RESUMEN
BACKGROUND: The efficacy of postoperative nausea and vomiting (PONV) prevention protocols in low-income countries is not well known. Different surgical procedures, available medications, and co-occurring diseases imply that existing protocols may need validation in these settings. We assessed the association of a risk-directed PONV prevention protocol on the incidence of PONV and short-term surgical outcomes in a teaching hospital in Rwanda. METHODS: We compared the incidence of PONV during the first 48 hours postoperatively before (April 1, 2019-June 30, 2019; preintervention) and immediately after (July 1, 2019-September 30, 2019; postintervention) implementing an Apfel score-based PONV prevention strategy in 116 adult patients undergoing elective open abdominal surgery at Kigali University Teaching Hospital in Rwanda. Secondary outcomes included time to first oral intake, hospital length of stay, and rate of wound dehiscence. Interrupted time series analyses were performed to assess the associated temporal slopes of the outcome before and immediately after implementation of the risk-directed PONV prevention protocol. RESULTS: Compared to just before the intervention, there was no change in the odds of PONV at the beginning of the postintervention period (odds ratio [OR], 0.23; 95% confidence interval [CI], 0.05-1.01). There was a decreasing trend in the odds of nausea (OR, 0.60; 95% CI, 0.36-0.97) per month. However, there was no difference in the incidence of nausea immediately after implementation of the protocol (OR, 0.96; 95% CI, 0.25-3.72) or in the slope between preintervention and postintervention periods (OR, 1.48; 95% CI, 0.60-3.65). In contrast, there was no change in the odds of vomiting during the preintervention period (OR, 1.01; 95% CI, 0.61-1.67) per month. The odds of vomiting decreased at the beginning of the postintervention period compared to just before (OR, 0.10; 95% CI, 0.02-0.47; P = .004). Finally, there was a significant decrease in the average time to first oral intake (estimated 14 hours less; 95% CI, -25 to -3) when the protocol was first implemented, after adjusting for confounders; however, there was no difference in the slope of the average time to first oral intake between the 2 periods ( P = .44). CONCLUSIONS: A risk-directed PONV prophylaxis protocol was associated with reduced vomiting and time to first oral intake after implementation. There was no substantial difference in the slopes of vomiting incidence and time to first oral intake before and after implementation.

BACKGROUND: There is little information about the current management of pain after obstetric surgery at Mulago hospital in Uganda, one of the largest hospitals in Africa with approximately 32,000 deliveries per year. The primary goal of this study was to assess the severity of post cesarean section pain. Secondary objectives were to identify analgesic medications used to control post cesarean section pain and resultant patient satisfaction. METHODS: We prospectively followed 333 women who underwent cesarean section under spinal anesthesia. Subjective assessment of the participants' pain was done using the Visual Analogue Scale (0 to 100) at 0, 6 and 24 h after surgery. Satisfaction with pain control was ascertained at 24 h after surgery using a 2-point scale (yes/no). Participants' charts were reviewed for records of analgesics administered. RESULTS: Pain control medications used in the first 24 h following cesarean section at this hospital included diclofenac only, pethidine only, tramadol only and multiple pain medications. There were mothers who did not receive any analgesic medication. The highest pain scores were reported at 6 h (median: 37; (IQR:37.5). 68% of participants reported they were satisfied with their pain control. CONCLUSION: Adequate management of post-cesarean section pain remains a challenge at Mulago hospital. Greater inter-professional collaboration, self-administered analgesia, scheduled prescription orders and increasing availability of analgesic drugs may contribute to improved treatment of postoperative pain with better pain scores.

