A Review Of Critical Care Management Of Maternal Sepsis, Madiha Hashmi, Fazal Hameed Khan

Department of Anaesthesia

Sepsis is a leading cause of preventable maternal mortality in developing countries due to poverty, home deliveries by untrained persons in unhygienic conditions, limited access to healthcare facilities and lack of availability of antibiotics. Recent confidential enquiries into maternal deaths from the developed nations have revealed an increase in maternal mortality secondary to genital tract sepsis and provision of suboptimal critical care. Early recognition of critical illness in obstetric patients, involvement of intensive care teams earlier and provision of same standard of critical care to pregnant women as non-pregnant patients while being mindful of the altered maternal physiology and fetal …

Culturable Aerobic And Facultative Anaerobic Intestinal Bacterial Flora Of Black Cobra (Naja Naja Karachiensis) In Southern Pakistan, Junaid Iqbal, Mehwish Sagheer, Nazneen Tabassum, Ruqaiyyah Siddiqui, Naveed Ahmed Khan

Department of Biological & Biomedical Sciences

Using morphological analysis and biochemical testing, here for the first time, we determined the culturable gut bacterial flora (aerobes and facultative anaerobes) in the venomous Black Cobra (Naja naja karachiensis) from South Asia. The findings revealed that these snakes inhabit potentially pathogenic bacteria including Serratia marcescens, Pseudomonas aeruginosa, Shewanella putrefaciens, Aeromonas hydrophila, Salmonella sp., Moraxella sp., Bacillus sp., Ochrobactrum anthropi, and Providencia rettgeri. These findings are of concern, as injury from snake bite can result in wound infections and tissue necrosis leading to sepsis/necrotizing fasciitis and/or expose consumers of snake meat/medicine in the community to infections.

Effect Of L-Type Calcium Channel Blocker (Amlodipine) On Myocardial Iron Deposition In Patients With Thalassaemia With Moderate-To-Severe Myocardial Iron Deposition: Protocol For A Randomised, Controlled Trial, Amarah Shakoor, Maaman Zahoor, Alina Sadaf, Najveen Alvi, Zehra Fadoo, Arjumand Rizvi, Farheen Quadri, Fateh Ali Tipoo, Mohammad Khurshid, Zaffar Sajjad, Steven Colan, Babar S Hasan

Department of Paediatrics and Child Health

Introduction: Sideroblastic cardiomyopathy secondary to repeated blood transfusions is a feared complication in thalassaemia. Control of myocardial iron is thus becoming the cornerstone of thalassaemia management. Recent evidence suggests a role for L-type Ca²⁺ channels in mediating iron uptake by the heart. Blocking the cellular iron uptake through these channels may add to the benefit of therapy to standard chelation in reducing myocardial iron. We aim to determine the efficacy of amlodipine (a calcium channel blocker) as an adjunct to standard aggressive chelation in retarding myocardial iron deposition in thalassaemics with or without cardiomyopathy.
Outcomes: The primary outcome …

A Randomized Control Trial Comparing Weight Adjusted Dose Versus Fixed Dose Prophylactic Phenylephrine Infusion On Maintaining Systolic Blood Pressure During Caeserean Section Under Spinal Anaesthesia, Lucy Wambui Mwaura

Theses & Dissertations

Background: Spinal anaesthesia is the standard of care for elective caesarean delivery. Its advantages over general anaesthesia include: decreased blood loss, reduced postoperative pain and faster recovery time. Despite these advantages, the sympathetic blockade induced by spinal anaesthesia results in 80 percent incidence of hypotension without prophylactic management. This hypotension can cause: nausea, vomiting, cardiovascular collapse or even loss of consciousness in the mother, and fetal acidosis.

Current evidence supports co-loading with intravenous fluids in conjunction with the use of vasopressors as the most effective way to prevent and treat the hypotension. Phenylephrine is the accepted vasopressor of choice in …

The Heart Weight–Body Weight Coefficient In Kenyans Aged 14 Years And Above, Mbayah Etabale

Theses & Dissertations

Background: The heart size has traditionally been assessed using absolute reference weights. But the heart weight (HW) has been shown to depend on one’s body size hence a better measure is the ratio of the HW to the body weight (BW) – the HW-BW coefficient. Initially noted to be 0.43% and 0.40% in males and females respectively, recent studies have shown an increase of up to 0.51%.

Objective: To determine the HW-BW coefficient in Kenyans aged 14 years and above.

Methods: One hundred and four deceased Kenyans aged 14 years and above, with no heart or chronic lung disease, were …

Association Between Parity And Rubella Seropositivity Among Older Reproductive-Age Women, Ibtisam Salim Awadh

Racecadotril For The Treatment Of Severe Acute Watery Diarrhoea In Children Admitted To The Kenyatta National Hospital - A Randomised Double Blinded Placebo Controlled Trial, Jaspreet Singh Gharial

Theses & Dissertations

Background: Diarrhoeal disease is the second most common cause of death in children under 5 years of age in Kenya. Treatment with Oral Rehydration Solution (ORS), elemental zinc and continued feeding (as recommended by the World Health Organisation) led to a significant reduction in mortality in the 1970s and 1980s, which has slowed since then. Adjunctive treatments have however, not gained much popularity either due to modest improvements in morbidity and mortality or unacceptable adverse effect profiles. Racecadotril, an enkephalinase inhibitor, has been used for over 2 decades in parts of Europe but is only recently gaining recognition in …

Responding To Health Care Complexity: Suggestions For Integrated And Interprofessional Workplace Learning, Pim Kuipers, Carolyn Ehrlich, Sharon Brownie

School of Nursing & Midwifery, East Africa

This report highlights complexity in health care and the relevance of integrated and interprofessional care and learning. It is proposed that appropriate workforce training in response to complexity should be contextually relevant and workplace integrated, and should focus on building interprofessional capability for reflective practice and critical thinking. This training should be interprofessional and foster systems thinking. It is suggested that the World Health Organization's International Classification of Functioning, Disability and Health (ICF) is a useful integrating framework.

Rising To The Challenge: Nursing Leadership Via Nurse-Led Service Provision For Chronic Disease Management And Prevention, Gary E. Day, Sharon Brownie

School of Nursing & Midwifery, East Africa

All nations are currently challenged by the increasing prevalence of non-communicable and chronic disease [1]. In Australia, by 2051, over 50% of the population over 50 will have a chronic disease [2]. In addition to increased levels of chronic disease, services will be stretched through workforce shortages, and government policies to provide greater access to services. Within the United States of America demand for primary care services will further increased by the passage and progressive implementation of the Affordable Care Act (ACA), which expands Medicaid coverage to millions of low-income Americans [3]. Given the increasing levels of disease burden, all …
