[Caesarean section to prevent supine hypotension syndrome]

Area of Science:

• Anesthesiology
• Obstetrics
• Pharmacology

Background:

• Investigating posture's effect on spinal anesthesia in cesarean sections.
• Evaluating a modified combined spinal epidural (CSE) technique.
• Utilizing lidocaine and isobaric bupivacaine for spinal anesthesia.

Purpose of the Study:

• To determine the impact of post-spinal anesthesia posture on parturients.
• To demonstrate the efficacy of a modified CSE method.
• To mitigate hypotension associated with spinal anesthesia.

Main Methods:

• Patients received either 2% lidocaine or 0.5% isobaric bupivacaine via spinal anesthesia.
• Groups were either immediately turned supine (S) or maintained in a left lateral position for 10-15 minutes (L) post-injection.
• All patients received an epidural injection 16 minutes after spinal anesthesia.

Main Results:

• A significant difference in the level of analgesia was observed between the supine and left lateral groups 10 minutes post-injection (P<0.05).
• Systolic blood pressure significantly decreased in the supine groups compared to pre-injection levels (P<0.05).

Conclusions:

• The modified CSE method effectively prevents hypotension during spinal anesthesia.
• Maintaining a left lateral position post-spinal anesthesia enhances analgesia.
• This technique offers beneficial effects for women undergoing cesarean sections.
