RESUMO

OBJECTIVE: To evaluate the safety and effectiveness of a ketamine-based anesthesia package to support emergency cesarean section when no anesthetist is available. METHODS: A prospective case-series was conducted between December 11, 2013 and September 30, 2021 across nine sub-county hospitals in Kenya. Non-anesthetist healthcare providers undertook an evidence-based five-day training course. A structured instrument was used to collect preoperative, intraoperative, and postoperative data, and patients were contacted 6 months following the surgery to collect outcomes. The primary outcome measures were maternal and newborn survival and the ability of the ketamine package (ESM-Ketamine) to safely support cesarean deliveries. RESULTS: A total of 401 emergency cesarean sections were performed using ketamine, administered by 54 non-anesthetist providers. All mothers survived to discharge. Brief oxygen desaturations were recorded among 33 (8.2%) mothers, and agitation and hallucinations occurred among 13 (3.2%). There were no maternal serious adverse events. At 6-month follow-up, 94.2% of mothers who could be reached reported no complaints. Additionally, 402 (92.4%) of the 435 operative births survived to discharge. CONCLUSION: The ESM-Ketamine package can be used by trained non-anesthetist providers to support emergency cesarean sections when no anesthetist is available. Ketamine has significant potential to increase access to emergency cesarean deliveries in resource-limited settings.

RESUMO

INTRODUCTION: Five of the 7.2 billion people on earth have limited access to emergency and essential surgical procedures. The lack of safe, affordable and timely anaesthesia services are primary barriers to universal surgical coverage. The objective of this study was to assess intraoperative awareness when the 'Every Second Matters for Emergency and Essential Surgery - Ketamine' (ESM-Ketamine) package was used to support emergency and essential surgeries and painful procedures in rural Kenya when no anaesthetist was available. METHODS: Forty-seven consecutive adult patients that underwent an operative procedure under ESM-Ketamine at Sagam Community Hospital in Luanda, Kenya were enrolled. Participants underwent two semi-structured interviews that explored the patient's experience with ESM-Ketamine both after the operative procedure and four to six weeks after surgery. RESULTS: Forty-seven participants completed the first interview and 37 (78.7%) the second interview. Thirty-seven (78.7%) cases were procedural sedations and ten were (21.3%) emergency surgeries. Intraoperative awareness occurred in nine (24.3%) participants who underwent procedural sedation and two (20%) who underwent emergency surgery. Twenty-six (55.3%) participants reported dreams during the procedure. Thirty-two (86.5%) participants considered their experience positive, and 35 (95%) would recommend a procedure supported by ketamine to a friend. DISCUSSION: Most patients whose painful procedures and emergency operations were supported by the ESM-Ketamine package when no anaesthetist was available reported favourable experiences.

RESUMO

The objective was to assess the feasibility and safety of the ̳Every Second Matters for Emergency and Essential Surgery - Ketamine' (ESM-Ketamine) package in support of obstetric and gynecologic emergency and essential surgery when no anesthetist is available. A consecutive case series was conducted in twelve hospitals across five severely resource-limited counties in Kenya. 530 women underwent obstetric or gynecological operative procedures supported by non-anesthetist clinicians using the ESM-Ketamine package between November 1, 2013 and September 30, 2017. Main outcomes included reasons for ESM-Ketamine activations and ketamine-related adverse events. There were two (0.4%) prolonged (>30 seconds) oxygen desaturations below 92%. Brief oxygen desaturations (<30 seconds) below 92% occurred in 15 (2.8%) cases and 113 (21.3%) were administered diazepam to treat hallucinations or agitation. There were no ketamine-related deaths or injuries. The ESM- Ketamine package appears feasible and safe for use in support of obstetric and gynecologic surgeries when no anesthetist is available.

RESUMO

BACKGROUND: Postpartum hemorrhage is the most common cause of maternal deaths worldwide, the majority of which occur in low-resource settings. Uterine balloon tamponade (UBT) is an effective method of addressing uncontrolled postpartum hemorrhage (PPH) from uterine atony; however, UBT devices are often not affordable. We report on three novel uses of an ultra-low-cost condom uterine balloon tamponade (ESM-UBT) device. CASES: ESM-UBT devices were used in innovative ways to arrest severe uncontrolled pregnancy-related hemorrhage among three women in India and Tanzania. The first had sustained deep vaginal lacerations, the second a cervical pregnancy, and the third a complete molar pregnancy. CONCLUSION: The ESM-UBT device may be useful for control of obstetric hemorrhage caused by complex vaginal tears as well as cervical and molar pregnancies.

