Auditing Appendectomy in Benue State University Teaching Hospital, Makurdi, Nigeria

Appendicitis is the leading cause of surgical admission in most hospitals in Nigeria and the removed appendix, a frequent surgical specimen in most routine histopathological laborato-ries in Nigeria. The aim of this study is to audit the appendectomy procedures in Benue State University Teaching Hospital. Sixty-two appendices removed for acute appendix in Benue State University Teaching Hospital, Makurdi, Nigeria middle belt, over an 8-year period were analyzed. Twenty-eight (45%) were found to be normal, while 29 (46%) showed histopathological eviden-ce of acute inflammation. There were 5 (9%) cases of unusual pathologies which include a case each of metastatic adenocarcinoma and chronic granulomatous inflammation (2% each) and 3 (5%) cases of schistosomiasis. The Negative Appendectomy Rate (NAR) was 27% in females compared with 18% in males. Adult (>16 years) represented 29% of the NAR. The overall NAR was 45%. The NAR in this study is considerable higher when compared with existing literature. In a poor resource center like Benue State University Teaching Hospital, due diligence in taking detailed history coupled with good clinical examination cannot be over emphasized. The use of a combination of Total Leukocyte Count (TCC) and C-Reactive Protein (CPR) in every patient may help in reducing NAR, though it's definitely going to be impossible to eradicate it.

Characterization of the intensive care unit (ICU) admissions in the Benue State University Teaching Hospital

Today, intensive care units (ICUs) of most hospitals in developed countries have become sepa-rate departments staffed by career intensive care physicians or intensivists from various fields of medicine. In Nigeria, however, ICUs are still part of the anaesthesia department and critical care constitutes a significant part of the workload and responsibilities of anesthetists. This study was carried out to ascertain the types of disease conditions that were brought into the ICU for management at the Benue State University Teaching Hospital (BSUTH), interventions undertaken as well as the outcome of such admissions. A total of 125 patients were evaluated. The age bracket between 21 and 30 years recorded the highest figure of 28 accounting for 22.4% of the study population. This was followed by the age bracket between 31 and 40 years with 24 representing 19.2%. The study population was made up of 81 males and 44 females making up 64.8% and 35.2%, respectively. The most frequent conditions occasioning ICU admissions are post laparotomy (24.8%), head injury (18.4%), and burns (11.2%). A total of 289 inter-ventions in various combinations were carried out on these patients. Of these, monitoring of the patients was undertaken 106 times, representing 36.7%. Oxygen therapy followed closely with 102 (35.3%). The lowest number of days spent by patients in the ICU in this study, was 1, while the longest was 35 with a mean of 5.97 days ± 7.76 days. Majority of the patients, 68, were discharged from the ICU to the wards making up 54.4% of the study population. This was closely followed by those that died, 50, accounting for 40.0% of the study population. This study has established that in our ICU, the most common indications for admission were post-laparotomy, head injury and burns. Also, it has been observed that most of the patients underwent haemod-ynamic monitoring and oxygen therapy. Finally, while most patients admitted were discharged to the wards, a good number also died in the ICU.

Nigerian surgical outcomes - Report of a 7-day prospective cohort study and external validation of the African surgical outcomes study surgical risk calculator.

BACKGROUND: Surgical outcomes study for individual nations remains important because of international differences in patterns of surgical disease. We aimed to contribute to data on post-operative complications, critical care admissions and mortality following elective surgery in Nigeria and also validate the African Surgical Outcomes Study (ASOS) surgical risk calculator in our adult patient cohort. MATERIALS AND METHODS: We conducted a 7-day, national prospective observational cohort study in consented consecutive patients undergoing elective surgery with a planned overnight hospital stay following elective surgery during a seven-day study period. The outcome measures were in-hospital postoperative complications, critical care admissions and in-hospital mortality censored at 30 days. Also, we identified variables which significantly contributed to higher ASOS surgical risk score. External validation was performed using area under the receiver operating characteristic curve (ROC) for discrimination assessment and Hosmer-Lemeshow test for calibration. RESULTS: A total of 1,425 patients from 79 hospitals participated in the study. Postoperative complications occurred in 264(18.5%, 95% CI 16.6-20.6), 20(7.6%) of whom were admitted into the ICU and 16(6.0%) did not survive. Total ICU admission was 57 (4%), with mortality rate of 23.5% following planned admission and overall in-hospital death was 22(1.5%, 95% CI 0.9-2.2). All prognostic factors in the ASOS risk calculator were significantly associated with higher ASOS score and the scoring system showed moderate discrimination (0⋅73, 95% CI 0.62-0.83). Hosmer-Lemeshow χ2 test revealed scale was well calibrated in the validation cohort. CONCLUSION: NiSOS validates the findings of ASOS and the ability of the ASOS surgical risk calculator to predict risk of developing severe postoperative complications and mortality. We identified failure-to-rescue as a problem in Nigeria. Furthermore, this study has provided policy makers with benchmarks that can be used to monitor programmes aimed at reducing the morbidity and mortality after elective surgery. We recommend the adoption of the ASOS surgical risk calculator as a tool for risk stratification preoperatively for elective surgery.

Anaesthetic and surgical management of airway penetrating injuries in children in resource-poor setting: Case reports.

INTRODUCTION: Impacted penetrating foreign body (FB) in the airway especially the postnasal space presents with management challenges. The challenges are worsened by lack of modern equipment in resource-poor settings. Two suchlike cases were managed in this report. PRESENTATION OF CASES: Case 1: A 4-year-old girl who fell on a metal rod in her mouth while playing alone. Examination revealed an agitated child in open mouth posture, with a silvery straight metallic object impacted on the hard palate and projecting from the mouth. X-ray of the post nasal space showed a radiopaque object through the hard palate impinging on the skull base. Case 2: A 5-year-old male presented with swollen neck and difficulty in breathing following a fall on a sharp pencil while at play in school. The object which pierced through the neck was immediately removed by an attendant. Examination revealed a child in obvious respiratory distress with swollen neck, face and eyes with a slit measuring 2cm over the crico-thyroid membrane (subcutaneous emphysema). DISCUSSION: With no available fibre-optic laryngoscope, classical Macintosh laryngoscopy was infeasible. With refusal of tracheostomy, the authors employed three-man intubation technique to successfully secure the airway for excision of the FB in first patient. The second was induced with IV ketamine since he could not tolerate the supine position and facemask. Due to falling oxygen saturation, an orotracheal intubation was done before a successful mid-level emergency tracheostomy was sited. CONCLUSION: Penetrating airway injuries in children pose serious management challenges. Careful anticipation and quick intervention are helpful.
