Correspondence The chewing gum controversy—time for a consensus? We read with interest the meta-analysis by Ouanes et al [1] reviewing the role of perioperative chewing gum on gastric fluid volume and gastric pH. It is reassuring to find that although chewing gum preoperatively may cause small increases in gastric fluid volumes (MD = 0.21 mL/kg, P = .03) with no change in gastric pH, that this is most likely to carry no significant risk of clinical aspiration. Despite these conclusions, it is disappointing that currently, there is a vast difference in clinical practice for managing those patients who have chewed gum ranging from proceeding without delay [2], waiting 2 hours [3] or assuming that chewing gum is a solid foodstuff and waiting 6 hours [4]. One solution to improving patient satisfaction, clinician consistency, and theater utilization would be the publication of a consensus working party statement regarding the chewing of gum, tobacco, and the sucking of boiled sweets. This would be similar to the landmark American Society of Anesthesiologists' article on shortened fasting times [5] and would ensure that patients are given the correct information before admission to hospital for elective surgery.
