Application of intraoperative modified position in lung cancer patients undergoing thoracoscopic radical resection
Objective To analyze the application effect of intraoperative modified position in lung cancer patients un-dergoing thoracoscopic radical resection.Method A total of 108 lung cancer patients who underwent thoracoscopic radi-cal resection were divided into the conventional group(54 cases)and the improved group(54 cases)according to differ-ent positions during operation.In the conventional group,the conventional position was adopted,and in the improved group,the modified position was adopted.Surgical indicators,circulation indicators[systolic blood pressure(SBP),dia-stolic blood pressure(DBP),mean arterial pressure(MAP),intraocular pressure],respiratory indicators[peak airway pres-sure(Ppeak),pulse blood oxygen saturation(SpO2),partial pressure of end-tidal carbon dioxide(PetCO2),airway pressure],blood flow velocity of both lower limbs and postoperative complications were compared between the two groups.Result The patients in the improved group had significantly longer posture time,significantly shorter operation time,significant-ly less intraoperative blood loss,and significantly higher satisfaction score than the conventional group,the differences were statistically significant(P<0.01).During the operation,SBP,DBP,MAP and intraocular pressure in conventional group were higher than those before postural placement and improved group,and the differences were statistically signifi-cant(P<0.05).During the operation,PetCO2,Ppeak,and SpO2 of the improved group were higher and airway pressure was lower than those before postural placement,PetCO2,Ppeak,SpO2 and airway pressure of the conventional group were high-er than those before postural placement,PetCO2,Ppeak and airway pressure of the improved group were lower than those of the conventional group,and SpO2 was higher than that of the conventional group,the differences were statistically signifi-cant(P<0.05).During the operation,the blood flow velocity of both lower limbs in both groups were lower than those be-fore postural placement,and the blood flow velocity of both lower limbs in the improved group were higher than those in the conventional group,the differences were statistically significant(P<0.05).The total incidence of postoperative compli-cations in the improved group was lower than that in the conventional group,and the difference was statistically signifi-cant(P<0.05).Conclusion The intraoperative modified position is more meet the individual requirements of patients un-dergoing thoracoscopic radical resection,can shorten the operation time,reduce the amount of intraoperative blood loss,reduce the impact on the circulatory and respiratory indexes of patients by alleviating the compression of the chest cavity,reduce the degree of venous blood flow of patients'lower limbs,and reduce the risk of postoperative complications.
