Double edge closure: a novel technique for reducing post-thoracotomy pain. A randomized control study

The efficacy of pregabalin for pain control after thoracic surgery: a meta-analysis

BACKGROUND

Pregabalin may have some potential in alleviating pain after thoracic surgery, and this meta-analysis aims to explore the impact of pregabalin on pain intensity for patients undergoing thoracic surgery.

METHODS

PubMed, EMbase, Web of science, EBSCO and Cochrane library databases were systematically searched, and we included randomized controlled trials (RCTs) assessing the effect of pregabalin on pain intensity after thoracic surgery.

RESULTS

Five RCTs were finally included in the meta-analysis. Overall, compared with control intervention for thoracic surgery, pregabalin was associated with significantly reduced pain scores at 0 h (mean difference [MD]=-0.70; 95% confidence interval [CI]=-1.10 to -0.30; P = 0.0005), pain scores at 24 h (MD=-0.47; 95% CI=-0.75 to -0.18; P = 0.001) and neuropathic pain (odd ratio [OR] = 0.24; 95% CI = 0.12 to 0.47; P < 0.0001), but demonstrated no obvious impact on the incidence of dizziness (OR = 1.07; 95% CI = 0.15 to 7.46; P = 0.95), headache (OR = 1.00; 95% CI = 0.30 to 3.35; P = 1.00) or nausea (OR = 1.24; 95% CI = 0.46 to 3.35; P = 0.68).

CONCLUSIONS

Pregabalin may be effective to alleviate the pain after thoracic surgery.

Role of Perioperative Pregabalin in the Management of Acute and Chronic Post-Thoracotomy Pain

BACKGROUND:

Post-thoracotomy pain syndrome (PTPS) can be challenging to treat.

AIM:

This study aimed to evaluate the efficacy of perioperative pregabalin in the prevention of acute and chronic post-thoracotomy pain.

METHODS:

Sixty patients scheduled for thoracotomy for oncologic surgeries were randomly allocated to one of two groups; Pregabalin and Control. In the Pregabalin group, pregabalin 150 mg was administered one hour before thoracotomy and 12 hours later, then every 12 hours for five days. Pain intensity was assessed using the Visual Analogue Scale (VAS) at rest (VAS-R) and dynamic (VAS-D) in the ICU and during the next four days. Morphine consumption and the frequency of side effects were recorded. Assessment of PTPS was done using the Leeds Assessment of Neuropathic Symptoms and Signs (LANSS) scale at 1, 2, and 3 months.

RESULTS:

The VAS-R and VAS-D scores and the total morphine consumption were significantly lower in Pregabalin group during days 0 through 4. Neuropathic pain, allodynia, and hyperalgesia were significantly lower in Pregabalin group after 1, 2, and 3 months.

CONCLUSION:

Pregabalin is effective in the reduction of chronic neuropathic pain at 1, 2, and 3 months after thoracotomy and it also reduces pain and opioid consumption during the acute postoperative period with few adverse effects.

If post-thoracotomy pain is the target, Integrated Thoracotomy is the choice

OBJECTIVES

Despite the overgrowth of procedures done by VATS, there are still needs for thoracotomy. Post-thoracotomy pain plays an important role in many post-operative morbidities. Surgeons should make efforts to evolve new techniques to reduce post-thoracotomy pain with its associated morbidities. This trial aimed to study the impact of combining lack of rib retraction with protection of both intercostal nerves on post-operative pain.

METHODS

This was a prospective study of 57 patients who had Integrated thoracotomy (I group) which consists of modified French window with Double-Edge closure. The results of I group were compared to our previous study that contained two groups 60 patients each, double edge (DE group) in which standard thoracotomy was closed using double-edge technique and (PC group) in which pericostal sutures was used for closure of thoracotomy. Outcomes assessed were operative time, time to ambulation, doses of analgesics injected in the epidural catheter, post-operative complications, chest tube drainage, hospital stay, and pain score and use of analgesics during the first post-operative year.

RESULTS

All groups had similar demographics, operative time, and incisions length, but in I group, there were significantly a smaller number of lobectomies and pneumonectomies. Patients in I group had significantly lower time to ambulation, epidural doses and post-operative pain score throughout the first week. Patients in the (I group) had a significantly lower pain score throughout the first 9 months post-operatively. Up to 6 months post-operatively, there was significantly less use of analgesics among the I group.

CONCLUSION

The combination of retractor-free exposures and neurovascular exclusion sutures for thoracotomy is safe and effective in decreasing post-thoracotomy pain and use of analgesics.
