Comparison of preoperative gastric contents and serum gastrin concentrations in pregnant and nonpregnant women

Comparison Of Gastric PH In Emergency Versus Elective Caesarean Sections

“…On the other hand, the gastric volume was found to be high for the pregnant women as compared to non-pregnant group (the value for the pregnant women was 0.49 ± 0.4 mL/kg vs. 0.24 mL/kg for non-pregnant women at p<0.05). However, there was no significant difference in the serum gastrin level of the both groups (32.1 ± 12.3 vs. 28.2 ± 8.3 pg/mL) [19].…”

Perioperative fasting and feeding in adults, obstetric, paediatric and bariatric population: Practice Guidelines from the Indian Society of Anaesthesiologists

“…in a randomised control trial including 200 patients compared the residual gastric volume and pH between term pregnant women coming for Caesarean sections and women coming for gynaecological surgeries and found that the mean gastric volume was higher (0.49 ± 0.4 mL/kg vs 0.24 ± 0.2 mL/kg ) and mean gastric content pH was lower (2.4 ± 1.4 vs 3.0 ± 1.9 ) in pregnant women in comparison to non- pregnant women (LOE- Low).

Difficult intubation in pregnancy

“…In late pregnancy, the elevated intra-abdominal pressure, the slower gastric emptying, the decreased tonus of the lower oesophageal sphincter [9] and the presence of nausea increase the probability of vomiting. Concomitantly, the gastric pH is lower than in nonpregnant women [10]. Last but not the least, any problem and risk posed by the airway affects not only the pregnant woman alone but also her unborn baby (or babies), thus having the potential to create a large-scale family tragedy.…”
