Abstract: Objective：To statistically analyze the preventive appliction of antibiotics during the perioperative period of class Ⅱ incision surgery in a hospital from 2018 to 2020， so as to strengthen the attention of clinicians on the rational preventive use of antibiotics during the perioperative period of class Ⅱ incision surgery.Methods：The types of selected antibiotics， timing and duration of drug administration were used as the key evaluation factors， and 731 cases of perioperative prophylactic use of antibiotics in class Ⅱ incision surgery in a hospital from 2018 to 2020 were randomly selected for comment. Results： Antibacterial drugs were preventively used in all the 731 cases of type Ⅱ incision surgery. The antibacterial drugs selected were mostly cephamycins， cephalosporin antibiotics+nitroimidazoles， and two-drug combination therapy was mainly used in gynecological operations such as hysterectomy， fallopian tube excision and hysteromyomectomy.The timing of medication met the requirements except that the time of drug administration was more than 60 min before otolaryngology surgery.The perioperative medication courses of gynecological hysterectomy， otolaryngology tonsillectomy， surgical laparoscopic gallbladder resection were relatively long， which were 3~7 d. Conclusion： There were some irrational use problems such as selection of broad-spectrum antibiotics， improper timing of medication， and long treatment course of antibiotics in the perioperative period of class Ⅱ incision surgery in the hospital. Medical institutions should pay more attention to the rationality of prophylactic use of antibiotics in class Ⅱ incision surgery.
