Item Airway obstruction following snake bite. A case report.(Journal of the Societies of Anaesthetists of West and East Africa., 2003) Bolaji, Benjamin olusomiA 25-year old farmer was referred from a private clinic to the University of Ilorin Teaching Hospital (UITH) with a 6-day history of snake bite in his farm. He was conscious on admission and had bleeding tendencies. His PCV on admission was 10%. A diagnosis of vasculotoxic snake bite was made. The patient was admitted, treated with anti-snake venom (ASV) and was transfused with 8 units of fresh whole blood. He subsequently developed a massive oedema of the tongue resulting in upper airway obstruction requiring urgent intervention. The anaesthesia team was invited for possible endotracheal intubation. The airway management is presented.Item Anaesthesia for right adrenalectomy in a patient with phaeochromocytoma in a resource-challenged facility- case report.(College of Health Sciences, University of Ilorin, Ilorin, Nigeria., 2013) Bolaji, Benjamin olusomi; Oyedepo, olubukola Olanrewaju; Ige, Olufemi Adebayo; Rahman, Ganiyu Adebisi; Olatoke, Samuel; Agodirin, SOWe present a case of phaeochromocytoma in a 22 year old female who had adrenalectomy done in our hospital as our first experience in 25 years. The patient presented with 2 months history of low grade fever, excessive sweating and throbbing headache. Her blood pressure on presentation was 190/140 mm Hg. A diagnosis of phaeochromocytoma was made from the history, clinical examination, ultrasound finding of a suprarenal mass and raised urine catecholamine levels. Preoperatively, blood pressure was controlled with prazosin and propranolol. She had right adrenalectomy under general anaesthesia. Intraoperatively, blood pressure was controlled with infusion of hydrallazine and intermittent bolus doses administered during surges in blood pressure. Adrenaline infusion and bolus doses were used to treat hypotension after excision of the tumour. The postoperative course was uneventfulItem Anaesthesia management for thyroidectomy in a non-euthyroid patient following cardiac failure.(Medical and Dental Consultants Association of Nigeria, 2011) Bolaji, Benjamin olusomi; Oyedepo, Olanrewaju Olubukola; Rahman, Ganiyu AdebisiWe present a 24-year old thyrotoxic student of a tertiary institution who had thyroidectomy in the presence of a persistently elevated thyroxine (T4) and tri-iodothyronine (T3) levels. The patient who did not initially notice that he had an anterior neck swelling was being managed as a case of hypertension at a private hospital. However, his mother’s insistence that he should seek expert management revealed that he had experienced excessive sweating, undue heat intolerance of 3 years duration and easy fatigability of a month’s duration at the time of presentation at our hospital. He had bilateral anterior neck masses on examination. He was subsequently diagnosed as a case of toxic goiter with biochemical evidence of elevated T3 and T4 levels. The patient was commenced on anti-thyroid drugs but he developed cardiac failure after 6 months on medical treatment and was commenced on anti-failure regime. Surgery was postponed several times due to persistently elevated thyroid hormones. A decision to perform thyroidectomy was taken after the patient’s cardiovascular status was optimized in order to prevent further deterioration of his cardiac function. Serial repeat thyroid hormone profiles showed elevated T3 and T4 levels. The patient eventually had subtotal thyroidectomy uneventfully after 9 months of presentation under general anaesthesia. Contingency plans for managing thyroid storm in the perioperative period were ensured. The anaesthetic management is presented and discussed.Item Comparative evaluation of 0.5% ropivacaine and 0.5% bupivacaine for day case inguinal herniorrhaphy in a Nigerian tertiary hospital.(Journal of the Societies of Anaesthetists of West and East Africa., 2010) Bolaji, Benjamin olusomi; Yusuf, IF; Rahman, Ganiyu Alege; Kuranga, Sulyman Alege; Oyedepo, Olanrewaju OlubukolaBACKGROUND: Day case inguinal herniorrhaphy is a common surgical procedure performed in our environment with lidocaine used for field block. The study was aimed at comparing 0.5% ropivacaine and 0.5% bupivacaine for the field block, determine their effectiveness and safety in our environment. METHODS: In a double-blind randomized study, 52 ASA physical status I-II patients (age ≥ 18yrs) scheduled for field block for day case inguinal herniorrhaphy were assigned to two study groups to receive 0.5% ropivacaine 25ml (n = 26) or 0.5% bupivacaine 25ml (n = 26). Onset of analgesia, adequacy of block, duration of postoperative pain relief and pain score at first requirement of analgesic were recorded. RESULTS: One patient in the bupivacaine group did not complete the study. Patient demographics and surgical times were similar in the two groups. Mean onset time of anaesthesia was shorter in the bupivacaine group than the ropivacaine group (5.37± 0.50 min vs 5.48 ± 0.45 min) although this was not significant (P = 0.44). Adequacy of block was similar in the two groups (P = 0.55). Postoperative pain relief was significantly longer for the ropivacaine group 6.83 ± 0.57hr than for the bupivacaine group 6.32 ± 0.35 hr (P = 0.0004, unpaired t-test). Mean pain score at the first requirement for analgesic was lower in the ropivacaine group 1.38 ± 0.49 than the bupivacaine group (1.56 ± 0.51), but this was not significant (P = 0.22). Few untoward effects of nausea and dizziness were observed in this study. CONCLUSION: Ropivacaine and bupivacaine have comparable onset of actions and adequacy of anaesthesia when used for day case inguinal herniorrhaphy and are safe.Item Comparison of topical lidocaine (2% gel) and injectable lidocaine (2% solution) for incision and curettage of chalazion in Ilorin, Nigeria.