BackgroundPatient comfort is an important part of laceration repair.MethodsThe study was a randomized single-blind cross-over trial in which each participant received 250 ml warmed and 250 ml room temperature saline irrigation in simple linear wounds after a local anesthetic was instilled. The solutions and the order of irrigation (warmed first versus second) were separately randomized with a washout period between. Investigators obtaining scores were blinded. Participants determined preferred solution, whether the solution was soothing, and which caused the most discomfort. Participants rated the pain of irrigation using separate Visual Analog Scale scores.ResultsThirty-eight patients were enrolled in the study. Significantly more preferred warmed to room temperature solutions (difference, 34%; 95% confidence interval, 5.7-63). A Wilcoxon signed-rank test for paired data showed no order effect (P = 0.49) or difference in pain measured according to the Visual Analog Scale (P = 0.082).ConclusionWarmed saline was more comfortable and soothing than room temperature saline as a wound irrigant among patients with linear lacerations.
