The rapid development and promotion of minimally invasive thoracic surgery represented by video-assisted thoracoscopy surgery has gradually replaced traditional thoracic surgery technique as the primary choice for the treatment of pulmonary nodules, including early lung cancer. With the clinical application of double-lumen bronchial catheters, the realization of one-lung ventilation technology not only provides a solid anesthesia foundation for the popularization of minimally invasive thoracic surgery, but also provides a guarantee for the rapid and smooth implementation of the operation. However, compared with single-lumen bronchial catheters, the diameter of the double-lumen bronchial catheter is thicker, and the tube body is hard and difficult to shape, which brings inconvenience to anesthesia intubation. The bronchial structure is different, and the incidence of dislocation during anesthesia intubation is also high. With the gradual clinical use of video double-lumen tube (VDLT), it has become a hot spot in thoracic surgery in recent years. This article reviews the application and research progress of VDLT in thoracic surgery.

BACKGROUND: As lung ultrasound (LUS) can be used to identify regional lung ventilation and collapse, we hypothesize that LUS can be better than auscultation in assessing lung isolation and determining double lumen tube (DLT) position. METHODS: A randomized controlled study was conducted in tertiary care cancer institute from November 2014 to December 2015, including 100 adult patients undergoing elective thoracic surgeries. Patients with tracheostomy, difficult airway and pleural-based pathologies were excluded. After anesthesia induction and DLT insertion, patients were randomized into group A (auscultation) and group B (LUS). Regional ventilation was assessed by experienced anesthesiologists using the respective method for each group. Final confirmation of DLT position with a bronchoscope was performed by a blinded anesthesiologist. Contingency tables were plotted to determine sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for each method. RESULTS: Data from 91 patients were analyzed (group A = 47, group B = 44). Compared with auscultation, LUS had significantly higher sensitivity (94.1% vs. 73.3%, P = 0.010), PPV (57.1% vs. 35.5%, P = 0.044), NPV (93.8% vs. 75.0%, P = 0.018), accuracy (70.5% vs. 48.9%, P = 0.036) and required longer median time (161.5 vs. 114 s, P < 0.001) for assessment of DLT position. Differences in specificity (55.6% vs. 37.5%, P = 0.101) and area under curve (0.748; 95% CI: 0.604–0.893 vs. 0.554, 95% CI: 0.379–0.730; P = 0.109) were not significant. CONCLUSIONS: Compared to auscultation, LUS is a superior method for assessing lung isolation and determining DLT position.

In video-assisted thoracoscopic surgery (VATS), general anesthesia with endotracheal intubation was considered an optimal method of anesthesia for a long time. However, complications due to general anesthesia and one-lung ventilation have become a problem. In recent years, epidural anesthesia without endotracheal intubation has been attempted in various thoracic surgical procedures with various advantages and disadvantages reported. We compared postoperative pain and prognosis when different anesthesia methods were used in a patient who underwent the same operation twice in the interval of one year. When non-intubated video-assisted thoracoscopic surgery (NIVATS) underwent under epidural anesthesia, postoperative pain score was lower, adverse events were fewer, and the hospital stay was shorter than that of VATS. The patient also expressed high subjective satisfaction. Like previous studies, the results favored NIVATS under epidural anesthesia. However, greater attention and proficiency are required from the anesthesiologist for proper analgesia and sedation.

OBJECTIVETo assess the feasibility and safety of thoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation.
METHODSSixty patients with pulmonary bulla were randomized into two groups (n=30) to undergo video-assisted thoracoscopic surgery (VATS) for bulla resection with laryngeal mask anesthesia and high-frequency low tidal volume lung ventilation general anesthesia and or with intubation anesthesia and one-lung ventilation through double-lumen endotracheal intubation.
RESULTSNo significant differences were found in anesthesia time, surgery time, intraoperative lowest SpO2, intraoperative highest PetCO2, operative field, anesthetic effects, or blood loss between the two groups. The post-operative WBC and NEU% showed significantly smaller increments in the mask anesthesia group than in the intubation group, and the postoperative awake time, initial eating time, ambulation time, in-hospital stay, and drainage time were significantly shortened in the former group with also lower incidences of gastrointestinal reactions, throat discomfort and hoarseness.
CONCLUSIONThoracoscopic bulla resection under laryngeal mask anesthesia with low tidal volume high-frequency lung ventilation is safe and feasible and results in better patient satisfaction and shorter in-hospital stay than procedures performed under intubation anesthesia with one-lung ventilation.

