Thoracic epidural anesthesia with ipsilateral brachial plexus block is emerging as an alternative to general anesthesia for oncologic breast surgery.1. A 31 year old, pneumonectomised female with a past history of MDR TB was diagnosed with infiltrating ductal carcinoma in left breast 2 months ago and was posted for MRM. She also had moderate Pulmonary Arterial Hypertension. Thoracic epidural anesthesia was induced with 12 ml of 0.5% Ropivacaine at T6-T7 level. Interscalene block was given with 10 ml 0.5% Ropivacaine using peripheral nerve locator. Patient was comfortable throughout the procedure and remained vitally stable. Post-operative analgesia was given with 10 ml of 0.2% ropivacaine and patient was discharged the following week. Thoracic epidural anesthesia provides the advantage of superior intra and post-operative analgesia without the adverse effects of general anesthesia like postoperative nausea, vomiting, respiratory depression and sedation.2 Coupled with interscalene block for axillary lymph node dissection, it can be successfully used as an alternative to GA for MRM.

| Introduction|| |
Pneumonectomized patients and patients with chronic obstructive pulmonary disease are at an increased risk of perioperative complications. Thoracic epidural anesthesia with interscalene block is emerging as an alternative to general anesthesia for oncologic breast surgery. It provides superior postoperative analgesia without respiratory depression and sedation. In our patient, we therefore chose regional over general anesthesia.
| Case Report|| |
A 31-year-old female was diagnosed with Stage III infiltrating intraductal carcinoma of the left breast and was posted for a modified radical mastectomy (MRM). She was on neoadjuvant chemotherapy since 1 month.
She had a history of multidrug-resistant tuberculosis (MDR-TB) 2 years ago, refractory to conservative management, and had undergone left-sided pneumonectomy 6 months ago. In addition, the patient complained of dyspnea, Grade 2 on Modified Medical Research Council Scale. She had no other comorbidities and no relevant family history. On examination, the patient was well preserved and slightly pale. Vital parameters were normal, and on auscultation, breath sounds were absent on the left side.
Patient's hemoglobin was 9 gm%. All other blood and urine investigations were normal. Her chest X-ray showed the absence of left lung [Figure 1]. High-resolution computed tomography thorax showed left side pneumonectomy, mediastinal shift to left, and fibrotic areas in the right lung. Two-dimensional echocardiography showed moderate pulmonary artery hypertension (40 mmHg).
Thoracic epidural was planned as anesthesia of choice, with all preparations for general anesthesia in case of failure. The procedure and anesthetic risks were explained to the patient and relatives, and written consent was obtained.
After confirming overnight fasting, the patient was made to lie supine on the operating table, and standard monitors were attached. Pulse rate was 95 beats/min, oxygen saturation was 98% on room air, electrocardiogram was normal, and baseline blood pressure was 124/80 mmHg.
Patient was premedicated with injection ondansetron 4 mg intravenous (IV) and given sitting position. Under all aseptic precautions, thoracic epidural anesthesia was induced with 18-gauge Tuohy's needle at T6–T7 level using loss of resistance technique [Figure 2]. Catheter was fixed at 8 cm mark, with 4 cm of catheter in epidural space. After giving a test dose with 3 ml 2% injection lignocaine + adrenaline, 12 ml 0.5% injection ropivacaine was injected after negative aspiration. Dense sensory block from level T2 to T8 was achieved within 20 min.
Interscalene block was given on left side, using peripheral nerve locator, with 10 ml 0.5% injection ropivacaine to cover any axillary sparing [Figure 3].
One milligram injection midazolam IV was given after induction and surgery was commenced.
Throughout the surgery, patient's respiratory rate was 14–18 breaths/min, end-tidal carbon dioxide was between 34 and 38, and there was no evidence of diaphragmatic paralysis.
Intraoperatively, 1 L of crystalloids and 1 unit of packed red blood cells were transfused. Three hundred milliliters was total blood loss, and urine output was adequate. The surgery was completed in 2 h.
Patient was comfortable throughout the surgery and vitals remained stable. There was no additional requirement for sedative or analgesic agents.
After monitoring the patient for 1 h in the recovery room, patient was shifted to the ward in a stable condition. Postoperative analgesia was given through epidural catheter, with 10 ml 0.2% ropivacaine 8 h after surgery and 12 hourly thereafter for 36 h, following which, the epidural catheter was removed. The patient was discharged the following week.
| Discussion|| |
With the advent of improvement in surgical technique, after year 2014, more and more MDR-TB patients were treated with combined medical and surgical therapy to achieve better morbidity and mortality profile.
Pneumonectomized patients posted for surgery pose a wide range of perioperative complications. Excessive mediastinal shift away from the pneumonectomy space into the contralateral hemithorax can result in decreased lung volume, retained secretions, and respiratory compromise.
General anesthesia and invasive mechanical ventilation can cause barotrauma and precipitate pulmonary edema and acute respiratory distress syndrome in patients with pulmonary arterial hypertension.
Breast cancer is the most common female cancer worldwide representing nearly a quarter (23%) of all cancers in women. For infiltrating ductal carcinoma stage IIb or more, MRM with neoadjuvant chemotherapy continues to be the mainstay of treatment. In most centers in India, oncologic breast surgeries are performed under general anesthesia. However, we are slowly observing a shift toward regional and locoregional anesthesia for these surgeries.
Sundarathiti et al. conducted a clinical trial in 2005 on fifty females with breast cancer posted for MRM. Half the patients were operated under general anesthesia and half under thoracic epidural and interscalene block with 0.2% injection ropivacaine. They concluded that thoracic epidural anesthesia is one of the regional anesthetic techniques that can be performed using a low dose of local anesthetic in combination with ipsilateral brachial plexus block for axillary node dissection. Thoracic epidural can provide better pain relief without potential paralysis of respiratory muscle and sedation that are associated with general anesthesia.
Doss et al., in their study, continuous thoracic epidural anesthesia with 0.2% ropivacaine versus general anesthesia for perioperative management of MRM concluded that thoracic epidural with ropivacaine provides better postoperative pain relief and less nausea and vomiting, facilitates postanesthesia recovery, and gives greater patient satisfaction than general anesthesia.
Local anesthetic infiltration has also been used along with thoracic epidural anesthesia for MRM for axillary lymph node dissection. Wound infiltration of local anesthetic agents may be used for postoperative analgesia.
Kaya et al., in their study on postoperative analgesia after MRM, demonstrated that the use of interscalene block in patients undergoing MRM improved pain scores and reduced morphine consumption during the first 24 h postoperatively.
Paravertebral block is another method that can be employed as an alternative to general anesthesia for mastectomies. Surgical anesthesia by thoracic paravertebral block alone, however, causes considerable patient's discomfort during neural block and surgery. Ono et al. concluded that the combined use of paravertebral block and general anesthesia can be a preferable choice of anesthesia for patients undergoing major breast cancer surgery.
| Conclusion|| |
Successful intra and postoperative anesthetic management of pneumonectomized patient for MRM was achieved using thoracic epidural anesthesia with interscalene block.
Patient satisfaction was good and postoperative period was without adverse effects of general anesthesia such as respiratory depression and pulmonary edema, which may be deleterious in such patients.
Thoracic epidural anesthesia can serve as an alternative to general anesthesia for MRM and other breast surgeries.
