Postoperative nausea and vomiting in scoliosis children and its influencing factors

Abstract

Objective To investigate the postoperative nausea and vomiting (PONV) in scoliosis children and to explore its influencing factors so as to provide a basis for clinical nursing intervention. Methods From June 2017 to December 2018, we selected 417 scoliosis children with orthopedic surgery in Orthopedics Department at Chinese Academy of Medical Sciences & Peking Union Medical College Hospital by convenience sampling. The incidence of PONV, general information, disease data and surgery were collected and Logistic regression was used to analyze the influencing factors of PONV in children undergoing scoliosis orthopedic surgery. Results There were 282 (67.63%) children with PONV within 24 hours after surgery including 221 cases in the early stage and 61 in the late stage. Simple correlation showed that there were statistical differences in the incidence of PONV within 24 hours among children with different ages, types of scoliosis, history of PONV or motion sickness of children, improvement rate of scoliosis correction, using of patient-controlled analgesia, fasting time before surgery, surgery time and hemoglobin of children (P<0.05) . Logistic regression showed that the influencing factors of PONV of children included surgery time, ages, improvement rate of scoliosis correction, hemoglobin, fasting time, history of PONV or motion sickness with statistical differences (P<0.05) . Conclusions Children after scoliosis correction have the high incidence rate of PONV. Nurses should fully assess the risk of PONV in children with the scientific evaluation methods to reduce the fasting time before surgery of children. Nurses should pay more attention to children with high risk of PONV and take measures to reduce and avoid the occurrence of PONV.
