OBJECTIVE: Lung biopsies are sometimes performed in mechanically ventilated patients with acute hypoxemic respiratory failure (AHRF) of unknown etiology to guide patient management. While surgical lung biopsies (SLB) offer high diagnostic rates, they may also cause significant complications. Transbronchial forceps lung biopsies (TBLB) are less invasive but often produce non-contributive specimens. Transbronchial lung cryobiopsies (TBLC) yield specimens of potentially better quality than TBLB, but due to their novel implementation in the intensive care unit (ICU), their accuracy and safety are still unclear.
OBJECTIVE: Our main objective was to evaluate the risk of adverse events in patients with AHRF following the three biopsy techniques. Our secondary objectives were to assess the diagnostic yield and associated modifications of patient management of each technique.
METHODS: We conducted a retrospective cohort study comparing TBLC, TBLB, and SLB in mechanically ventilated patients with AHRF.
METHODS: The primary outcome was the proportion of patients with at least one complication, and secondary outcomes included complication rates, diagnostic yields, treatment modifications, and mortality.
RESULTS: Of the 26 patients who underwent lung biopsies from 2018 to 2022, all TBLC and SLB patients and 60% of TBLB patients had at least one complication. TBLC patients had higher unadjusted numbers of total and severe complications, but also worse Sequential Organ Failure Assessment scores and P/F ratios. A total of 25 biopsies (25/26, 96%) provided histopathological diagnoses, 88% (22/25) of which contributed to patient management. ICU mortality was high for all modalities (63% for TBLC, 60% for TBLB and 50% for SLB).
CONCLUSIONS: All biopsy methods had high diagnostic yields and the great majority contributed to patient management; however, complication rates were elevated. Further research is needed to determine which patients may benefit from lung biopsies and to determine the best biopsy modality.

BACKGROUND: Video-assisted thoracoscopic surgery (VATS) often induces significant postoperative pain, potentially leading to chronic pain and decreased quality of life. This study aimed to evaluate the acetaminophen/ibuprofen combination effectiveness in reducing analgesic requirements and pain intensity in patients undergoing VATS.
METHODS: This is a double-blinded randomized controlled trial.
METHODS: Adult patients scheduled for elective VATS for lung resection were randomized to receive either intravenous acetaminophen and ibuprofen (intervention group) or 100 mL normal saline (control group). Treatments were administered post-anesthesia induction and every 6 h for three cycles. The primary outcome was total analgesic consumption at 24 h postoperatively. Secondary outcomes were cumulative analgesic consumption at 2 and 48 h; analgesic-related side effects at 2, 24, and 48 h; quality of recovery at 24 h and 48 h postoperatively; pain intensity at rest and during coughing; and rescue analgesics use. Chronic postsurgical pain (CPSP) was assessed through telephone interviews 3 months postoperatively.
RESULTS: The study included 96 participants. The intervention group showed significantly lower analgesic consumption at 24 h and 48 h postoperatively (24 h: median difference: - 100 µg equivalent intravenous fentanyl [95% confidence interval (CI) - 200 to - 5 μg], P = 0.037; 48 h: median difference: - 140 μg [95% CI - 320 to - 20 μg], P = 0.035). Compared to the controls, the intervention group exhibited a significantly lower quality of recovery 24 h post-surgery, with no significant difference at 48 h. All pain scores except for coughing at 48 h post-surgery were significantly lower in the intervention group compared to the controls. No significant differences were observed between the groups in postoperative nausea and vomiting occurrence, hospital stay length, and CPSP.
CONCLUSIONS: Perioperative administration of acetaminophen/ibuprofen significantly decreased analgesic needs in patients undergoing VATS, providing an effective postoperative pain management strategy, and potentially minimizing the need for stronger analgesics.

