Perioperative Gastric Emptying Is Not a Predictor of Early Postoperative Nausea and Vomiting in Patients Undergoing Laparoscopic Cholecystectomy

Randomized clinical trial of the effects of oral preoperative carbohydrates on postoperative nausea and vomiting after laparoscopic cholecystectomy

“…A VAS has been used previously for the assessment of postoperative nausea in laparoscopic cholecystectomy19, 20. In the present study, such scoring was combined with an objective registration of PONV episodes in an effort to increase the accuracy of the evaluation.…”

“…In addition, the patients rated their sense of nausea using a 100‐mm visual analogue scale (VAS)7, 14, 19, 20, at the preadmission visit 1 week before surgery and on the day after surgery, that is at about 24 h after operation which was the planned time of hospital discharge. VAS scores for overall pain were obtained in parallel17, 21.…”

Liraglutide: short‐lived effect on gastric emptying—long lasting effects on body weight

“…It is tempting to speculate that a continued marked effect on GE as seen with exenatide is causing nausea in some patients. However, at present there exist no conclusive evidence for a direct and causative link between inhibition of GE and nausea [39,40]. In this study, we used paracetamol uptake as a measure of GE.…”

Validation of the paracetamol absorption test for measuring gastric tube emptying in esophagectomized patients versus gold standard scintigraphy

“…Consequently, the plasma concentration of paracetamol over time reflects GER. In non-operated patients, the paracetamol absorption test has been validated by comparison with scintigraphy and has been used for measuring GER [13][14][15][16][17][18][19][20]. However, it is not known if this test can be used to evaluate gastric tube emptying in esophagectomized patients.…”
