Study on the Application Effect of Feedforward Control Combined with Family Awakening in Elderly Patients Undergoing Radical Lung Cancer Surgery during Anesthesia Recovery

Abstract

Objective : To investigate the application effect of feedforward control combined with family awakening in elderly patients undergoing radical lung cancer surgery during the post-anesthesia care unit (PACU) recovery period, providing evidence-based support for reducing complications such as emergence agitation, hypothermia, hypoxemia, pain, and delirium, and improving recovery safety and humanistic nursing quality. Methods : A total of 340 elderly patients undergoing thoracoscopic radical lung cancer surgery from July to December 2024 were randomly divided into a control group (170 cases, conventional recovery nursing) and an intervention group (170 cases, feedforward control + family awakening). The intervention group implemented integrated measures, including preoperative risk assessment, perioperative stratified temperature management, airway safety management, multimodal analgesia, standardized family awakening, circulatory stability control, and delirium prevention. The incidence of agitation, Riker Sedation-Agitation Scale (SAS) scores, body temperature, pain scores (NRS, FLACC), hypoxemia, recovery time, and complication rates were compared between the two groups. Results : The incidence of agitation in the intervention group (7.65%) was significantly lower than that in the control group (22.94%). SAS scores, FLACC pain scores, and NRS scores were significantly lower in the intervention group (P < 0.05). The incidence of hypothermia, hypoxemia, nausea and vomiting, delirium, and pulmonary complications was significantly lower in the intervention group (P < 0.05). The recovery time of spontaneous breathing, eye-opening time, extubation time, and PACU stay time were significantly shorter in the intervention group (P < 0.05). Body temperature, blood oxygen saturation, heart rate, and blood pressure were more stable at all time points. Conclusion : Feedforward control combined with family awakening can significantly reduce complications during anesthesia recovery in elderly patients undergoing radical lung cancer surgery, alleviate agitation and pain, shorten recovery time, and enhance recovery safety and comfort. This approach aligns with the Enhanced Recovery After Surgery (ERAS) and humanistic nursing concepts and is worthy of promotion in thoracic surgery anesthesia recovery nursing.
