Summary of "Gastric Residual Volume after Split-Dose Bowel Preparation versus Conventional Single-Dose Regimen before Anesthetic Colonoscopy."

The aim of this study was to compare gastric residual volume (GRV) in patients given a split-dose versus a conventional single-dose of polyethylene glycol (PEG) preparation before undergoing anesthetic colonoscopy. Methods. In a prospective observational study, we assessed GRV in outpatients undergoing same-day anesthetic gastroscopy and colonoscopy between October 8 and December 30 of 2016. Outpatients were assigned to the split-dose (1 L PEG in the prior evening and 1 L PEG 2-4 h before endoscopy) or single-dose (ingestion of 2 L PEG ≥ 6 h before endoscopy) regimen randomly. Bowel cleansing quality was assessed with the Boston Bowel Preparation Scale (BBPS). Results. The median GRV in the split-dose group (17 ml, with a range of 0-50 ml; N = 65) was significantly lower than that in the single-dose group (22 ml, with a range of 0-62 ml; N = 64; p = 0.005), with a better bowel cleansing quality (BBPS score 8.05 ± 0.82 versus 7.64 ± 1.21; p = 0.028). GRV was not associated with diabetes or the use of medications. Conclusions. GRV after a split-dose preparation and fasting for 2-4 hours is not larger than that after a conventional single-dose preparation and fasting for 6-8 hours. The data indicates that the split-dose bowel preparation might not increase the risk of aspiration.

Medical and Biotech [MESH] Definitions

The volume of air contained in the lungs at the end of a maximal inspiration. It is the equivalent to each of the following sums: VITAL CAPACITY plus RESIDUAL VOLUME; INSPIRATORY CAPACITY plus FUNCTIONAL RESIDUAL CAPACITY; TIDAL VOLUME plus INSPIRATORY RESERVE VOLUME plus functional residual capacity; or tidal volume plus inspiratory reserve volume plus EXPIRATORY RESERVE VOLUME plus residual volume.

The volume of air remaining in the LUNGS at the end of a normal, quiet expiration. It is the sum of the RESIDUAL VOLUME and the EXPIRATORY RESERVE VOLUME. Common abbreviation is FRC.

The volume of air remaining in the LUNGS at the end of a maximal expiration. Common abbreviation is RV.

The dose amount of poisonous or toxic substance or dose of ionizing radiation required to kill 50% of the tested population.

A beta-adrenergic agonist. Nylidrin causes peripheral vasodilation, a positive inotropic effect, and increased gastric volume of gastric juice. It is used in the treatment of peripheral vascular disorders and premature labor.
