RESUMO
Tracheal bronchus is a rare congenital tracheal abnormality that generally refers to the right upper lobe bronchus of the lung that originates from the trachea. Tracheal bronchus is usually asymptomatic and is often accidentally detected by fiberoptic bronchoscopy or computed tomography for other conditions. Depending on the location of the tracheal bronchial opening and possible anatomical variations, the management of 1-lung ventilation in patients with tracheal bronchus is a significant challenge for anesthesiologists. To provide a reference for anesthesiologists to better manage anesthesia in such patients, we review the pathophysiology, definition, and Conacher classification of tracheal bronchus and then discuss the diagnosis of tracheal bronchus and management of 1-lung ventilation during anesthesia according to the Conacher classification.
RESUMO
OBJECTIVE: To investigate the effects of pregabalin combined with tramadol/paracetamol on acute pain in patients with CT-guided puncture localization of pulmonary nodules. MATERIALS AND METHODS: In this randomized, placebo-controlled and single-center study, 120 patients were allocated randomly to four groups: the control group (Group P), the pregabalin-placebo group (Group BP), the tramadol/paracetamol-placebo group (Group AP), and the pregabalin-tramadol/paracetamol group (Group AB). The primary outcome was the NRS (Numerical Rating Scale) score. Other outcomes included systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), pulse oxygen saturation (SpO2), the incidence of moderate to severe pain, the analgesia recovery ratio, the incidence of adverse drug reactions and patients' satisfaction. RESULTS: No significant interaction was detected between the interventions (P = 0.752). The NRS score of the Taking pregabalin group and the Taking tramadol/paracetamol group were significantly lower than those of the Not-taking pregabalin group and the Not-taking tramadol/paracetamol group respectively (P < 0.05). There was significant difference in the NRS scores among the four groups (P < 0.001). The NRS score of Group AB was significantly lower than that of Group P (P < 0.001), Group BP (P < 0.001) and Group AP (P = 0.001). At the same time, the NRS scores of Group BP (P < 0.001) and Group AP (P < 0.001) were significantly lower than those of Group P, but there was no significant difference between Group BP and Group AP (P = 1.000). The SBP, DBP, HR, the incidence of moderate to severe pain and the analgesia recovery ratio of Group AB were significantly lower than those of Group P (P < 0.05), while the SpO2 and the number of people who were very satisfied were significantly higher than those of Group P (P < 0.05). There was no significant difference in the incidence of adverse drug reactions among the four groups (P = 0.272). CONCLUSIONS: The combination or single use of pregabalin and tramadol/paracetamol can effectively relieve the acute pain after localization. Pregabalin combined with tramadol/paracetamol has the best analgesic effect and significantly reduces the hemodynamic fluctuations, with high safety and low incidence of adverse drug reactions, which has a certain clinical popularization and application value.

BACKGROUND: Opioids are the main analgesic drugs used in the perioperative period, but they often have various adverse effects. Recent studies have shown that quadratus lumborum block (QLB) has an opioid sparing effect. The aim of this study was to further evaluate the effect of opioid-free anesthesia (OFA) combined with regional block on the quality of recovery in patients undergoing retroperitoneoscopic renal surgery. METHODS: Sixty patients undergoing elective retroperitoneoscopic renal surgery were divided into the opioid-free anesthesia with quadratus lumborum block group (OFA group, N.=30) and opioid anesthesia with quadratus lumborum block group (OA group, N.=30) using the random number table method. The main outcome measures were the quality of recovery assessed by Quality of Recover-40 (QoR-40) at the 24th postoperative hour. Secondary outcomes were postoperative pain score, postoperative opioid consumption, postoperative nausea and vomiting, time to ambulate, and time to readiness for discharge. RESULTS: The QoR-40 score on the first postoperative day was significantly higher in the OFA group than that in the OA group (175.41±6.74 vs. 165.07±4.55; P<0.05). OFA also significantly reduced postoperative pain (P<0.05) and morphine consumption at both the 24th and 48th postoperative hour (P<0.05), as well as time to ambulate, and time to readiness for discharge (P<0.05). CONCLUSIONS: OFA with regional block is superior to opioid anesthesia with regional block in the quality of recovery after retroperitoneiscopic renal surgery.
