What are the essential considerations and protocols for managing surgical patients in a rural setting with limited resources?

Managing Surgical Patients in Rural Settings with Limited Resources

In rural settings with limited resources, prioritize a robust triage system using abdominal signs combined with early warning signs to identify patients requiring immediate surgical intervention, establish protocols for hemodynamic stabilization with available resources, ensure immediate availability of trained personnel and operating rooms for emergency cases, and develop clear transfer protocols to higher-level facilities for complex cases requiring resources beyond local capacity. 1

Essential Triage and Initial Assessment

Patient Screening Protocol

• Implement a combination of abdominal signs and symptoms with early warning signs to screen patients needing immediate acute care surgery 1
• Use clinical assessment as the primary diagnostic tool, supported by basic laboratory tests like complete blood count when imaging is unavailable 1
• Designate senior clinicians with expertise to promptly recognize whether surgery is required for initial assessment 1

Diagnostic Approach in Resource-Limited Settings

• Apply a tailored diagnostic step-up approach based on available hospital resources 1
• Utilize ultrasound and plain X-ray as primary diagnostic tools in remote areas where CT is unavailable 1
• Consider diagnostic peritoneal lavage (DPL) when CT scan or ultrasound is not promptly available, particularly in shocked patients with massive subcutaneous emphysema 1
• Perform Extended Focused Assessment with Sonography for Trauma (E-FAST) for rapid detection of intra-abdominal free fluid 2

Critical Resource Requirements

Minimum Essential Resources for Non-Operative Management

For patients with moderate to severe injuries being considered for non-operative management, the following must be immediately available 1:

• Trained surgeons available 24/7
• Operating room accessible within 30 minutes
• Continuous monitoring capability (ideally ICU or ER setting)
• Access to blood and blood products (PRBC, FFP, cryoprecipitate, platelets)
• System for rapid transfer to higher-level care facilities

Hemodynamic Stabilization Resources

• Ensure respiratory therapy and ventilator support available 24/7 3
• Maintain vasopressor availability (epinephrine, norepinephrine, or dopamine) for mean arterial pressure maintenance of 50-60 mmHg 4
• Stock tranexamic acid (TXA) and prothrombin complex concentrate (PCC) for hemorrhage control 3
• Establish fluid resuscitation protocols with careful attention to adequate intravascular volume 4

Surgical Decision-Making Algorithms

For Hemodynamically Stable Patients

• Pursue non-operative management in patients with hemodynamic stability, no evidence of associated injuries, negative serial physical examinations, and negative imaging/blood tests 1
• Perform serial clinical evaluations (physical exams and laboratory testing) to detect changes in clinical status 1, 2
• Consider conservative management for adhesive small bowel obstruction, non-complicated appendicitis, and complicated diverticulitis (Hinchey class 1 and 2) with IV antibiotics and percutaneous drainage 1

For Hemodynamically Unstable Patients

• Proceed immediately to operative management with primary surgical intention to control hemorrhage and bile leak 1, 2
• Restrict surgery to life-threatening emergencies: intestinal perforation/ischemia, loop obstruction, incarcerated hernia, bleeding unresponsive to conservative approaches 1
• Prefer open approach over laparoscopy in COVID-19 confirmed patients or when appropriate equipment and full PPE are unavailable 1
• Avoid major resections initially; consider only in subsequent operations for large areas of devitalized tissue 1, 2

Workforce and Training Considerations

Task Shifting Strategy

• Train non-physician clinicians (NPCs) to perform essential surgical procedures, as this represents the only viable option in areas with dire shortage of surgeons and anesthesiologists 5
• Ensure non-specialist health workers are properly supervised and their training programs carefully evaluated 1
• Provide continuing education to rural hospital doctors to strengthen trauma care at the district level 1
• Establish mechanisms for accreditation and coordination of training programs with objective outcome evaluations 1

Surgeon Qualifications

• Ensure board-certified general surgeons are available, with ATLS certification strongly recommended (though only 50-53% of small rural hospitals currently meet this standard) 3
• Prioritize broad-based general surgery training that includes primary care surgery skills and special needs fellowships 6
• Develop dedicated rural surgery training programs including rotations in rural settings, broad exposure to surgical specialties, endoscopy experience, and training without competing specialty learners 7

Perioperative Protocols

Prophylactic Antibiotic Administration

For contaminated or potentially contaminated surgery 8, 9:

• Administer cefazolin 1 gram IV 30-60 minutes prior to surgical incision
• Give intraoperative doses of 500 mg to 1 gram every 6-8 hours for lengthy procedures (≥2 hours)
• Continue postoperative dosing every 6-8 hours for 24 hours (may extend to 3-5 days for open-heart surgery or prosthetic arthroplasty)
• For colorectal surgery prophylaxis, administer metronidazole 15 mg/kg IV over 30-60 minutes completed one hour before surgery, followed by 7.5 mg/kg at 6 and 12 hours post-initial dose

Postoperative Care

• Initiate enteral feeding as soon as possible in the absence of contraindications 1, 2, 4
• Avoid severe protein restrictions; 60 grams per day is reasonable for most cases 4
• Start LMWH-based thromboprophylaxis as soon as possible following trauma 1, 2, 4
• Implement mechanical prophylaxis in all patients without absolute contraindications 1, 2
• Achieve early mobilization in stable patients 1, 2, 4

Transfer Protocols and Regionalization

Indications for Transfer

• Transfer patients requiring resources beyond local capacity, including those needing angiography/angioembolization, advanced imaging, or subspecialty surgical expertise 1
• Establish networking relationships with university tertiary care hospitals for complex case management 6
• Create regionalization of rural surgery centers with multiple surgeons to address lifestyle and workload issues 6

Pre-Transfer Stabilization

• Complete initial resuscitation and hemorrhage control measures before transfer 1
• Consider resuscitative endovascular balloon occlusion of the aorta (REBOA) as a bridge to definitive procedures during transfer 1, 2
• Ensure continuous monitoring during transport with appropriate personnel and equipment 1

Common Pitfalls to Avoid

• Delaying surgery while waiting for COVID-19 swab results when emergency surgery is deemed necessary; proceed with appropriate PPE 1
• Attempting laparoscopy without adequate smoke evacuation/filtration systems and full PPE, particularly in COVID-19 confirmed or unknown status patients 1
• Performing colorectal anastomosis in suspected or confirmed COVID-19 patients due to high complication risk and healthcare resource consumption 1
• Failing to establish clear protocols for rapid transfer to higher-level facilities when local resources are insufficient 1
• Inadequate attention to fluid resuscitation leading to hemodynamic instability; consider pulmonary artery catheterization in unstable patients 4
• Using intermittent dialysis modes instead of continuous modes when dialysis support is needed for acute renal failure 4

Infrastructure and Equipment Priorities

Essential Equipment (100% availability target) 3

• Computerized tomography scanner and ultrasound
• Certified operating rooms with emergency cardiovascular equipment
• Laboratory support available 24/7
• Blood bank with PRBC and FFP accessible 24/7
• Anesthesia availability 24/7 (currently only 78% of critical access hospitals meet this standard)

Recommended Additional Resources 3

• Operating room crew on call within 30 minutes
• Critical care nursing capability
• Biologic/synthetic mesh availability
• On-site pathology services when feasible