PURPOSE: Hypoxemia during one-lung ventilation (OLV) remains a serious problem, particularly in the supine position. We investigated the effects of alveolar recruitment (AR) and positive end-expiratory pressure (PEEP) on oxygenation during OLV in the supine position. MATERIALS AND METHODS: Ninety-nine patients were randomly allocated to one of the following three groups: a control group (ventilation with a tidal volume of 8 mL/kg), a PEEP group (the same ventilatory pattern with a PEEP of 8 cm H2O), or an AR group (an AR maneuver immediately before OLV followed by a PEEP of 8 cm H2O). The tidal volume was reduced to 6 mL/kg during OLV in all groups. Blood gas analyses, respiratory variables, and hemodynamic variables were recorded 15 min into TLV (TLVbaseline), 15 and 30 min after OLV (OLV15 and OLV30), and 10 min after re-establishing TLV (TLVend). RESULTS: Ultimately, 92 patients were analyzed. In the AR group, the arterial oxygen tension was higher at TLVend, and the physiologic dead space was lower at OLV15 and TLVend than in the control group. The mean airway pressure and dynamic lung compliance were higher in the PEEP and AR groups than in the control group at OLV15, OLV30, and TLVend. No significant differences in hemodynamic variables were found among the three groups throughout the study period. CONCLUSION: Recruitment of both lungs with subsequent PEEP before OLV improved arterial oxygenation and ventilatory efficiency during video-assisted thoracic surgery requiring OLV in the supine position.

6.Effects of different ventilation modes for one-lung ventilation anesthesia on respiratory function and F(A)/F(I) changes during sevoflurane inhalation.
Journal of Southern Medical University 2011;31(4):714-717
OBJECTIVETo investigate the effects of different ventilation modes for one lung ventilation anesthesia on arterial blood-gas, airway pressure, intrapulmonary shunt, and F(A)/F(I) changes in patients receiving sevoflurane inhalation.
METHODSThirty ASA class II-III patients with lung cancer undergoing pulmonary lobectomy were randomized into 3 equal groups. The patients in group A received volume-controlled ventilation (VCV) without positive end-expiratory pressure (PEEP) (VT=8 ml/kg, Rf=12/min), and those in group B, after a preceding VCV stabilize the airway pressure, had pressure-controlled ventilation with maintenance of an identical peak pressure (Ppeak) (Rf=12/min, PEEP=0). In group C, the patients received small tidal volume ventilation with PEEP (VT=6 ml/kg, Rf=16/min, PEEP=5 cm H(2)O). Blood gas analysis was carried out at 10 min after TLV and at 20, 45 and 70 min after one lung ventilation (OLV); the heart rate (HR), mean arterial pressure (MAP), SpO(2) and Ppeak were also recorded and blood samples collected from the artery and jugular vein at these time points. Inhalation of 1.5% sevoflurane for 20 min started at 20 min of OLV.
RESULTSCompared with those in TLV, the Ppeak increased, lung compliance decreased, arterial oxygenation (PaO(2)) decreased and intrapulmonary shunt (Qs/Qt) increased during OLV. Group B showed the fastest increase of F(A)/F(I) in the initial 8 min, followed by groups A and C, but the curves became similar with the passage of time.
CONCLUSIONSDuring OLV, the 3 ventilation modes result in similar F(A)/F(I) changes during sevoflurane inhalation but PCV can increase pulmonary compliance.

BACKGROUND: Surgical correction needs to be considered when diaphragm eventration leads to impaired ventilation and respiratory muscle fatigue. Plication to sufficiently tense the diaphragm by VATS is not as easy to achieve as plication by open surgery. We used pneumatic compression with carbon dioxide (CO2) gas in thoracoscopic diaphragmatic plication and evaluated feasibility and efficacy. METHODS: Eleven patients underwent thoracoscopic diaphragmatic plication between January 2008 and December 2013 in Pusan National University Hospital. Medical records were retrospectively reviewed, and compared between the group using CO₂ gas and group without using CO2 gas, for operative time, plication technique, duration of hospital stay, postoperative chest tube drainage, pulmonary spirometry, dyspnea score pre- and postoperation, and postoperative recurrence. RESULTS: The improvement of forced expiratory volume at 1 second in the group using CO₂ gas and the group not using CO₂ gas was 22.46±11.27 and 21.08±5.39 (p=0.84). The improvement of forced vital capacity 3 months after surgery was 16.74±10.18 (with CO₂) and 15.6±0.89 (without CO₂) (p=0.03). During follow-up (17±17 months), there was no dehiscence in plication site and relapse. No complications or hospital mortalities occurred. CONCLUSION: Thoracoscopic plication under single lung ventilation using CO₂ insufflation could be an effective, safe option to flatten the diaphragm.
