RESUMO

BACKGROUND: The efficacy of thoracoscopic intercostal nerve blocks (TINBs) for noxious stimulation from video-assisted thoracic surgery (VATS) remains unclear. The efficacy of TINBs may also be different between nonintubated VATS (NIVATS) and intubated VATS (IVATS). We aim to compare the efficacy of TINBs on analgesia and sedation for NIVATS and IVATs intraoperatively. METHODS: Sixty patients randomized to the NIVATS or IVATS group (30 each) received target-controlled propofol and remifentanil infusions, with bispectral index (BIS) maintained at 40-60, and multilevel (T3-T8) TINBs before surgical manipulations. Intraoperative monitoring data, including pulse oximetry, mean arterial pressure (MAP), heart rate, BIS, density spectral arrays (DSAs), and propofol and remifentanil effect-site concentration (Ce) at different time points. A two way ANOVA with post hoc analysis was applied to analyze the differences and interactions of groups and time points. RESULTS: In both groups, DSA monitoring revealed burst suppression and α dropout immediately after the TINBs. The Ce of the propofol infusion had to be reduced within 5 min post-TINBs in both NIVATS (p < 0.001) and IVATS (p = 0.252) groups. The Ce of remifentanil infusion was significantly reduced after TINBs in both groups (p < 0.001), and was significantly lower in NIVATS (p < 0.001) without group interactions. CONCLUSION: The surgeon-performed intraoperative multilevel TINBs allow reduced anesthetic and analgesic requirement for VATS. With lower requirement of remifentanil infusion, NIVATS presents a significantly higher risk of hypotension after TINBs. DSA is beneficial for providing real-time data that facilitate the preemptive management, especially for NIVATS.

RESUMO

Bronchoscopic interventions (BIs) and airway management for bronchoscopy are exceptionally high-risk procedures not only for anesthesiologists, pulmonologists, but also for nursing staff because they expose nurses to COVID-19-containing droplets. However, perioperative changes can be made to the anesthetic management for nonintubated BIs to minimize the spread of COVID-19.

RESUMO

BACKGROUND: Uniportal video-assisted thoracoscopic surgery (VATS) has recently been introduced for various thoracic diseases. However, management of peripheral lung nodules by uniportal VATS without tracheal intubation has rarely been attempted. We evaluated the feasibility and safety of nonintubated uniportal VATS for peripheral lung nodules. METHODS: From January to March 2014, 32 patients with indeterminate peripheral lung nodules underwent uniportal VATS without tracheal intubation using a combination of intercostal nerve block, intrathoracic vagal block, and target-controlled sedation. Computed tomography-guided dye localization was sometimes used to identify small or ground-glass opacity lesions. RESULTS: A definite diagnosis was obtained in all 32 patients. A wedge resection was performed in 31 patients and a lobectomy in 1. Conversion to nonintubated multiport VATS was required in 4 patients (13%), in 3 because of primary lung cancer requiring further resection for adequacy of margins and in 1 because of difficulty in identifying a small nodule. Conversion to intubated 1-lung ventilation was required in 1 patient (3%) because of vigorous mediastinal movement. Operative complications developed in 2 patients who had air leaks for more than 3 days postoperatively. The median durations of postoperative chest tube drainage and hospital stay were 1 and 3 days, respectively. Postoperative neuralgia that required occasional use of analgesics occurred in only 1 patient (3%), and 97% of patients were very satisfied or satisfied with the resulting scars at 1 month. CONCLUSIONS: Nonintubated uniportal VATS is technically feasible and safe for selected patients and is a less invasive alternative in managing indeterminate peripheral lung nodules.