BACKGROUND: Regional block, such as thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), or serratus anterior plane block (SAPB) has been recommended to reduce postoperative opioid use in recent guidelines, but the optimal options for intraoperative opioid minimization remain unclear. The aim of this study was to evaluate the intraoperative opioids-sparing effects of three regional blocks (TEA, TPVB, and SAPB) in patients undergoing video-assisted thoracoscopic surgery (VATs).
METHODS: This was a retrospective study of the adults undergoing VATs at a tertiary medical center between January 2020 and February 2022. According to the type of regional block used, patients were classified into 4 groups: GA group (general anesthesia without any regional block), TEA group (general anesthesia combined with TEA), TPVB group (general anesthesia combined with TPVB), and SAPB group (general anesthesia combined with SAPB). Cases were matched with a 1:1:1:1 ratio for analysis by age, sex, ASA physical status, and operation duration. The primary outcome was the total intraoperative opioid consumption standardized to Oral Morphine Equivalents (OME). Multivariable linear regression was used to estimate the association of the three regional blocks with the OME.
RESULTS: A total of 2159 cases met the eligibility criteria. After matching, 168 cases (42 in each group) were included in analysis. Compared with GA without any reginal block, the use of TEA, TPVB, and SAPB reduced the median of intraoperative OME by 78.45 mg (95% confidence interval [CI], -141.34 to -15.56; P = 0.014), 94.92 mg (95% CI, -154.48 to -35.36; P = 0.020), and 11.47 mg (95% CI, -72.07 to 49.14; P = 0.711), respectively.
CONCLUSIONS: The use of TEA or TPVB was associated with an intraoperative opioid-sparing effect in adults undergoing VATs, whereas the intraoperative opioid-sparing effect of SAPB was not yet clear.

Background: Video-assisted thoracoscopic surgery is a widely recommended treatment for empyema in advanced stages. However, only a few studies have evaluated prognostic factors among patients with empyema who underwent video-assisted thoracoscopic surgery. Furthermore, no studies have evaluated predictors of direct discharge home. Patients and Methods: This multicenter retrospective cohort study included 161 patients with empyema who underwent video-assisted thoracoscopic surgery in five acute-care hospitals. The primary outcome was the probability of direct discharge home. The secondary outcome was the length of hospital stay after surgery. We broadly assessed pre-operative factors and performed univariable logistic regression for the direct discharge home and univariable gamma regression for the length of hospital stay after surgery. Results: Of the 161 included patients, 74.5% were directly discharged home. Age (>70 years; -24.3%); altered mental status (-33.4%); blood urea nitrogen (>22.4 mg/dL; -19.4%); and pleural pH (<7.2; -17.6%) were associated with high probabilities of not being directly discharged home. Fever (15.2%) and albumin (> 2.7 g/dL; 20.2%) were associated with high probabilities of being directly discharged home. The median length of stay after surgery was 19 days. Age (>70 years; 6.2 days); altered mental status (5.6 days); purulence (2.7 days); pleural thickness (>2 cm; 5.1 days); bronchial fistula (14.6 days); albumin (>2.7 g/dL; 3.1 days); and C-reactive protein (>20 mg/dL; 3.6 days) were associated with a longer post-operation hospital stay. Conclusions: Physicians should consider using these prognostic factors to predict non-direct discharge to the home for patients with empyema.

BACKGROUND: Postoperative nausea and vomiting (PONV) is a common complication after general anaesthesia and is associated with morbidity and prolonged length of stay. Growing evidence suggest that opioid-free general anaesthesia (OFA) may reduce PONV in various surgical settings. We aim to evaluate the efficacy of OFA on the incidence of PONV compared with opioid-based anaesthesia among adults undergoing thoracoscopic surgery.
METHODS: This is a prospective, single-centre, randomised controlled trial comparing OFA and opioid-based anaesthesia for thoracoscopic surgery. A total of 168 adults will be randomised with a 1:1 ratio to receive either opioid-free anaesthesia or opioid-based anaesthesia. The primary outcome will be the incidence of PONV within 24 h after operation. The secondary outcomes will include the severity of PONV, quality of recovery, pain at rest, 6-min walking test, and health-related quality of life after operation.
CONCLUSIONS: The benefit-risk of OFA for patients after operation is contradictory in previous studies, so further study is required. This trial will focus on the effect of OFA on the incidence of PONV in patients undergoing thoracoscopic surgery. This trial adopts uniformed PONV and perioperative pain management, standardised randomised and blind, clear-cut inclusion and exclusion criteria, and standardised scales to assess the severity of PONV after surgery, the quality of postoperative recovery, and the health status at 6 months. The findings of this study will help to provide references to promote early recovery of patients after lung surgery.

