Spinal anaesthesia for caesarean section in the Solomon Islands

Area of Science:

• Obstetrics and Gynecology
• Anesthesiology
• Global Health

Background:

• Caesarean sections are common globally, requiring safe and effective anesthesia.
• Developing tropical countries face unique challenges in providing advanced medical care.
• Spinal anesthesia is a preferred method for caesarean sections due to its efficacy and safety profile.

Purpose of the Study:

• To evaluate the safety and efficacy of spinal anesthesia for caesarean sections in the Solomon Islands.
• To assess the incidence of hypotension and spinal headaches in this specific population.
• To determine the feasibility of this anesthetic technique in a resource-limited tropical environment.

Main Methods:

• A retrospective review of 43 spinal anesthetics administered for caesarean sections.
• Utilized a 25-gauge Quincke needle for spinal anesthesia.
• Administered either heavy bupivacaine 0.5% (2.5 ml) or plain bupivacaine 0.5% (2.0-2.5 ml).

Main Results:

• Four patients (9.3%) experienced hypotension, with a minimum recorded pressure of 85 mmHg.
• No cases of post-dural puncture headache (spinal headache) were reported.
• Five patients (11.6%) required conversion to general anesthesia.

Conclusions:

• Spinal anesthesia with bupivacaine is a viable and safe option for caesarean sections in the Solomon Islands.
• The technique demonstrated a low incidence of adverse events, particularly spinal headaches.
• This method is recommended for obstetric anesthesia in similar resource-limited tropical settings in the Pacific Islands.
