    BackgroundsTo observe the effect of using mild intraoperative hyperventilation on the incidence of postlaparoscopic shoulder pain (PLSP) in patients undergoing laparoscopic sleeve gastrectomy.MethodsEighty patients undergoing laparoscopic sleeve gastrectomy, aged 22 to 36 years, with American Society of Anesthesiologists grade I or II, were divided into 2 groups according to method of random number table. A mild hyperventilation was used in group A with controlling pressure of end-tidal carbon dioxide (PETCO2) of 30 to 33 mm Hg, while conventional ventilation was used in group B with PETCO2 35 to 40 mm Hg during the operation. The incidence and severity of PLSP, dosage of remedial analgesia and adverse reactions such as nausea and vomiting at 12, 24, 48, 72 hours and 1 week after surgery were recorded. Arterial blood gas was recorded before anesthesia induction, 20 minutes after pneumoperitoneum, during suture skin, and 24 hours after surgery.ResultsCompared with 12, 24, 48, and 72 hours after operation, the incidence of PLSP at 1 week decreased significantly (P < .01). Compared with group B, the incidence of PLSP, pain score, and dosage of remedial analgesic at 12, 24,48, 72 hours, and 1 week after surgery were significantly decreased (P < .01). There was no significant difference between the 2 groups in arterial blood gas analysis before anesthesia induction, 20 minutes after pneumoperitoneum, during suture skin, and 24 hours after surgery (P > .05). There were no significant difference of the occurrence of adverse reactions such as nausea and vomiting between the 2 groups within 1 week after surgery (P > .05).ConclusionMild hyperventilation can reduce the incidence and severity of PLSP after laparoscopic sleeve gastrectomy without increasing the associated adverse effects.Copyright © 2023 the Author(s).
