesia, Using Epidural Volume Extension Technique In Caesarean Section, Mudola V. Manyano

Master of Medicine in Anaesthesiology

Background: Epidural volume extension (EVE), is a technique whereby a small-dose intrathecal block is enhanced by an epidural injection of physiological saline. This epidural injection exerts a compression effect on the dura, which then leads to a cranial increase in sensory spread of the intrathecal local anaesthetic. The lower dose of local anaesthetic required in the EVE technique has made it possible to avoid the side effects of the conventional dose of local anaesthetic while still having the benefit of adequate anaesthesia. Several studies have been conducted in this area; these studies have either used or omitted fentanyl. The successful …

Dual Chamber Pacemaker Implants--A New Opportunity In Pakistan For Children With Congenital And Acquired Complete Heart Block, Awais Ashfaq, Mansoor Ahmed Khan, Mehnaz Atiq, Muhammad Muneer Amanullah

Section of Cardiothoracic Surgery

Implantation of cardiac pacemakers has been practiced for at least five decades with continuous developments of the hardware. The invention of dual chamber pacemakers has initiated a debate concerning its superiority over single chamber ventricular pacemakers. Throughout the world, surgeons have been using dual chambered permanent pacemakers with successful follow ups. However, Pakistan has not yet taken the advantage of such pacemaker devices till now. We report three cases that underwent a dual chamber permanent pacemaker implantation for the first time in children less than 8 kg with successful follow ups.

Pregnant Women As Research Participants: Why Is Additional Protection Required?, Kyoko Wada

Research Day (Arts & Humanities, FIMS, and Education)

Today, blanket exclusion of pregnant women from research participation is not endorsed; however, a tendency still remains to exclude pregnant women from participating in research. This exclusion results in insufficient data to guide clinical practice for pregnant women, and hence adds risks to pregnant women and fetuses (Lyerly et al. 2007, 2008, 2009; Baylis 2010; Goldkind et al. 2010).

Predictors Of Postoperative Respiratory Failure In Patients Receiving Anesthesia, Marty Henley

Theses, Dissertations and Capstones

Introduction: Postoperative Respiratory failure has been identified as a prevention quality indicator by The Agency for Health Research and Quality (AHRQ). Postoperative Respiratory Failure is associated with increased length of stay, increased costs and increased morbidity and mortality. Unfortunately, current research is limited regarding scoring methods which are predictive for postoperative respiratory failure. This retrospective case control study was conducted to determine if the various tools of evaluation of risk currently available and to determine if any are predictive of the risk of developing postoperative respiratory failure.

Methodology: The design of this research was a retrospective case control study conducted …

Anaesthetic Challenges In Emergency Surgical Repair Of Acute Aortic Dissection Rupturing Into The Pericardium In A Pregnant Patient, Mohammad Irfan Akhtar, Khalid Samad

Department of Anaesthesia

Acute aortic dissection in pregnancy is a serious situation, because rapid and appropriate surgical decision making is required to save the life of both mother and baby. Aortic dissection is rare in young women but is likely during pregnancy (third trimester) secondary to the hyperdynamic and hypervolaemic circulatory state associated with pregnancy. A 35 years old 27 weeks pregnant patient weighing 90 kg presented in the emergency with severe chest pain. In the immediate post cardiopulmonary bypass period, the patient started bleeding profusely from the anastamotic sites irrespective of utilization of all the conventional methods of haemostasis including multiple units …

Grown Up Congenital Heart Disease Patient Presenting For Non Cardiac Surgery: Anaesthetic Implications, Mohammad Hamid, Mansoor Ahmed Khan, Mohammad Irfan Akhtar, Hameedullah, Saleemullah, Khalid Samad, Fazal Hameed Khan

Department of Anaesthesia

Congenital heart disease patients surviving to adulthood have increased over the years due to various reasons. These patients are admitted in the hospital for non cardiac surgeries and other procedures more often than normal adult population. Management of grown up congenital heart disease patient presents a challenge during perioperative period for cardiologists, surgeons, intensivists and particularly for the anaesthetist. Management issues include psychological and physiological impact on the patient, complexity of defects, presence of previous palliative procedure, impact of anaesthetic agents on shunting and myocardium, endocarditis prophylaxis and associated extra cardiac anamolies.

Intraoperative Insulin Administration And Hypoglycemia In Diabetic Patients, Eric Schwenk, Md, Richard H. Epstein, Md, Cphims, Boris Mraovic

Department of Anesthesiology Faculty Papers

Introduction:

Although studies are conflicting as to the benefit of intensive insulin therapy (IIT) in the critically ill, there is a 6x increase in hypoglycemia incidence in patients treated with IIT.

Anesthesia masks signs and symptoms of hypoglycemia, making intraop hypoglycemia difficult to detect clinically.

We performed this retrospective, observational analysis to:

Determine the incidence of intraoperative hypoglycemia and severe hypoglycemia

Evaluate possible causes of hypoglycemia

Determine intraop monitoring and treatment practices of diabetic patients at a large academic hospital

Introduction:

Electrolytes disorders are a common finding in patients with End stage liver disease (ESLD). Liver transplantation (OLT) is frequently associated with massive transfusion and fluid shifts in patients with renal dysfunction, and management of hyponatremla, hyperkalemia and hypervolemia are major concerns for anesthesiologists. This case describes a multimodal approach in treatment of combined severe hyponatremla, hperkalemia and hypervolemia.

Chemical Dependency: An Occupational Hazard In The Field Of Anaesthesia, Samina Ismail

Department of Anaesthesia

The medical personnel are vulnerable to substance abuse and dependence due to ready access to substance of abuse. Addiction is considered as an occupational hazard for those involved in the practice of anaesthesia for the same reason. Substance abuse is defined as a psychosocial biogenetic disease, which results from dynamic interplay between a susceptible host and favourable environment. According to the 5th and the last National Survey on Drug Abuse (NSDA) in 1993 by Pakistan Narcotic Control, there are nearly three million drug dependants in Pakistan, but no data is available to determine the prevalence among medical or anaesthesia personnel. …

High Inspired Co2 Capnograph Reading Due To Misplaced End Tidal Co2 Sampling Port, Andrew Ng, Md, Elia Elia, Md, Lisa Luyun, Md

Department of Anesthesiology Faculty Papers

In conclusion, if abnormal capnography is seen where the baseline inspiratory CO2 is higher than usual, inspect the circuit for rebreathing and consider examining the position of ETCO2 sampling port. We recommend confirming ETCO2 sampling port is connected immediately distal to Y-piece before starting a case for accurate CO2 measurement.