RESUMO

BACKGROUND: Lack of access to emergency and essential surgery is widespread in low- and middle-income countries. Scarce anesthesia services contribute to this unmet need. The aim of this study was to evaluate the safety and feasibility of the Every Second Matters for Emergency and Essential Surgery-Ketamine (ESM-Ketamine) package for emergency and essential procedures when no anesthetist was available. METHODS: From November 2013 to September 2017, the ESM-Ketamine package was used for patients requiring emergency or life-improving surgeries in fifteen selected facilities across Kenya when no anesthetist was available. A mixed-methods approach was used to assess safety and feasibility of the ESM-Ketamine package, including demand, acceptability, and practicality. The primary outcome was ketamine-related adverse events. Key-informant interviews captured perceptions of providers, hospital administrators, and surgeons/proceduralists. RESULTS: Non-anesthetist mid-level providers used ESM-Ketamine for 1216 surgical procedures across the fifteen study facilities. The median ketamine dose was 2.1 mg/kg. Brief (<30 s) oxygen desaturations occurred in 39 patients (3%), and prolonged (>30 s) oxygen desaturations occurred in seven patients (0.6%). There were 157 (13%) reported cases of hallucinations and agitation which were treated with diazepam. All patients recovered uneventfully, and no ketamine-related deaths were reported. Twenty-seven key-informant interviews showed strong support for the program with four main themes: financial considerations, provision of services, staff impact, and scaling considerations. CONCLUSIONS: The ESM-Ketamine package appears safe and feasible and is capable of expanding access to emergency and essential surgeries in rural Kenya when no anesthetist is available.

RESUMO

BACKGROUND: The need for palliative care services is rapidly increasing due to the rising number of patients with non-communicable diseases. The objective of this study was to assess the current availability and barriers to palliative care and healthcare worker knowledge and perceptions on palliative pain control in western Kenya. METHODS: An evidence-based 40-question assessment tool was conducted between October 2015 and February 2016 in Siaya County, western Kenya. All level 4 and 5 facilities (e.g., regional and district hospitals) were assessed, as well as a selection of lower-level facilities chosen via convenience sampling, stratified by facility level (e.g., dispensaries, health centers, and health clinics). RESULTS: A key informant at each of 22 facilities was surveyed and included 1 medical officer (5%), 12 clinical officers (55%), and 9 nurses (41%). Key themes included training and education, awareness of palliative care and hospice, services provided, and pain control. All 22 providers had heard of palliative care and 4 (18%) had received formal training. Fourteen (64%) providers knew that morphine was on the World Health Organization (WHO) essential medication list, 8 (36%) had previously prescribed opioids, and 5 (23%) had prescribed them for palliation. Provider concerns for opioid use included its addictive properties (59%), appropriate dosing (9%), cost (5%), side effects (9%), and availability (5%). CONCLUSIONS: Palliative care and hospice services were identified by providers as important components in the management of chronic illnesses in western Kenya. Further provider education as well as increased access to pain medications including opioids is necessary to improve the care of patients in western Kenya.

RESUMO

OBJECTIVE: To assess the safety of a ketamine-based rescue anesthesia package to support emergency cesarean delivery and emergency laparotomy when no anesthetist was available. METHODS: A prospective case-series study was conducted at seven sub-county hospitals in western Kenya between December 10, 2013, and January 20, 2016. Non-anesthetist clinicians underwent 5days of training in the Every Second Matters-Ketamine (ESM-Ketamine) program. A database captured preoperative, intraoperative, and postoperative details of all surgeries in which ESM-Ketamine was used. The primary outcome measure was the ability of ESM-Ketamine to safely support emergency operative procedures. RESULTS: Non-anesthetist providers trained on ESM-Ketamine supported 83 emergency cesarean deliveries and 26 emergency laparotomies. Ketamine was administered by 10 nurse-midwives and six clinical officers. Brief oxygen desaturations (<92% for <30s) were recorded among 5 (4.6%) of the 109 patients. Hallucinations occurred among 9 (8.3%) patients. No serious adverse events related to the use of ESM-Ketamine were recorded. CONCLUSION: The ESM-Ketamine package can be safely used by trained non-anesthetist providers to support emergency cesarean delivery and emergency laparotomy when no anesthetist is available.

RESUMO

Delivering therapeutics deep into damaged tissue during bleeding is challenging because of the outward flow of blood. When coagulants cannot reach and clot blood at its source, uncontrolled bleeding can occur and increase surgical complications and fatalities. Self-propelling particles have been proposed as a strategy for transporting agents upstream through blood. Many nanoparticle and microparticle systems exhibiting autonomous or collective movement have been developed, but propulsion has not been used successfully in blood or used in vivo to transport therapeutics. We show that simple gas-generating microparticles consisting of carbonate and tranexamic acid traveled through aqueous solutions at velocities of up to 1.5 cm/s and delivered therapeutics millimeters into the vasculature of wounds. The particles transported themselves through a combination of lateral propulsion, buoyant rise, and convection. When loaded with active thrombin, these particles worked effectively as a hemostatic agent and halted severe hemorrhage in multiple animal models of intraoperative and traumatic bleeding. Many medical applications have been suggested for self-propelling particles, and the findings of this study show that the active self-fueled transport of particles can function in vivo to enhance drug delivery.
