Effect of spinal anesthesia on QT interval: Comparative study of severe pre-eclamptic and normotensive parturients undergoing cesarean section.

Aim: This study aimed to compare the effect of spinal anesthesia on QT interval in severe pre-eclamptic and normotensive parturients who underwent cesarean section in a Nigerian tertiary hospital. Patients and Methods: Twelve-lead electrocardiogram (ECG) was obtained before, and at intervals after spinal anaesthesia on fifty severe pre-eclamptic (Group A) and fifty normotensive parturients (Group B) who underwent caesarean section. The effect of spinal anaesthesia on QT interval was compared. Results: The preoperative (baseline) mean QT interval was longer in group A than in group B; 453.10 ± 34.11 ms versus 399 ± 18.79 ms, P < 0.001. The prevalence of prolonged QT interval in the severe pre-eclamptic group before spinal anesthesia was 80% while in the normotensive group it was 0%, P < 0.001. At 5, 30, 60, and 120 min after the establishment of spinal anesthesia, the mean QT interval in the severe pre-eclamptic group was shortened and maintained within normal limits; 414.74 ± 28.05, 418.28 ± 30.95, 411.18 ± 19.21 and 401.36 ± 17.52 ms with P < 0.001 throughout. In the normotensive group, there was no significant change in the mean QT interval. Conclusions: This study demonstrated that the QT interval was more prolonged among the severe pre-eclamptic parturients. Spinal anesthesia using 0.5% hyperbaric bupivacaine normalized the QT interval and maintained it within normal limits during the study period.

Atherogenic and cardiovascular risks of women on combined oral contraceptives: A comparative study.

BACKGROUND: Although combined oral contraceptive (COC) is commonly used in sub-Saharan Africa, data on its cardiovascular disease risk remains scanty. The study aimed to determine serial serum lipid profiles and cardiovascular disease risks among COC-users. METHODS: This is a prospective, comparative multicentered study conducted at four health facilities in Nigeria. Participants were new users of contraceptives; 120 each of women initiating COCs (group I) and those initiating other forms of nonhormonal contraceptives (group II) were recruited and monitored over a 6-month period. Serial lipid profile, blood pressure, and atherogenic risk for cardiovascular diseases were measured at recruitment (start) and scheduled follow-up clinic visits at 3 months and 6 months for all participants. Statistical analysis was performed with SPSS (version 21.0) and P value < 0.05 was considered significant. RESULTS: In all, 225 participants (111 COC-users, 114 nonCOC-users) that completed the study were aged 18 to 49 years. There was a statistically significant increase in the diastolic blood pressure (P = 0.001), Low Density Lipoprotein- Cholesterol (P = 0.038) and higher atherogenic risk (P = 0.001) among COC-users compared to nonCOC-users. The serial total serum cholesterol, triglyceride, High Density Lipoprotein, systolic blood pressure, and body mass index were higher among COC-users but were not statistically significant compared to nonCOC-users. CONCLUSION: Alterations in lipid profile and increased short-term atherogenic risk for cardiovascular disease were reported among the COC-users in this study. Serial lipid profile and atherogenic risk assessment for cardiovascular diseases are recommended for monitoring of COC-users.

Coping strategies among patients attending HIV clinics in a North-central State of Nigeria.

BACKGROUND: Nigeria ranks third among the countries with the highest HIV/AIDS burden in the world, next only to India and South Africa. The North-Central zone which Kwara State belongs to has the highest concentration of HIV prevalence rate of 7.5%, while the North-Western zone recorded the lowest prevalence of 2.1%; Kwara state has a prevalence rate of 2.2%. AIMS: The study assessed the coping strategies adopted by patients attending HIV clinics in a North-central city of Nigeria. METHODS: The study design was descriptive cross-sectional involving 384 HIV-positive patients who were systematically recruited at 5 public service delivery sites in Ilorin- a North-central city, Nigeria was used for the study. Coping strategies were measured using the Brief COPE scale. Data were analyzed using SPSS software version 20.0. Level of significance was pre-determined at P value <0.05 at a confidence level of 95%. RESULTS: Female respondents constituted 222 (58.0%) while males were 162 (42.0%). Respondents experienced varying proportion of coping strategies of which Self-distraction 288 (75.0%), active coping 249 (64.8%), emotional support 228 (59.4%), among others were the major strategies adopted by respondents. CONCLUSION: HIV is a chronic disease with heavy burden on both patients and health facility rendering services for the care of these patients. A good proportion of respondents interviewed adopted varying coping strategies. Sustained social and psychological support will improve further the coping strategies of living with HIV.