(The Nigerian Post graduate Medical College, 2010) Osayande, OO; Mahmoud, AO; Bolaji, Benjamin olusomiAIMS AND OBJECTIVES: To compare the efficacy and side effects of profile of topical 2% lidocaine gel with injectable 2% lidocaine solution as local anaesthetics for incision and curettage of chalazion. PATIENTS AND METHODS: Over a 12-month period, 61 patients with unilateral chalazia who were scheduled for incision and curettage surgery under local anaesthesia were randomlzed into two groups: A and B. Group A received 1.5ml of injectable lidocaine as local anaesthetic while group B received 1.5 ml of lidocaine 2% gel topically. The major outcome of interest was pain experienced during anaesthetic administration and surgery. RESULTS: Mean pain score from anaesthesia administration was significantly higher in the injection group (A = 4.46 vs B =0.57), (p = 0.000005). There was a statistically significant difference in mean pain score during incision and curettage with more pain in the gel group (A = 2.84 vs B = 4.83), (p = 0.0012). However, the mean total pain score (surgery plus anaesthesia) was more in the injection than the gel group (A= 7.3 vs B = 5.4) (p= 0.0094). The proportions that had no fear for injection were 54.8% in A and 56.7% in B. Group A had significantly more ptosis than group B (2.2 vs 1.4, p = 0.00003). Bleeding occurred in 93.5% in group A while none occurred in group B (p = 0.000). CONCLUSION: Lidocaine 2% gel is an effective, safe and convenient alternative to injectable lidocaine 2% as local anaesthetic agent in incision and curettage for chalazion in this study.Item Epidemiology of severe pre-eclampsia and eclampsia in Ilorin.(Library and Publications Committee, University of Ilorin, Ilorin,, 2013) Bolaji, Benjamin olusomi; Oyedepo, olubukola Olanrewaju; Saidu, Rakiya; Aderibigbe, SA; Fawole, AA; Balogun, Olayinka Rabiu; Aboyeji, Abidun Peter; Jimoh, AbdulGaffar AG; Olawumi, Hannah O; Adebisi, SAThis study was carried out over a 10-month period in the University of Ilorin Teaching Hospital to determine the frequency and epidemiological factors of severe preeclampsia and eclampsia in Ilorin, North-central Nigeria. This was a prospective study of severely preeclamptic and eclamptic patients admitted to the labour ward of the UITH. Patients with normal pregnancies who agreed to participate were the control group. Demographic, clinical variables, maternal and foetal outcomes, and, complications were assessed. One hundred women (50 study group & 50 control group) participated in the study. Statistically significant findings among the study group included lower GA at delivery (p=0.0001), family history of hypertension (p=0.02), new partner (0.001), more interventions at delivery (p=0.000), higher number of preterm deliveries (0.000). Though 2 maternal deaths and 5 perinatal deaths were recorded in the study group, none occurred in the control group. Deeper understanding of the epidemiology of severe preeclampsia and eclampsia is very important to finding ways to further lower its contribution to maternal mortality in our societiesItem Post operative intensive care admissions of paediatric surgical patients in a Nigerian tertiary hospital: indications and evaluation of management outcome.(Journal of the Societies of Anaesthetists of West and East Africa., 2008) Bolaji, Benjamin olusomi; Nasir, AA; Adeniran, James O; Abdur-Rahman, Lukman O; Oyedepo, Olubukola OlanrewajuA retrospective study of all paediatric surgical patients aged 15 years and below, admitted into the Intensive Care Unit (ICU) of the University of Ilorin Teaching Hospital (UITH) following surgery was carried out, covering a period of 10 years. Demographic information, surgical procedures performed, indications for intensive care admission and outcome were obtained. Sixty-seven general paediatric surgical patients were admitted with a male to female ratio of 1.4:1. There were 32 (47.8%) infants, 6(9%) pre-school children and 29(43.3%) older children. There were 57(85.1%) emergency procedures. Of the 40 patients who had documented indications for admission, 25(62.5%) had respiratory insufficiency. Twenty (29.9%) of the 67 admitted patients died. Out of 25 patients that required ventilation for respiratory insufficiency, only five (20.0%) were ventilated. Primary diagnosis, American Society of Anesthesiologists’ (ASA) physical status score, emergency surgery and type of procedure significantly affected outcome. Conclusion: Availability of appropriate paediatric ventilatory facilities and personnel may reduce mortality in our ICU.Item Preinduction oral clonidine: Effects on ketamine cardiostimulation at induction of anaesthesia.