Regional anesthesia in resource-limited and disaster environments: a daring discourse

Area of Science:

• Anesthesiology and Perioperative Medicine
• Disaster Medicine and Emergency Preparedness
• Global Health and Resource-Limited Settings

Background:

• Regional anesthesia (RA) is a standard in well-resourced healthcare settings.
• RA presents unique advantages in resource-limited environments, such as disaster zones and wartime.
• Traditional anesthesia methods pose challenges in austere settings due to equipment and personnel limitations.

Purpose of the Study:

• To explore the potential and historical application of regional anesthesia in resource-limited environments.
• To highlight the benefits of RA over general anesthesia and opioid-based analgesia in austere settings.
• To assess the feasibility of ultrasound-guided RA with advancements in portable ultrasound technology.

Main Methods:

• Review of historical case examples of RA application in man-made and natural disaster scenarios.
• Discussion of the comparative benefits of RA versus general anesthesia and opioid analgesia.
• Analysis of the impact of decreasing ultrasound costs and increasing portability on RA accessibility.

Main Results:

• RA provides decreased complication risks, reduced need for mechanical ventilation, and improved cost-efficiency compared to general anesthesia.
• Ultrasound-guided RA is becoming more feasible in resource-limited settings due to technological advancements.
• Historical examples demonstrate the successful implementation of RA in extreme environments.

Conclusions:

• Regional anesthesia is a viable and beneficial anesthetic technique for resource-limited environments.
• Advancements in ultrasound technology enhance the accessibility and application of RA in austere settings.
• Further research is needed to optimize the utility and availability of RA in these critical situations.
