Early experience with permanent pacemaker implantation at a tertiary hospital in Nigeria.

INTRODUCTION: artificial pacemakers generate electrical impulses and regulate the heart´s conduction system. They are often used to treat individuals with bradycardia. Permanent pacemaker implantation is a lifesaving procedure especially in patients with symptomatic bradyarrhythmias. The objectives was to evaluate the clinical attributes and outcomes of permanent pacemaker implantation in Ile-ife, Nigeria. METHODS: we retrospectively reviewed medical records of 22 patients who had pacemaker implantation from January 2015 to December 2019. Patient´s demographics, clinical presentation, diagnosis, comorbidities, type of device, complications and long-term follow up were studied. RESULTS: sixteen males (72.7%) and 6 females (27.3%) were recruited into the study with ages ranging between 54 and 84 years and a mean of 70.3 +8.7 years. The commonest symptom was easy fatigability (45.5%) followed by syncope (31.8%). The main indication for permanent pacemaker implantation was complete heart block (86.4%). Seventeen (77.3%) patients had hypertension as the comorbidity present at diagnosis. Single chamber (VVIR) pacemaker was implanted in 13(59.1%) patients while dual chamber (DDDR) was implanted in 9(40.9%) patients. Hematoma, pneumothorax and acute lead dislodgement were the complications observed in 3 patients. There was no statistical significance between the type of device implanted and the occurrence of complications, p-value 0. 186. There was no mortality and 15 patients (68.2%) are currently attending regular 6 monthly follow-up. CONCLUSION: complete heart block is the most common indication for permanent pacemaker implantation and the procedure is safe with minimal complications and satisfactory outcomes.

Comparison between flutter valve drainage bag and underwater seal device for the management of non-massive malignant and paramalignant pleural effusions.

INTRODUCTION: The aim of this study is to compare the use of flutter valve drainage bag system as an alternative to conventional underwater seal drainage bottle in the management of non-massive malignant/paramalignant pleural effusion. METHODS: Forty-one patients with non-massive malignant and paramalignant pleural effusions were randomized into two groups. Group A (21patients) had their chest tubes connected to an underwater seal drainage bottle, while group B (20 patients) had their chest tubes connected to a flutter bag drainage device. Data obtained was analyzed with SPSS statistical package (version 16.0). RESULTS: Breast cancer was the malignancy present at diagnosis in 24(58%) patients. Complication rates were similar, 9.5% in the underwater seal group and 10 % in the flutter bag drainage group. The mean duration to full mobilization was 35.0±20.0 hours in the flutter bag group and 52.7±18.5 hours in the underwater seal group, p-value 0.007. The mean length of hospital was 7.9±2.2 days in the flutter bag group and 9.8±2.7 days in the underwater seal group. This was statistically significant, p-value of 0.019. There was no difference in the effectiveness of drainage between both groups, complete lung re-expansion was observed in 16(80%) of the flutter bag group and 18(85.7%) of the underwater seal drainage group, p-value 0.70. CONCLUSION: The flutter valve drainage bag is an effective and safe alternative to the standard underwater seal drainage bottle in the management of non-massive malignant and paramalignant pleural effusion.

Pattern of Extremity Arterial Injury and Outcome of Repair in Southwest, Nigeria.

BACKGROUND: Extremity arterial injuries are an important cause of loss of life/limb after trauma. Early intervention is important for the good outcome. OBJECTIVES: The objective of this study is to review the pattern of presentation and study the factors that influences the outcome of extremity arterial injuries in our hospital. PATIENTS AND METHODS: This is a retrospective study of all patients with injuries to the extremity arteries requiring surgical intervention from July 2007 to June 2015. Data obtained included biodata, ischemic time, arteries involved, surgical intervention, and outcomes and analyzed using SPSS version 22. SETTING: Our hospital is the main referral hospital for vascular trauma serving four adjoining states in Nigeria and is linked to major cities by at least 3 Trunk-A federal roads. SUBJECTS: The subjects are patients who were managed in our cardiovascular surgical unit for the study duration (July 2007-June 2015) who had extremity arterial injuries. RESULTS: A total of 36 patients presenting with 40 arterial injuries in 37 limbs were studied. The mean age was 28.4 ± 10.3 years with male preponderance (88.9%). Gunshot injuries were the most common cause of arterial injuries (37.8%), followed by assault (27%). The mean time from injury to presentation for acute injuries was 20.4 h but 23 of the patients (63.8%) presented to the accident and emergency department within 12 h of injury. A limb salvage rate of 64.9% was achieved though ischemic times of ≥12 h were associated with poor outcomes. CONCLUSION: Prolonged ischemic time is associated with poor outcomes. Efforts should be put in place to reduce the limb ischemic times.

Early experience with open heart surgery in a pioneer private hospital in West Africa: the Biket medical centre experience.

INTRODUCTION: More than forty years after the first open heart surgery in Nigeria, all open heart surgeries were carried out in government-owned hospitals before the introduction of such surgeries in 2013 at Biket Medical Centre, a privately owned hospital in Osogbo, South-western Nigeria. The aim of this paper is to review our initial experience with open heart surgery in this private hospital. METHODS: All patients who underwent open heart surgery between August 2013 and January 2014 were included in this prospective study. The medical records of the patients were examined and data on age, sex, diagnosis, type of surgery, cardiopulmonary bypass details, complications and length of hospital stay were extracted and the data was analysed using SPSS version 16. RESULTS: Eighteen patients comprising of 12 males and 6 females with ages ranging between 8 months and 52 years (mean= of 15.7 +/- 15 years) were studied. Pericardial patch closure of isolated ventricular septal defect was done in 7 patients (38.9%) while total correction of isolated tetralogy of Fallot was carried out in 5 patients (27.8%). Two patients had mitral valve repair for rheumatic mitral regurgitation. Sixty day mortality was 0%. CONCLUSION: Safe conduct of open heart surgery in the private hospital setting is feasible in Nigeria. It may be our only guarantee of hitch free and sustainable cardiac surgery.