UNASSIGNED: Spontaneous pneumothorax is a potentially fatal condition with a high risk of recurrence. The purpose of this study is to compare two different approaches to SP management. In the first group, patients underwent only chemical pleurodesis; in the second group, CT-scan, VATS, and then chemical pleurodesis was performed.
UNASSIGNED: This study is a non-randomized clinical trial conducted on 65 patients admitted to Al-Zahra Hospital in Isfahan with a primary complaint of sudden dyspnea and a definitive diagnosis of spontaneous pneumothorax. Two studies compared the main outcomes of recurrence within six months and the time until recurrence.
UNASSIGNED: Age, sex, and BMI were matched between the two study groups. The side of the pneumothorax, smoking history, and pulmonary disease history did not differ significantly (P > 0.05). Pneumothorax recurrence did not differ significantly between the two groups (P: 0.477).
UNASSIGNED: This study demonstrated no distinction between VATS and chemical pleurodesis when using only chemical pleurodesis. However, because numerous studies have suggested that one of these techniques may be beneficial for patients with SP, it is recommended to conduct additional randomized controlled trials (RCTs) with a more detailed plan and more comparable procedures, although it appears that meta-analysis design may be effective given the abundance of available RCT studies.

OBJECTIVE: To compare the analgesic efficacies of erector spinae plane (ESP) block and thoracic epidural analgesia (TEA) in video-assisted thoracic surgery (VATS).
METHODS: Sixty patients undergoing VATS received patient-controlled TEA with a basal rate of 3 ml/hour (h), a bolus of 3 ml (Group E), or ESP block with programmed intermittent bolus infusions of 15 mL/3 h and a bolus of 5 ml (Group ES) for 2 postoperative days. The primary outcome was to compare pain scores at rest 24 h postoperatively between the 2 groups. Secondary outcomes included NRS score for 48 h, procedural time, dermatomal spread, use of rescue medication, adverse events, and patient satisfaction.
RESULTS: Patients with continuous ESP block had a higher NRS score than those with TEA but no statistical difference at a specific time. The dermatomal spread was more extensive in the TEA group than in the ESP block group (p=0.016); cumulative morphine consumption was higher in the ESP block group (p=0.047). The incidence of overall adverse events in the TEA group was higher than in the ESP block group (p=0.045).
CONCLUSIONS: Erector spinae plane block may be inferior to TEA for analgesia following VATS, but it could have tolerable analgesia and a better side effect profile than TEA. Therefore, it could be an alternative to TEA as a component of multimodal analgesia.

UNASSIGNED: Simultaneous bilateral pulmonary resection via uniportal video-assisted thoracoscopic surgery (UVATS) was safe and feasible for the treatment of bilateral multiple pulmonary nodules. But, it should be noted that considerable postoperative pain at the bilateral surgical site was a crucial issue. The safety and efficacy of bilateral thoracic paravertebral block (TPVB) have been reported for postoperative analgesia. But, whether bilateral sequential TPVB can be safely and effectively used in simultaneous bilateral UVATS remains unknown. Therefore, this study aimed to determine the analgesic efficacy and safety of bilateral sequential TPVB after simultaneous bilateral UVATS.
UNASSIGNED: In this study, 80 participants scheduled for UVATS will be randomly allocated to the bilateral sequential TPVB group (G2) and the control group (G1). The patient of G2 will be performed bilateral TPVB at 2 time-points: before the start of the first side of pulmonary resection and before the start of the contralateral pulmonary resection. G1 will only receive standard analgesia protocol. The primary outcome is the numeric rating scale score during coughing at 24 h postoperatively. The secondary outcomes include the Prince Henry Pain Score scores, sufentanil consumption, postoperative nausea and vomiting, levels of inflammatory factors, and the Quality of Recovery-40 scores at different time points, as well as chronic pain at postoperative day (POD) 90.
UNASSIGNED: This is the first prospective trial to determine the safety and effectiveness of ultrasound-guided bilateral sequential TPVB for postoperative analgesia following simultaneous bilateral UVATS. This study also intended to evaluate the effect of this intervention on postoperative quality of recovery and inflammation levels. The final results will provide clinical evidence related to bilateral sequential TPVB, and promote the application of that acting as a more appropriate analgesic method for simultaneous bilateral UVATS.

