Enteral Resuscitation Nepal (Pilot Study)

Phase 3

Completed

Conditions: Burn Body Region Unspecified
Burn Shock

Interventions: Drug: Oral Rehydration Solution
Drug: Lactated Ringer

Registration Number: NCT04732624

Lead Sponsor: University of Washington

Brief Summary: Nepal and the South Asian sub-continent carry some of the highest rates of burn injury globally, with an associated high morbidity and mortality. Nepal currently has one major center equipped for burn care, in Kirtipur, Nepal and receives referred patients from around the country. At presentation, most patients with major burns have had minimal to no resuscitation on arrival, often hours to days after the burn injury was sustained.

Timely fluid resuscitation, initiated as soon as possible after major burn injury, is the main tenet of acute burn care. Lack of adequate resuscitation in major burn injuries leads to kidney injury, progression of burn injury, sepsis, burn shock, and death. The current standard of care for major burn resuscitation is intravenous fluid resuscitation. In Nepal, however, adequately trained and equipped hospitals for treatment of burn care are not available (for a variety of reasons). Additionally, there is not a systematic emergency medical transport system available for provision of medical care and resuscitation during transport. Enteral-based resuscitation with substances like the WHO Oral Rehydration Solution (ORS) is recommended by burn experts and the professional burn societies when resources and access to intravenous fluid resuscitation are not available in resource-constrained settings such as rural areas, low- and middle-income countries, and military battlefield scenarios. Studies have previously demonstrated the efficacy and safety of enteral-based resuscitation in controlled, high-resource settings, however there have not been real-world effectiveness trials in austere settings. Therefore, the investigators seek to ultimately address the problem of pre-hospital and pre-burn center admission resuscitation by studying the feasibility and effectiveness of enteral resuscitation with Oral Rehydration Solution (ORS) in preventing burn shock.

This study examines enteral (oral)-based resuscitation with ORS and IV Fluids versus only IV Fluids for the treatment of major burn injuries. The intervention portion of the study will entail randomization of patients presenting with acute burn injuries of 20-40% total body surface area (TBSA) to an enteral-based resuscitation versus the standard of care IV fluid resuscitation. The intervention will continue through the 24-72 hours of the acute resuscitation period.

This is a feasibility study, primarily to develop and establish the research infrastructure and practices at the study site for future pilot study and eventually randomized-controlled trial research on this intervention. The primary outcomes will be measures of feasibility such as the adherence rate to the resuscitation protocols. Further, there will be a qualitative component to the study with focus group interviews of the bedside healthcare providers (doctors and nurses) who are caring for the enrolled patients, in order to understand the challenges and facilitators of enteral resuscitation. Qualitative analysis will be done to understand the major themes of challenges and facilitators to enteral resuscitation.

Arm && Interventions

Group	Intervention	Description
Enteral-based Protocolized Resuscitation	Oral Rehydration Solution	Administration of Enteral-based Resuscitation using Oral Rehydration Solution (ORS) either by mouth of via naso-enteric access for moderate sized burn injuries (20-40% TBSA) per resuscitation protocol for burn-injured patients. Resuscitation will be administered in the acute resuscitation phase of burn injury (24-72 hours post injury). Patients will receive supplemental Intravenous Fluid (IV Fluid) resuscitation using Lactated Ringer's solution as needed per protocol.
Enteral-based Protocolized Resuscitation	Lactated Ringer	Administration of Enteral-based Resuscitation using Oral Rehydration Solution (ORS) either by mouth of via naso-enteric access for moderate sized burn injuries (20-40% TBSA) per resuscitation protocol for burn-injured patients. Resuscitation will be administered in the acute resuscitation phase of burn injury (24-72 hours post injury). Patients will receive supplemental Intravenous Fluid (IV Fluid) resuscitation using Lactated Ringer's solution as needed per protocol.
Intravenous Fluid Protocolized Resuscitation	Lactated Ringer	Administration of Intravenous Fluid using Lactated Ringer's solution per standard of care resuscitation protocol for patients with moderate sized burn injuries (20-40% TBSA).

Primary Outcome Measures

Name	Time	Method
24 Hour Average Urine Output (UOP)	24 hours	Calculated by totaling all of the recorded urine output (adding up the columns labelled HR 1-2 UO, HR 3-4 UO, etc. until HR 23-24), then dividing by their weight in Kg (column labelled Admission weight) and dividing by 24 hours. The units of this measurement will be mL/kg/hr.
24-hour Resuscitation Volume	24 hours	Calculated by totaling the total resuscitative fluids administered in first 24 hours of resuscitation, divided by admission weight and % TBSA of burn injury. (cc/kg/% TBSA of burn injury)
Hours From Injury to Resuscitation	Point measurement (Once at the start of resuscitation)	Hours calculated from point of injury to starting of resuscitation.

Secondary Outcome Measures

Name	Time	Method
Participants Death Within 72 Hours of Resuscitation	72 hours	Secondary resuscitation outcome measured daily within study period i.e. 72 hours of resuscitation as participant death related or associated with the study. Monitored by data safety monitoring board and if proven to be associated with the study considered serious adverse event.
Discharge Outcome	Measured over complete course of hospitalization until discharge or death, assessed every 24 hours after enrollment in the study. Maximum timeframe 6 months.	Outcome of hospital stay
Number of Participants With GI Discomfort	24 hours	Any "check" for nausea, vomiting, distention, diarrhea
Number of Participants Crossover to IV Due to GI Intolerance	24hours	Number of participants crossover to standard of care (IV resuscitation) due to GI intolerance like nausea, vomitting
Number of Participants With Acute Kidney Injury	72 hours	Measured with any signs of Acute Kidney injury during first 72 hours of resuscitation according to KDIGO definition i.e., increase in serum creatinine by 0.3mg/dL or more within 48 hours or increase in serum creatinine to 1.5 times baseline or more within the last 7 days or urine output less than 0.5 mL/kg/h for 6 hours. AKI on admission was defined as a serum creatinine greater than 1.5 mg/dL with less than 0.5 mL/kg/h of urine output for the first hour. Urine output was measured every 2 hours for the first 24 hours and serum creatinine was measured on admission then 8,16,24,48 and 72 hours from the commencement of the resuscitation.