BACKGROUND: Delay in receiving care significantly contributes to maternal morbidity and mortality. Much has been studied about reducing delays prior to arrival to referral facilities, but the delays incurred upon arrival to the hospital have not been described in many low- and middle-income countries. METHODS: We report on the obstetric referral process at Ridge Regional Hospital, Accra, Ghana, the largest referral hospital in the Ghana Health System. This study uses data from a prospectively-collected cohort of 1082 women presenting with pregnancy complications over a 10-week period. To characterize which factors lead to delays in receiving care, we analyzed wait times based on reason for referral, time and day of arrival, and concurrent volume of patients in the triage area. RESULTS: The findings show that 108 facilities refer patients to Ridge Regional Hospital, and 52 facilities account for 90.5% of all transfers. The most common reason for referral was fetal-pelvic size disproportion (24.3%) followed by hypertensive disorders of pregnancy (9.8%) and prior uterine scar (9.1%). The median arrival-to-evaluation (wait) time was 40 min (IQR 15-100); 206 (22%) of women were evaluated within 10 min of arrival. Factors associated with longer wait times include presenting during the night shift, being in latent labour, and having a non-time-sensitive risk factor. The median time to be evaluated was 32 min (12-80) for women with hypertensive disorders of pregnancy and 37 min (10-66) for women with obstetric hemorrhage. In addition, the wait time for women in the second stage of labour was 30 min (12-79). CONCLUSIONS: Reducing delay upon arrival is imperative to improve the care at high-volume comprehensive emergency obstetric centers. Although women with time-sensitive risk factors such as hypertension, bleeding, fever, and second stage of labour were seen more quickly than the baseline population, all groups failed to be evaluated within the international standard of 10 min. This study emphasizes the need to improve hospital systems so that space and personnel are available to access high-risk pregnancy transfers rapidly.

BACKGROUND: The unimodal approach of using pentazocine as post-cesarean section pain relief is inadequate, hence the need for a safer, easily available and more effective multimodal approach. AIM: To evaluate the effectiveness of rectal diclofenac combined with intramuscular pentazocine for postoperative pain following cesarean section. METHODS: In this double blind clinical trial, 130 pregnant women scheduled for cesarean section under spinal anesthesia were randomly assigned to two groups. Group A received 100mg diclofenac suppository and group B received placebo suppository immediately following surgery, 12 and 24h later. Both groups also received intramuscular pentazocine 30mg immediately following surgery and 6 hourly postoperatively in the first 24 h. Postoperative pain was assessed by visual analogue scale at end of surgery and 2, 12 and 24 h after surgery. Patient satisfaction scores were also assessed. RESULTS: One hundred and sixteen patients completed the study. Combining diclofenac and pentazocine had statistically significant reduction in pain intensity at 2, 12, and 24 hours postoperatively compared to pentazocine alone (p <0.05). No significant side effects were noted in both groups. The combined group also had significantly better patient satisfaction scores. CONCLUSION: The addition of diclofenac suppository to intramuscular pentazocine provides better pain relief after cesarean section and increased patient satisfaction.

Anesthesia providers in low-income countries may infrequently provide regional anesthesia techniques for obstetrics due to insufficient training and supplies, limited manpower, and a lack of perceived need. In 2007, Kybele, Inc. began a 5-year collaboration in Ghana to improve obstetric anesthesia services. A program was designed to teach spinal anesthesia for cesarean delivery and spinal labor analgesia at Ridge Regional Hospital, Accra, the second largest obstetric unit in Ghana. The use of spinal anesthesia for cesarean delivery increased significantly from 6% in 2006 to 89% in 2009. By 2012, >90% of cesarean deliveries were conducted with spinal anesthesia, despite a doubling of the number performed. A trial of spinal labor analgesia was assessed in a small cohort of parturients with minimal complications; however, protocol deviations were observed. Although subsequent efforts to provide spinal analgesia in the labor ward were hampered by anesthesia provider shortages, spinal anesthesia for cesarean delivery proved to be practical and sustainable.

Dural puncture following neuraxial anesthesia can cause persistent cerebrospinal fluid leakage. A 35-year-old, 39-week gestation healthy parturient underwent cesarean delivery under spinal anesthesia. Spinal anesthesia was performed using a 25-gauge Quincke needle. Despite the occurrence of postoperative positional headache and neck pain, she was discharged home. Two weeks following discharge, she developed seizures and deteriorating level of consciousness. Brain computerized tomography scan revealed massive left subdural hematoma. She died 3 days later. We discuss awareness of neuraxial complication among maternity staff, effective follow-up, and available management strategy in low-resource settings. Persistent headache following neuraxial anesthesia should be investigated.

