The effect of transcutaneous electric nerve stimulation on chronic postoperative pain and long-term quality of life

BACKGROUND

This study aims to investigate the effects of transcutaneous electrical nerve stimulation on early-stage postoperative pain and long-term quality of life in patients undergoing thoracotomy.

METHODS

Between January 2019 and September 2019, a total of 100 patients (76 males, 24 females; mean age: 57.9±11.9 years; range, 51 to 79 years) who underwent thoracotomy due to benign or malignant lesions were included. The patients were divided into two groups: 50 patients who received transcutaneous electrical nerve stimulation (Group 1) and a control group of 50 patients who did not receive transcutaneous electrical nerve stimulation (Group 2). The Short Form-36 life quality scale was used to evaluate patients' quality of life at one month before and after surgery.

RESULTS

The mean length of hospital stay was 4.9±3.1 days in Group 1 and 6.2±4.6 days in Group 2 (p=0.008). There were no statistically significant differences in early-stage postoperative pain scores between the groups (p>0.05). Compared to Group 2, Group 1 had significantly lower pain scores and higher life quality scores pre- and postoperatively (p<0.05).

CONCLUSION

Transcutaneous electrical nerve stimulation is an effective method to manage chronic pain in the postoperative period. On the other hand, it does not effectively reduce early-stage postoperative pain or affect complication rates. The prevention of chronic postoperative pain by transcutaneous electrical nerve stimulation improves long-term quality of life of patients.

Effect of intraoperative blood loss on postoperative pulmonary complications in patients undergoing video-assisted thoracoscopic surgery

Background

We aimed to investigate the impact of intraoperative blood loss on postoperative pulmonary complications in patients who underwent video-assisted thoracoscopic lobectomy for nonsmall cell lung cancer.

Methods

Data of a total of 409 patients (227 males, 182 females; median age: 62 years; range, 20 to 86 years) who underwent lung resection for Stage I-IIIa non-small cell lung cancer in our clinic between July 2017 and April 2018 were retrospectively analyzed. The receiver operating characteristic analysis was used to confirm the threshold value of intraoperative blood loss for the prediction of postoperative pulmonary complications. Propensity score matching was performed to compare between high-intraoperative blood loss and low-intraoperative blood loss groups. A post-matching conditional logistic regression was conducted to determine the independent risk factors for postoperative pulmonary complications.

Results

Of the patients, 86 (21.03%) developed postoperative pulmonary complications. In the propensity score matching analysis, intraoperative blood loss was shown to be a predictive factor of postoperative pulmonary complications (3.992; 95% confidence interval [CI]: 1.54-10.35; p=0.004). The rate of postoperative pulmonary complications in high-intraoperative blood loss group was significantly higher than that the low-intraoperative blood loss group (37.5% vs. 13.9%, respectively; p=0.003). The postoperative length of stay and duration of postoperative antibiotic use were significantly prolonged in the high-intraoperative blood loss group.

Conclusion

Intraoperative blood loss serves as a significant risk factor for postoperative pulmonary complications after lung resection for non-small cell lung cancer. Surgeons should strive to reduce intraoperative blood loss for better surgical outcomes.

Comparison of short-term quality of life in patients undergoing video-assisted thoracoscopic surgery versus thoracotomy

Background

This study aims to compare the short-term quality of life of patients undergoing video-assisted thoracoscopic surgery versus thoracotomy.

Methods

A total of 96 patients (58 males, 38 females; mean age 58.4±11.7 years; range, 18 to 80 years) who underwent video-assisted thoracoscopic surgery or thoracotomy in our hospital between March 2018 and March 2019 were retrospectively analyzed. Demographic and clinical characteristics and comorbidities of the patients were recorded. Quality of life of the patients was evaluated using the Short Form-36 health survey at the first postoperative month.

Results

Of the patients, 43 (44.8%) were treated by video-assisted thoracoscopic surgery and 53 (55.2%) by thoracotomy. Complications occurred in nine (20.9%) patients following video-assisted thoracoscopic surgery and in 12 (22.6%) patients following thoracotomy (p=0.840). At one month postoperatively, the patients in the video-assisted thoracoscopic surgery group had a better quality of life than those in the thoracotomy group (p<0.05).

Conclusion

Our study results suggest that both recovery and short-term quality of life seem to be better in patients undergoing video-assisted thoracoscopic surgery than in those treated by thoracotomy.
