Anesthetic effect of ultrasound-guided multiple-nerve blockade in modified radical mastectomy in patients with breast cancer

INTRODUCTION: Routine anesthesia modality for modified radical mastectomy (MRM) includes general anesthesia (GA), epidural blockade-combined GA and nerve blockade-combined GA. However, GA has been associated with postoperative adverse effects such as vertigo, postoperative nausea and vomiting and re...

Sumario:INTRODUCTION: Routine anesthesia modality for modified radical mastectomy (MRM) includes general anesthesia (GA), epidural blockade-combined GA and nerve blockade-combined GA. However, GA has been associated with postoperative adverse effects such as vertigo, postoperative nausea and vomiting and requirement for postoperative analgesia, which hinders recovery and prognosis. Moreover, combined blockade of thoracic paravertebral nerves or intercostal nerves and adjuvant basic sedation for massive lumpectomy provided perfect anesthesia and reduced opioid consumption, whereas the excision coverage did not attain the target of MRM. Regional anesthesia strategies involving supplementation of analgesics in ultrasound-guided multiple nerve blocks have garnered interests of clinicians. Nevertheless, the precise effects of intercostal nerves, brachial plexus and supraclavicular nerves in MRM in patients with breast cancer remain obscure. METHODS: Eighty female patients with breast cancer scheduled for MRM were recruited in the present trial between May, 2019 and Dec., 2019 in our hospital. The patients ranged from 30 to 65 years of age and 18∼30 kg/m(2) in body-mass index, with the American Society of Anesthesiologists I or II. The patients were randomized to ultrasound-guided multiple nerve blocks group and GA group. The patients in multiple nerve blocks group underwent ultrasound guided multiple intercostal nerve blocks, interscalene brachial plexus and supraclavicular nerve blocks, (local anesthesia with 0.3% ropivacaine: 5 ml for each intercostal nerve block, 8 ml for brachial plexus block, 7 mL for supraclavicular nerve block) and basic sedation and intraoperative mask oxygen inhalation. The variations of hemodynamic parameters such as mean arterial pressure, heart rate (HR) and pulse oxygen saturation were monitored. The visual analog scale scores were recorded at postoperative 0 hour, 3 hour, 6 hour, 12 hour and 24 hour in resting state. The postoperative adverse effects, including vertigo, postoperative nausea, and vomiting, pruritus, and urinary retention and so on, as well as the analgesic consumption were recorded. CONCLUSIONS: The ultrasound guided multiple intercostal nerve blocks, brachial plexus and supraclavicular nerve blocks could provide favorable anesthesia and analgesia, with noninferiority to GA and the reduced incidence of adverse effects and consumption of postoperative analgesics.
