    Good postoperative analgesic management improves maternal satisfaction and care of the neonate. Postoperative pain management is a challenge in Mulago Hospital, yet ketamine is accessible and has proven benefit. We determined ketamine’s postoperative analgesic effects. Materials and Methods. We did an RCT among consenting parturients that were randomized to receive either intravenous ketamine (0.25 mg/kg) or placebo after spinal anesthetic. Pain was assessed every 30 mins up to 24 hours postoperatively using the numerical rating scale. The first complaint of pain requiring treatment was noted as “time to first breakthrough pain.” Results. We screened 100 patients and recruited 88 that were randomized into two arms of 44 patients that received either ketamine or placebo. Ketamine group had 30-minute longer time to first breakthrough pain and lower 24-hour pain scores. Postoperative diclofenac consumption was lesser in the ketamine group compared to placebo and Kaplan-Meier graphs showed a higher probability of experiencing breakthrough pain earlier in the placebo group. Conclusion. Preincision intravenous ketamine (0.25 mg/kg) offered 30-minute prolongation to postoperative analgesia requirement with reduced 24-hour pain scores. We recommend larger studies to explore this benefit. This trial is registered with Pan African Clinical Trial Registry number PACTR201404000807178.

    World Health Organization Surgical Safety Checklist: Compliance and Associated Surgical Outcomes in Uganda’s Referral Hospitals
    (Anesthesia & Analgesia, 2018) Igaga, Elizabeth N.; Sendagire, Cornelius; Kizito, Samuel; Obua, Daniel; Kwizera, Arthur
    A pilot study on the World Health Organization (WHO) Surgical Safety Checklist (SSC) showed a reduction in both major complications and mortality of surgical patients. Compliance with this checklist varies around the world. We aimed to determine the extent of compliance with the WHO SSC and its association with surgical outcomes in 5 of Uganda’s referral hospitals. METHODS: A multicentre prospective cohort study was conducted in 5 referral hospitals in Uganda. Using a questionnaire based on the WHO SSC, patients undergoing surgical operations were systematically recruited into the study from April 2016 to July 2016. The patients were followed up daily for 30 days or until discharge for the purpose of documentation of complications. Logistic regression and linear regression were used to assess for association between compliance and perioperative surgical outcomes. RESULTS: We recruited 859 patients into the study. Overall compliance with the WHO SSC was 41.7% (95% confidence interval [CI], 39.7–43.8) ranging from 11.9% to 89.8% across the different hospitals. Overall compliance with “sign in” was 44.7% (95% CI, 43–45.6), with “time out” was 42.0% (95% CI, 39.4–44.6), and with “sign out” was 33.3% (95% CI, 30.7–35.9). There was no association between compliance and perioperative surgical outcomes: length of hospital stay, adverse events, and mortality. CONCLUSIONS: This study revealed low levels of compliance with the WHO SSC. There was a statistically significant association between this level of compliance and the incidence of pain and loss of consciousness postoperatively.