(College of Medical Sciences, University of Jos, Jos, 2016) Suleiman, Zakari Aliyu; Kolawole, Israel Kayode; Bolaji, Benjamin olusomiMost of the available intravenous (IV) induction agents produce hypotension except ketamine. However, its use is limited due to cardiovascular stimulation. We therefore investigated the effects of oral clonidine premedication on ketamine-induced cardiostimulation. This was a prospective, double-blind randomized controlled study of 156 patients scheduled for general anaesthesia. The patients were randomized into three Groups A, B and C of 52 patients each and all the patients received 10mg diazepam the night before the surgery and 90 minutes before induction of anaesthesia. In addition, patients in Groups A and B received 0.1 mg and 0.3 mg oral clonidine, respectively, at the time of premedication while no clonidine was administered in Group C. Anaesthesia was induced with IV ketamine 2mg/kg and 100% oxygen 8 L/min via the Bain circuit. The pulse rate (PR), systolic blood pressure, diastolic blood pressure, and mean arterial pressure were measured noninvasively and recorded every 10 min before induction of anaesthesia. RESULTS: The peak values of PR in the 0.1 mg and 0.3 mg clonidine groups were significantly lower than the corresponding value in the control (C) group (86 ± 5 bpm and 83 ± 7 bpm vs. 118 ± 14 bpm, p < 0.05). however, the peak mean blood pressure in Group B was significantly reduced when compared with the corresponding values in the Groups A and C (97 ± 9 mm Hg vs 117 ± 7 mm Hg and 115 ± 14 mm Hg, respectively p < 0.05. Preanaesthetic oral clonidine reduced cardiostimulation following ketamine-induction in spontaneously breathing patients.Item A review of anaesthesia for orthopaedic surgery in the University Teaching Hospital, Ilorin, Nigeria.(Library and Publications Committee, University of Ilorin, Ilorin,, 2005) Bolaji, Benjamin olusomiA retrospective study was made on all patients who had orthopaedic surgical procedures between March 2001 and February 2002 at the University of Ilorin Teaching Hospital (UITH), Ilorin, Nigeria. The aim of this study was to review the various anaesthetic techniques offered to orthopaedic patients, the procedures done, perioperative adverse events and to suggest areas of improvement. Data were obtained from anaesthetic record charts, case files, theatre, recovery room, intensive care unit records and the Department of Health Records of UITH. Statistical analysis was carried out using the Chi square test. A p value of less than 0.05 was considered significant. The results showed that a total of 178 patients had 203 orthopaedic surgical procedures within the study period. There were 121 (68%) males and 57 (32%) females. Intercurrent medical illness was found in 11.8% of the patients. The most commonly performed orthopaedic surgical procedure was open reduction and internal fixation (30%), followed by sequestrectomy (12.3%). General anaesthesia was the most commonly performed technique (69.7%), followed by subarachnoid block (21.3%). Perioperative adverse events occurred in 16.9% of the patients, shivering occurring in 30%, hypotension in 23.4% and hypertension in 16.7% of those who had adverse events. There was no significant association between American Society of Anesthesiologists' (ASA) grading and occurrence of perioperative adverse events. Availability of appropriate anaesthetic drugs of choice and reduction in homologous blood use are advocated.Item Stage correction of intermediate imperforate anus in males: preliminary results.(The Surgical Sciences Research Society, Zaria and Association of Surgeons of Nigeria, Zaria, Nigeria., 2004) Adeniran, James O; Abdul-Rahman, Lukman O; Bolaji, Benjamin olusomiBACKGROUND: This prospective study was designed to assess the safety, cost-effectiveness, and advantages of performing posterior saggital anorectoplasty without colostomy on males with intermediate imperforate anus. METHOD: Five consecutive males with intermediate imperforate anus were entered into the study. Chest and abdominal x-rays, skeletal surveys, renal ultrasound scans, and invertograms were done. Patients were resuscitated, and Pena's posterior saggital anorectoplasty 9PSARP) done in prone position. Tow-ml syringe vents were inserted into the new anus for 10 days. Cephalosporin and metronidazole were given as peri-operative antibiotics. RESULTS: All patients had intermediate anomalies. There were no other major associated congenital anomalies. Urethral catheter could not be inserted in one patient. One patient presented with septicaemia and jaundice. He was deemed too ill to withstand a major operation. These 2 patients therefore had diverting colostomies. There were no problems with posterior saggital anorectoplasty in the other 3 patients. The father of one patient discharged him against medical advice on the 5th postoperative day. The mother had post-partum haemorrhage and they went for traditional treatment because they could not provide blood donors. The skin wound of 2 patients healed completely at removal of stitches. Both are having monthly dilatations 9 months and 1 year post-operatively. CONCLUSION: This preliminary study shows that it is feasible for males with intermediate imperforate anus to have safe posterior saggital anorectoplasty without colostomy. The advantages of one, instead of 3 major operations, are many, especially in developing countries. If this result can be reproduced in high anomalies colostomy may be unnecessary in many cases of anorectal malformations with a lot of benefits to these unfortunate children and their poor families.