A term baby was delivered by cesarean and found to have an unexpected large teratoma attached to its mouth. Surgical excision was planned within 24 hours. Anesthesia concern of airway control required multidisciplinary team consultation, airway and patient preparation, and anticipation for failure. Challenging airway cases in low-resource countries can be successfully managed with deliberate attention to detail, preparation, and experience.

The Episure AutoDetect syringe, a spring-loaded syringe, is a new loss-of-resistance syringe with an internal compression spring that applies constant pressure on the plunger. In this pilot study, we compared the spring-loaded syringe with the standard glass syringe for identification of the epidural space during initiation of epidural analgesia in parturients. The primary outcome was the incidence of failed epidural analgesia. Three-hundred and twenty-five women were enrolled. Eight residents performed 291 procedures (90%) and two attendings performed 34 procedures (10%). Epidural analgesia failed in five subjects in the glass syringe group and in no subject in the spring-loaded syringe group (P = 0.025).

OBJECTIVE: To evaluate the cost-effectiveness of a quality improvement intervention aimed at reducing maternal and fetal mortality in Accra, Ghana. DESIGN: Quasi-experimental, time-sequence intervention, retrospective cost-effectiveness analysis. METHODS: Data were collected on the cost and outcomes of a 5-year Kybele-Ghana Health Service Quality Improvement (QI) intervention conducted at Ridge Regional Hospital, a tertiary referral center in Accra, Ghana, focused on systems, personnel, and communication. Maternal deaths prevented were estimated comparing observed rates with counterfactual projections of maternal mortality and case-fatality rates for hypertensive disorders of pregnancy and obstetric hemorrhage. Stillbirths prevented were estimated based on counterfactual estimates of stillbirth rates. Cost-effectiveness was then calculated using estimated disability-adjusted life years averted and subjected to Monte Carlo and one-way sensitivity analyses to test the importance of assumptions inherent in the calculations. MAIN OUTCOME MEASURE: Incremental Cost-effectiveness ratio (ICER), which represents the cost per disability-adjusted life-year (DALY) averted by the intervention compared to a model counterfactual. RESULTS: From 2007-2011, 39,234 deliveries were affected by the QI intervention implemented at Ridge Regional Hospital. The total budget for the program was $2,363,100. Based on program estimates, 236 (±5) maternal deaths and 129 (±13) intrapartum stillbirths were averted (14,876 DALYs), implying an ICER of $158 ($129-$195) USD. This value is well below the highly cost-effective threshold of $1268 USD. Sensitivity analysis considered DALY calculation methods, and yearly prevalence of risk factors and case fatality rates. In each of these analyses, the program remained highly cost-effective with an ICER ranging from $97-$218. CONCLUSION: QI interventions to reduce maternal and fetal mortality in low resource settings can be highly cost effective. Cost-effectiveness analysis is feasible and should regularly be conducted to encourage fiscal responsibility in the pursuit of improved maternal and child health.

