Systemic and alveolar inflammatory response in the dependent and nondependent lung in patients undergoing lung resection surgery

Analysis of middle- and long-term efficacy of thoracoscope-assisted segmental resection of the lung on non-small cell lung cancer in the early stage

We investigated the short- and long-term efficacy of thoracoscope-assisted segmental resection of lung of non-small cell lung cancer (NSCLC). We selected a total of 94 patients with lung cancer in the early stage who were admitted to The First People's Hospital of Xuzhou for treatment between March 2011 and February 2012. Patients were divided randomly into either the control group (n=47) or the observation group (n=47). In the observation group, patients received thoracoscope-assisted segmental resection of lung, while in the control group, the conventional thoracic surgery was performed for treatment. After surgeries, we observed the incidence rate of complications among the two groups, and enzyme-linked immunosorbent assay (ELISA) was adopted to detect levels of inflammatory factors. We also compared the cardiac and pulmonary functions, the levels of immunoglobulins and subgroups of T lymphocytes in the peripheral blood of the patients. In addition, all patients attended a 5-year follow-up to determine the recurrence and survival rate. Compared to the control group, patients in the observation group had significantly less intra-operative bleeding volume, a shorter duration of surgery, and suffered slighter pain after surgery (P<0.05). After surgery, the incidence rate of complications in the observation group was significantly lower than that in the control group (P<0.05). After surgeries, patients in both groups experienced a remarkable improvement in cardiac and pulmonary functions, and the improvement in the observation group was superior to that of the control group (P<0.05). During the 5-year follow-up, the survival rate of the observation group is significantly higher than that in thecontrol group, and patients in the observation group experienced a lower recurrence rate than those in the control group (P<0.05). Thus, thoracoscope-assisted segmental resection of lung is of great significance in clinical practice.

Nalbuphine analgesic and anti-inflammatory effects on patients undergoing thoracoscopic lobectomy during the perioperative period

This study sought to investigate the analgesic effects of nalbuphine on patients undergoing thoracoscopic lobectomy during the perioperative period, as well as its effects on inflammatory cytokines. We selected 92 patients with early lung cancer who were admitted to Xiangyang No. 1 People's Hospital between January 2016 and December 2016. The patients were randomly divided into control and observation groups (n=46 each). All patients underwent thoracoscopic lobectomy, with those in the observation group receiving intravenous nalbuphine hydrochloride prior to induction (the control group received saline). Intraoperative blood loss, operation time and anesthetic dosages were compared between groups. The analgesic effects during the perioperative period were compared using a visual analogue scale. The adverse effects of anesthetics (nausea, vomiting, dizziness and drowsiness) were compared between the two groups. Finally, serum inflammatory cytokine [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and IL-10] levels were measured using ELISA at 1, 3, 5 and 7 days after operation. There were no significant differences in intraoperative blood loss and operation time between the two groups (p>0.05). However, dosages of propofol and remifentanil used were lower in the observation group than in the control group (p<0.05), and the effective rate of postoperative analgesia in the observation group was significantly higher than that in the control group (p<0.05). The degree of postoperative pain in both groups were lower than preoperative rates (p<0.05), while the incidence of adverse reactions in the observation group was significantly lower than in the control group (p<0.05). Finally, TNF-α, IL-6 and IL-10 levels were significantly lower in the observation group relative to the control group at 1, 3, 5 and 7 days after operation (p<0.05). Therefore, nalbuphine has a significant analgesic effect during thoracoscopic lobectomy. The application of nalbuphine can reduce the incidence of adverse reactions, reduce postoperative inflammatory responses, and promote rapid patient recovery, thus demonstrating the clinical value of nalbuphine.
