Objective To research the relationship between decrease of serum surfactant protein D (SP-D) level reduced by pulmonary rehabilitation training and postoperative pulmonary complications (PPC). Methods From May 2015 through December 2015, 80 consecutive non-small cell lung cancer (NSCLC) patients with surgical treatment in West China Hospital, who were at least with a high risk factor, were randomly divided into two groups including a group R and a group C. There were 36 patients with 25 males and 11 females at age of 63.98±8.32 years in the group R and 44 patients with 32 males and 12 females at age of 64.58±6.71 years in the group C.The group R underwent an intensive preoperative pulmonary rehabilitation (PR) training for one week, and then with lobectomy. The group C underwent only lobectomy with conventional perioperative managements. Postoperative pulmonary complications, average days in hospital, other clinic data and the serum SP-D level in a series of time from the date of admission to discharge (5 time points) were analyzed. Results The incidence of PPC in the group R was 5.56%(2/36),which was lower than that in the group C (P=0.032). The descender of the serum SP-D level of the patients in the group R (30.75±5.57 ng/mlvs. 24.22±3.08 ng/ml) was more obvious than that in the group C (31.16±7.81 ng/mlvs. 30.29±5.80 ng/ml,P=0.012). The descender of the serum SP-D level of the patients with PPC was more obvious than that of patients without PPC (P=0.012). Conclusion The preoperative PR training could reduce the PPC of lung cancer surgery with high risk factors. The serum SP-D level could reflect the effect of preoperative pulmonary rehabilitation training.
ObjectiveTo clarify the effectiveness of preoperative pulmonary rehabilitation (PPR) and provide evidence for the application of PPR on lung cancer patients by meta-analysis.MethodsAccording to inclusion and exclusion criteria, literatures related to PPR on lung cancer patients were retrieved from major databases between the date of establishment of each database and January 2019, and then data required were extracted from the selected literatures. Meta-analysis was conducted by RevMan 5.0.ResultsTwelve randomized controlled trials were involved in meta-analysis, including 658 patients who were well-diagnosed and prepared for surgery, with 307 patients in the PPR group and 351 patients in the control group. The results of the meta-analysis showed that in the PPR group, the pulmonary function including forced vital capacity [MD=0.31, 95%CI (0.21, 0.42), P<0.01], forced expiratory volume in one second [MD=0.27, 95%CI (0.20, 0.34), P<0.01] and activity tolerance including 6-minute walk distance [MD=50.55, 95%CI (35.98, 65.13), P<0.01] were significantly better than the control group, and the postoperative complication rate was lower ［MD=0.28, 95%CI (0.18, 0.43), P<0.01］, postoperative hospital stay was shorter [MD=–2.09, 95%CI (–2.41, –1.77), P<0.01].ConclusionsA period of PPR on lung cancer patients can improve postoperative pulmonary function and activity tolerance, and reduce postoperative complications and hospital stay, which is beneficial to postoperative recovery.
