A randomized trial to assess the effect of cricoid displacing maneuver on the success rate of blind placement of double-lumen tube and Univent bronchial blocker.
Annals of palliative medicine, 2021Co-Authors: Yuting Luo, Cheng Zhou, Peng LiangAbstract:Background Double lumen tube (DLT) and Univent are two commonly used lung isolation devices that often require bronchoscopy assistance. In order to facilitate blind placement for situations where bronchoscopy was unavailable, the cricoid displacing maneuver (CDM) was adopted. This study was designed to explore whether the CDM could improve the successful blind placement rate in left lung isolation esophageal surgeries. Methods 120 ASA 1-3 patients who received left lung isolation esophageal surgeries from October 2014 to February 2016 and October 2018 to January 2020 were enrolled in this single-centered prospective assessorblinded randomized controlled trial. After anesthesia induction, patients were intubated either with DLT or Univent by applying the CDM, and the position of devices was checked by bronchoscopy. After turning into the right decubitus position, the devices were pulled back to the trachea, and placement was conducted once again. Successful placement rate for the first attempt, time needed for initial placement, malposition and reposition times by bronchoscopy during surgery, Bronchus Injury score, rank of lung isolation and postoperative anesthesia-related complications were recorded. Results At supine position, the successful placement rates for the first attempt of DLT-CDM, DLTcontrol, Univent-CDM and Univent-Control were 100%, 76.7%, 96.7% and 66.7% respectively (DLT: P=0.016; Univent: P=0.003) while at right decubitus position were 86.7%, 66.7%, 93.3% and 66.7% (DLT: P=0.067; Univent: P=0.010). There was no significant difference in the time needed for successful intubation and no severe complications. Conclusions The current study provided evidence that the CDM is an effective and safe blind endobronchial placement technique for left DLT and Univent. We suggest that CDM could be applied to the endobronchial placement of left DLT and Univent.

efficacy of a new blind insertion technique of arndt endobronchial blocker for lung isolation comparison with conventional bronchoscope guided insertion technique a pilot study
Medicine, 2016Co-Authors: Peng Liang, Juan Ni, Cheng Zhou, Hai YuAbstract:This study aimed to find other methods of blind insertion of Arndt endobronchial blocker (AEB) for lung isolation when a fiberoptic bronchoscope (FOB) is unavailable. We compared the effectiveness and safety of 3 insertion techniques of AEB: Gum elastic bougie (GEB)-, bougie combined with cricoid displacing (BCD)-, and fiberoptic bronchoscope (FOB)-guided insertion. Seventy-eight patients undergoing esophageal procedure and requiring left thoracotomy were randomly assigned to 1 of 3 groups: GEB group, BCD group, and FOB group. We recorded the successful placement of AEBs at first attempt, placement time, malposition of AEBs in supine and lateral decubitus position, the Bronchus Injury score, and other complications. The successful placement of AEB for the first attempt was 22/26, 25/26, and 26/26 patients in GEB, BCD, and FOB groups, respectively. The placement times in GEB and BCD groups were longer than those in the FOB group (P 0.05). Bougie and cricoid displacing-guided blind insertion of AEB seems to be a novel method, which is an effective and safe alternative when FOB was unavailable.

Unplanned Conversion to Thoracotomy During Video-Assisted Thoracic Surgery Lobectomy does not Compromise the Surgical Outcome
World Journal of Surgery, 2011Co-Authors: Joon Suk Park, Hong Kwan Kim, Yong Soo Choi, Jhingook Kim, Young Mog Shim, Kwhanmien KimAbstract:Background Concerns remain unresolved regarding the safety of unplanned conversion to open thoracotomy during video-assisted thoracic surgery (VATS) lobectomy. We analyzed both early and late outcomes after thoracotomy conversion from VATS. Methods From December 2003 to December 2008, a total of 738 VATS lobectomies were attempted. Among them were 34 unplanned conversions to open thoracotomy. Patient characteristics, operative data, and early and late postoperative outcomes were analyzed retrospectively. Results Among the 34 conversion cases, 26 patients had lung cancer and 8 had benign lung disease. The conversion rate was 4.61%. Left and right upper lobectomies were most often associated with unplanned conversions. Conversion was classified into five groups: (1) problems related to anthracofibrosis of hilar lymph nodes in 14 patients; (2) intraoperative vessel or Bronchus Injury in 11 patients; (3) fused interlobar fissure in 4 patients; (4) oncologic problems, including mediastinal or hilar lymph node metastasis in 2 patients; and (5) vascular anomalies in 3 patients. There was one death due to postoperative pneumonia in a patient with multiple co-morbidities. Two patients had an episode of pneumonia. The mean hospital stay was 10 days, and the median follow-up period was 30.0 ± 11.47 months. Three patients with lung cancer developed recurrent disease, all of whom were found to have stage III disease. No cancer-related death occurred. There was no significant difference in survival or recurrence between patients with conversion and those with successful VATS. However, the operating time and hospital stay were significantly longer in conversion patients. Conclusions Our data support the claim that VATS lobectomy can be safely performed with an acceptable conversion rate. Unplanned conversion to open thoracotomy does not appear to compromise the prognosis.