Postoperative physical therapy and early mobilization are major elements for enhanced recovery after surgery. In contrast with supervised physical therapy sessions that can be monitored, self-mobilization is not easily quantifiable and has so far been estimated mainly through patient auto-reports. This study aimed to perform a comprehensive and objective evaluation of postoperative mobility.
Prospective observational study.
Postoperative setting.
Patients undergoing mini-invasive lung surgery.
Measurement of postoperative mobility during the first five postoperative days using an accelerometer (ActiGraph GT3X).
The primary outcome was the number of daily steps. Secondary outcomes included physical activity duration and intensity, sedentary time, number of breaks in sedentary time, sedentary patterns, daily evaluation by physiotherapists, postoperative complications, and acceptability of wearing the accelerometer.
Sixty patients were included in the study, of whom 56 provided at least one day of valid accelerometry data. There was no significant change during the first four PODs concerning the number of daily steps nor the mean cadence. One-minute cadence peak, total activity counts, and duration of light-intensity physical activity increased over time (p = 0.032, p = 0.001 and p = 0.001, respectively). Sedentary patterns changed favorably over time, with a decrease in prolonged sedentary bouts (≥ 60 consecutive min) (p < 0.001), and an increase in shorter bouts (< 10 min) (p = 0.001). Similar results were observed when analysis was adjusted for the day of the week when the surgery took place. The median acceptability of wearing the accelerometer was excellent (median 10 [9-10] on a 10-point Likert scale). Three patients had major complications.
Our findings suggest that daily steps may not be the only relevant indicator of early mobility following thoracic surgery and that accelerometry is suitable to follow patients\' early postoperative activity.

BACKGROUND: The aim of this prospective, randomized, controlled study was to evaluate the analgesic effect of ultrasonography (USG) guided continuous erector spinae plane block (ESPB) for postoperative analgesia in video-assisted thoracoscopic surgery (VATS).
METHODS: Eighty American Society of Anesthesiologists (ASA) physical status I-III patients aged 18-75 and who were to undergo VATS were included in this study. Randomization was performed in 2 groups, continuous ESPB (ESPB Group) and no intervention (Control Group). 20 mL of 0.25% bupivacaine was administered for the block. Immediately after surgery, the patient received continuous infusion of 0.125% bupivacaine at 4 mL h-1 via the catheter inserted for the block. Patients in both groups received tramadol via an intravenous patient-controlled analgesia device. Tramadol and meperidine consumption, visual analog scale pain scores and opioid-related side effects were recorded at 0, 1, 4, 8, 12, 24, 36, and 48 h postoperatively.
RESULTS: The use of continuous ESPB in VATS significantly decreased the amount of tramadol used in the first 48 h postoperatively (P < 0.001). There was a statistically significant difference in the number of meperidine rescue analgesia administered between the ESPB and Control Groups (P < 0.001). While the incidences of nausea and itching were higher in Control Group, there were no differences in terms of the other side effects between the groups.
CONCLUSIONS: This study shows that USG-guided continuous ESPB provides adequate analgesia following VATS as part of multimodal analgesia. Continuous ESPB significantly reduced opioid consumption and opioid-related side effects compared to those in the Control Group.