Ghana, like other countries in sub-Saharan African, has limited access to surgery. One contributing factor is the inadequate number of anesthesia providers. To address this need, Kybele, Inc., a US-based non-governmental organization, partnered with the Ghana Health Service to establish the third nurse anesthesia training school (NATS) in Ghana. The school, based at Ridge Regional Hospital (RRH) in Accra, opened in October 2009. This paper describes the evolution of the training program and presents the curriculum. Second, the results of a voluntary survey conducted among the first four classes of graduates (2011-2014) are presented to determine their perceived strengths and gaps in training and to identify employment locations and equipment availability. Seventy-five of 93 graduates (81%) responded to the survey. The graduates reported working in 39 hospitals across 7 of the 10 regions in Ghana. Six providers (8%) worked alone and 16 (21%) were one of only two providers. Fifty-three providers (71%) had no physician anesthesiologist at their facility. Most providers had access to basic anesthesia equipment; however, there was limited access to emergency airway equipment. While most graduates felt that their training had prepared them for their current positions, 21% reported experiencing a patient death during anesthesia. The NATS at RRH has been sustained and most of the graduates are working in Ghana, filling an important void. Quality improvement and continuing education must be emphasized in an effort to reduce surgical morbidity and mortality in Ghana.
RESUMEN
OBJECTIVE: To evaluate the performance of a continuous quality improvement collaboration at Ridge Regional Hospital, Accra, Ghana, that aimed to halve maternal and neonatal deaths. METHODS: In a quasi-experimental, pre- and post-intervention analysis, system deficiencies were analyzed and 97 improvement activities were implemented from January 2007 to December 2011. Data were collected on outcomes and implementation rates of improvement activities. Severity-adjustment models were used to calculate counterfactual mortality ratios. Regression analysis was used to determine the association between improvement activities, staffing, and maternal mortality. RESULTS: Maternal mortality decreased by 22.4% between 2007 and 2011, from 496 to 385 per 100000 deliveries, despite a 50% increase in deliveries and five- and three-fold increases in the proportion of pregnancies complicated by obstetric hemorrhage and hypertensive disorders of pregnancy, respectively. Case fatality rates for obstetric hemorrhage and hypertensive disorders of pregnancy decreased from 14.8% to 1.6% and 3.1% to 1.1%, respectively. The mean implementation score was 68% for the 97 improvement processes. Overall, 43 maternal deaths were prevented by the intervention; however, risk severity-adjustment models indicated that an even greater number of deaths was averted. Mortality reduction was correlated with 26 continuous quality improvement activities, and with the number of anesthesia nurses and labor midwives. CONCLUSION: The implementation of quality improvement activities was closely correlated with improved maternal mortality.

OBJECTIVE: To assess the impact of intraoperative dexmedetomidine infusion on postoperative analgesia in women undergoing major open and laparoscopic gynecologic surgery under general anesthesia. RESEARCH DESIGN AND METHODS: A retrospective analysis of patients who underwent major open and laparoscopic gynecologic surgery under general anesthesia from January 2007 to October 2008. Patients who received intraoperative opioids with a dexmedetomidine infusion were compared to those who received opioids alone. Patients who received regional anesthesia, remifentanil, or other analgesic adjuncts were excluded. Data were collected in the postanesthesia care unit (PACU) for all patients, and for 24 hours in the open group. RESULTS: A total of 580 women were included in the analysis (293 open surgery [103 dexmedetomidine, 190 controls] and 287 laparoscopic surgery [101 dexmedetomidine, 186 controls]). In the open group, patients who received dexmedetomidine required less opioids intraoperatively and in PACU. However, there was no difference in the duration of PACU stay, opioid consumption from PACU discharge to 24 h or in the need for rescue antiemetics. Pain scores were not different in PACU. In the laparoscopic group, there was no difference between the groups in intraoperative or PACU opioids, pain scores, or need for rescue antiemetics. Patients in the dexmedetomidine laparoscopic group needed less inhaled agents intraoperatively, but stayed longer in PACU. CONCLUSIONS: Intraoperative dexmedetomidine infusion provided an opioid sparing effect intraoperatively and in PACU in women undergoing open gynecologic surgery but did not reduce the need for rescue antiemetics or the duration of PACU stay and did not provide any benefit beyond PACU discharge. For laparoscopic surgery, dexmedetomidine infusion did not provide any analgesic benefit. Limitations of the study include its retrospective non-randomized nature, absence of strict protocol for dexmedetomidine administration and lack of data beyond PACU discharge in patients having laparoscopic surgery.

