Pain amelioration after thoracotomy: a prospective, randomized study.

A G de la Rocha, K Chambers

    The Annals of Thoracic Surgery
    |March 1, 1984
    PubMed
    Summary

    Continuous intercostal nerve blocks significantly improve breathing post-surgery. Anterolateral thoracotomy also offers better pain relief and lung function compared to posterolateral approaches.

    Area of Science:

    • Thoracic Surgery
    • Pain Management
    • Pulmonary Function Testing

    Background:

    • Posterolateral thoracotomy often leads to significant postoperative pain, impacting respiratory mechanics.
    • Effective pain management is crucial for optimizing recovery after thoracic surgery.

    Purpose of the Study:

    • To compare the efficacy of different pain control methods following posterolateral thoracotomy.
    • To evaluate the impact of anterolateral thoracotomy on postoperative pain and breathing performance.

    Main Methods:

    • Twenty patients were divided into four groups: control, intercostal nerve block at closure, continuous intercostal nerve block for five days, and electronic pain control.
    • A fifth group underwent anterolateral thoracotomy and was compared to the control group.
    • Bedside spirometry was used daily for five days to assess breathing performance.

    Main Results:

    • Continuous intercostal nerve block (Group 3) and anterolateral thoracotomy (Group 5) showed significantly better forced expiratory volume in one second (FEV1) compared to the control group (Group 1) five days postoperatively.
    • FEV1 was 52.4% (±9.2%) in Group 3 and 52.0% (±7.5%) in Group 5, versus 38.4% (±8.8%) in Group 1 (p < 0.05).
    • Bedside spirometry proved a reliable method for assessing postoperative ventilatory changes due to pain.

    Conclusions:

    • Continuous intercostal nerve blocks substantially decrease pain after posterolateral thoracotomy.
    • Anterolateral thoracotomy is less painful than posterolateral thoracotomy and is recommended for patients with reduced pulmonary reserve.
    • Bedside spirometry is a simple and effective tool for evaluating postoperative pain's impact on breathing.
