Anaesthetic Management Of Neonatal Primary Hyperparathyroidism, Anwar-Ul-Huda, Sanam Dost Mohammad, Tauseef Ahmed

Department of Anaesthesia

Neonatal primary hyperparathyroidism (NPHP) is a rare disease that presents in the first 6 months of life. It is almost invariably fatal unless a prompt diagnosis is made and urgent surgical intervention is instituted. Patients with hyperparathyroidism require special preoperative considerations. They require proper work-up from cardiac, renal and neurological point of view, correction of intravenous volume and electrolytes irregularities. We are presenting a case of an infant who started to have cyanosis and lethargy at 21st day of life. Initial diagnosis of pneumonia was made but later on diagnosed as hyperparathyroidism. He was planned for parathyroidectomy under general anaesthesia. …

A Randomised Controlled Trial Comparing Haemodynamic Stability In Elderly Patients Undergoing Spinal Anaesthesia At L5,S1 Versus Spinal Anaesthesia At L3,4 At The Aga Khan University Hospital, Nairobi, Karen Nkatha Mbaya

Master of Medicine in Anaesthesiology

Background: Spinal anaesthesia is a routinely used anaesthetic technique for elderly patients undergoing operations involving the lower limbs, lower abdomen, pelvis and the perineum. Spinal anaesthesia has several advantages over general anaesthesia and these include stable haemodynamic variables, less blood loss, less post operative pain, faster recovery time and less post operative confusion. However, despite these advantages, the sympathetic blockade induced by spinal anaesthesia can result in hypotension, bradycardia, dysrhythmias and cardiac arrests. Conventionally, spinal anaesthesia is performed at the level of L3,4 interspace; with a reported incidence of hypotension in the elderly ranging between 65% and 69%. A possible …

Factors That Motivate Certified Registered Nurse Anesthetists To Practice Independently In The Appalachian Region, Michael Lee Frame Jr.

Theses, Dissertations and Capstones

Introduction: Independent Certified Registered Nurse Anesthetists (CRNAs) provide anesthesia services without the supervision or medical direction of anesthesiologists in healthcare facilities throughout the United States. The present literature is limited concerning the factors that motivate CRNAs to choose employment in rural independent practice.

Research Hypothesis: In a sample of CRNAs who practice independently in one of the 13 states of the Appalachian region there will be no differences between the CRNAs from Appalachian and Non-Appalachian counties in their responses to the motivation factors of achievement, recognition, responsibility, advancement, work itself, salary, working conditions, company and administrative policies, supervision, and …

Risk Factors For Ventilator-Associated Pneumonia In The Adult Trauma Patient: A Retrospective Case-Control Study From A Level I Trauma Center, Summer L. Chapman

Theses, Dissertations and Capstones

Introduction: Ventilator-Associated Pneumonia (VAP) continues to be a common complication among the adult trauma population. Little advancements have been made to decrease the incidence, suggesting further research is needed to establish modifiable risk factors. The purpose of this study was to test for an associated link between prehospital intubation and the development of VAP in the adult trauma patient.

Methodology: A retrospective, case-control study design was utilized. The sample included 494 adult trauma patients who required endotracheal intubation and mechanical ventilation for a minimum of 24 hours. All patients presented as a priority one or two trauma to the Charleston …

Our Experience With Two Cardioplegic Solutions: Dextrose Versus Non-Dextrose In Adult Cardiac Surgery, R. Lessen, J. Dicapua, R. Pekmezaris, R. Walia, K. Bocchieri, L. Jahn, M. Akerman, M. L. Lesser, A. Hartman

Journal Articles

Intraoperative hyperglycemia has been observed to be associated with increased morbidity and mortality after cardiac surgery. Dextrose cardioplegia is used for its cardioprotective effects but may lead to intraoperative hyperglycemia and more postoperative complications. This was a retrospective observational study. Patient records (n = 2301) were accessed from a large database at a tertiary care facility. The two groups (dextrose vs. nondextrose) were then matched using preoperative variables of age, sex, body mass index, wound exposure time, preoperative HbA1c levels, renal failure, hypertension, and prior cerebrovascular disease. The following outcomes were recorded: 30-day mortality, sternal wound infection, stroke, and highest …

Department of Anesthesiology Faculty Papers

Introduction:

Acute hypotensive transfusion reactions are characterized by an abrupt and early onset of hypotension. This is often severe and lacks other signs of symptoms associated with more common causes of hypotension or transfusion reactions. Once the transfusion is stopped, the hypotension rapidly resolves, usually without the need for therapy.

Anaesthetic Management Of Abdominal Hysterectomy In Patient With Congenital Sinus Node Dysfunction, Dileep Kumar, Faisal Shamim

Department of Anaesthesia

A 45 years old woman having dysfunctional uterine bleeding was scheduled for total abdominal hysterectomy with bilateral salpingo-oophorectomy under general anaesthesia. On pre-operative anaesthesia assessment, she was found to have junctional rhythm at rate of 44 beats/minute with bigeminies and pre-mature ventricular contractions on ECG. On further evaluation, she was diagnosed as having congenital sinus node dysfunction on the basis of 24 hours Holter monitoring. She was asymptomatic, no prior comorbidity and belonged to functional class one. General anaesthesia was successfully managed by vigilance, invasive monitoring, standby transcutaneous and transvenous pacemakers; use of cardiostable and vagolytic anaesthetic agents like Etomidate, …

Magnesium, A Drug Of Diverse Use, Mohammad Irfan Akhtar, Hameed Ullah, Mohammad Hamid

Department of Anaesthesia

Magnesium has evolved as a drug with diverse clinical applications. Mg++ is an important caution and its homeostasis is very important for normal body functioning. The physiological role of Mg is due to its calcium channel blocking properties at smooth muscle, skeletal muscle and conduction system levels. The analgesic properties are due to NMDA receptor blocking action. Mg++ is beneficial in acute Myocardial Infarction, protection during open heart surgery and treatment and prevention of heart rhythm disturbances. Mg has an established role in the management of preeclampsia and eclampsia. Magnesium prevents or controls convulsions by blocking neuromuscular transmission and decreasing …