PURPOSE: To describe the anesthetic and peripartum management of a parturient with paroxysmal nocturnal hemoglobinuria complicated by severe preeclampsia, review the pathophysiology of this condition, rationale for thromboembolic prophylaxis, and its implications on the choice of labour analgesia and anesthesia. CLINICAL FEATURES: A 35-yr-old primigravida was diagnosed with paroxysmal nocturnal hemoglobinuria at 18 weeks gestation following new onset pancytopenia. Venous thromboembolic prophylaxis with low molecular weight heparin (LMWH) was started, and continued despite a persistent thrombocytopenia. At 34 weeks, labour was induced after she developed signs of severe preeclampsia, and intravenous magnesium sulfate therapy was commenced. The use of a twice daily dosing regime of LMWH, along with severe thrombocytopenia contraindicated neuraxial anesthesia. As a result, labour analgesia was provided with an intravenous patient-controlled analgesia system with fentanyl. The patient subsequently had an uneventful Cesarean delivery under general anesthesia. Anticoagulation with LMWH was restarted postoperatively, and continued for six weeks postpartum. She was discharged home on day 20 postpartum, on oral prednisolone under the care of the hematologists. CONCLUSION: Paroxysmal nocturnal hemoglobinuria is associated with an increased risk of venous thromboembolism, and so anticoagulation therapy assumes primary importance. The use of LMWH for prophylaxis in combination with thrombocytopenia may contraindicate neuraxial anesthesia. General anesthesia should be aimed at preventing or exacerbating complement mediated intravascular hemolysis.

Postpartum bilateral tubal ligation (PPBTL) causes postoperative pain. We designed this study to determine the efficacy of 50 microg intrathecal morphine for analgesia after PPBTL. Sixty-five women received spinal anesthesia with 12.75 mg hyperbaric bupivacaine, 20 microg of fentanyl, and either 50 microg of morphine (morphine group) or 0.05 mL of saline (control group). Postoperative analgesia was provided with regular naproxen 500 mg and oxycodone 5 mg/acetaminophen 325 mg mixture as needed. Overall, satisfaction was higher (P=0.003) and pain was less intense at rest (P=0.008) and on movement (P <0.0001) in the morphine group. There was no significant overall difference in nausea, pruritus, or sedation scores, but vomiting occurred more frequently in the morphine group (21.4% versus 3.5%; P=0.052). In post hoc comparisons, pain at rest within the morphine group was significantly less at 4 h (P=0.006), pain on movement was significantly less at 4 h (P=0.002) and 12 h (P=0.0004), and pruritus was significantly more frequent at 12 h (P=0.002) compared with the control group. Oxycodone 5 mg/acetaminophen 325 mg mixture consumption was significantly smaller (P=0.006) and the time to first request of analgesia was significantly longer (P=0.006) in the morphine group. We conclude that the addition of 50 microg of morphine to intrathecal hyperbaric bupivacaine and fentanyl provides improved postoperative analgesia in women undergoing PPBTL.

PURPOSE: To examine if ilioinguinal-iliohypogastric nerve block could reduce the need for post-Cesarean delivery morphine analgesia and thus reduce the incidence of opioid related adverse-effects. METHODS: A multi-level technique for performing the nerve block with bupivacaine was developed and then utilized in this two-part study. Part one was a retrospective assessment of Cesarean delivery patients with and without ilioinguinal-iliohypogastric blocks to determine if the technique reduced patient controlled analgesia morphine use and thus would warrant further study. The second phase was a randomized double-blind placebo-controlled trial to compare post-Cesarean morphine use and the appearance of opioid-related side effects between the anesthetic and placebo-injected groups. RESULTS: Both phases demonstrated that our method of ilioinguinal-iliohypogastric nerve block significantly reduced the amount of iv morphine used by patients during the 24 hr following Cesarean delivery. In the retrospective assessment, morphine use was 49 +/- 30 mg in the block group vs 79 +/- 25 mg in the no block group (P = 0.0063). For the prospective trial, patients who received nerve blocks with bupivacaine had a similar result, self-administering 48 +/- 27 mg of morphine over 24 hr compared to 67 +/- 28 mg administered by patients who received infiltrations of saline. However, despite the significant decrease in morphine use, there was no reduction in opioid-related adverse effects: the incidences of nausea were 41% and 46% (P = 0.70) and for itching were 79% and 63% (P = 0.25) in the placebo and nerve block groups, respectively. CONCLUSION: A multi-level ilioinguinal-iliohypogastric nerve block technique can reduce the amount of systemic morphine required to control post-Cesarean delivery pain but this reduction was not associated with a reduction of opioid related adverse effects in our study group.
