Anesthetic Management of Nonobstetric Surgery during Pregnancy

Perioperative management of surgical procedure during pregnancy: a systematic review

Background

Approximately 1-2% of pregnant women undergo non-obstetric surgery under anaesthesia during their pregnancy. This review specifically targets anaesthesia management for pregnant women undergoing non-obstetric surgery in resource-limited settings.

Methods

Following the delineation of primary questions, scope, and inclusion criteria, a comprehensive search strategy utilizing advanced techniques was implemented across electronic sources, databases, and websites to identify relevant articles. A rigorous screening process was applied during the literature evaluation. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 statement guided the conduct of this review, ensuring adherence to standardized reporting practices.

Results

A total of 240 articles were initially identified from databases and websites. After screening titles and abstracts, 85 papers were excluded, and an additional 43 were removed due to duplication. Subsequently, 68 items were subjected to eligibility screening. Finally, 30 papers that specifically addressed anaesthetic considerations for pregnant women undergoing non-obstetric operations were reviewed.

Conclusion

Thorough preoperative evaluation is essential for all patients, with particular attention to modifications in anaesthetic management to accommodate physiological changes during pregnancy. Urgent and emergent surgeries should proceed promptly during pregnancy to optimize outcomes for both the mother and foetus. Maintaining uteroplacental perfusion generally involves avoiding maternal hypoxaemia, hypotension, hyper- and hypocapnia, temperature extremes, and stress. When deemed safe, regional anaesthesia may offer favourable outcomes for both the mother and foetus.

Middle-East obgyn graduate education (MOGGE) foundation practice guidelines: diagnostic approach to pregnancy of unknown location: practice guideline no. 03-O-21

Background

Pregnancy of unknown location (PUL) is a term used to describe failure of visualization of intrauterine or extrauterine gestational sac in a woman with a positive pregnancy test.

Body of the abstract

Ectopic pregnancy (EP) accounts for 1–2 % of all pregnancies. EP contributes to maternal mortality of a known cause by 4% in developed countries. However, case fatality rate may be 10 times higher in low-resource countries. This may be attributed to delayed diagnosis and lack of resources. PUL is a temporary term that may eventually lead to diagnosis of viable intrauterine pregnancy, pregnancy loss, or more seriously, EP.

Conclusion

This guideline appraises current evidence on assessment of PUL and early diagnosis of EP particularly in low-resource settings.
