The Change in Pulse Rate and Behavioral Score by Using Video Assisted Induction of Pediatric Anesthesia

Purpose: Objective of this study was to determine whether video assisted anesthesia induction reduced pediatric patients’ stress. Methods: With approval from the local ethics committee and parental informed consent, 75 children undergoing minor surgery were investigated in this prospective observational study. Patients were divided into three groups: group 1 was aged two to three years old, group 2 was aged four to six years old and group 3 was aged from seven to ten years old. The following three characteristics were evaluated: 1) the pulse rate at four points (the ward, the entrance at the operating room, mask notification and the mask fit);2) the behavioral score in the operating room;3) the amount of pain killers after the operation. Results: In group 1 (N = 20), there was a significant difference between the control group and the video assisted group regarding the percentage change in pulse rate based on the children’s ward when the patients looked at the mask. In group 2 (N = 26), there was no significant difference regarding any points. In group 3 (N = 29), there was a significant difference between control and video assisted group regarding the percentage change in pulse rate based on the children’s ward for all points. Also, regarding to the behavioral score, there was a significant difference between the control group and the video assisted group of all ages. However, there was no significant difference regarding the use of NSAIDs in the postoperative period between the control and the video assisted group. Conclusion: These results show that the video assisted anesthesia induction is effective for pediatric patients.

Effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery

Objective:The aim of this study was to observe the effect of endobronchial blocker tube in the pulmonary carcinoma with video-assisted thoracic surgery.Methods:Forty patients of pulmonary carcinoma with video-assisted thoracic surgery were randomly assigned into two groups with twenty cases each:endobronchial blocker tube group(group 1) and double-lumen endobronchial tube group(group 2).After anesthesia was induced,in group 1,single lumen tube was intubated at first,and then endobronchial blocker tube intubated to left or right primary bronchus under the guidance of fiber-optic bronchoscope according to operational necessary,injected 2-4 mL air to blocker balloon and blocker one lateral primary bronchus for one-lung ventilation necessarily;while in group 2,the position of double-lumen endobronchial tube was confirmed with fiber-optic bronchoscope after intubation.Blood samples were collected before anesthesia induction,double lumen ventilation,at the one-lung ventilation of 5 min,30 min,60 min,120 min and 180 min,SBP,DBP,HR,SpO2,partial pressure of end tidal carbon dioxide(PetCO2),pH,PaO2,PaCO2,PaO2/FiO2 were recorded.Results:Forty cases' intubations were all successful.There were no differences in SBP,DBP,HR,SpO2,PetCO2,pH,PaCO2 between two groups in different points(P > 0.05).Paw in group 1 was lower than group 2,PaO2 and PaO2/FiO2 in group 1 was higher than group 2 in the one lung ventilation of 5 min,30 min,60 min,120 min and 180 min.Conclusion:The endobronchial blocker tube can meet the request of video-assisted thoracic surgery,with the special advantages of simple insertion,lower airway and better oxygenation.Endobronchial blocker tube offer a new way for one-lung ventilation in the pulmonary carcinoma with video-assisted thoracic surgery.

Simultaneous lateral and subxiphoid access methods for safe and accurate resection of a superior vena cava aneurysm:A case report

BACKGROUND Superior vena cava(SVC)aneurysms are a relatively uncommon disease that has not been widely reported.The conventional surgical approach for treating SVC aneurysms includes open thoracotomy and mid-sternotomy.However,in this case,the aneurysm could be safely resected by thoracoscopic simultaneous lateral and subxiphoid access methods.CASE SUMMARY A 58-year-old male presented with intermittent chest pain and persistent discomfort in the chest area.A chest computed tomography scan revealed a 6.2 cm aneurysm in the left innominate vein and SVC junction.For surgical resection,simultaneous lateral and subxiphoid access were planned to achieve optimal proximal and distal aneurysm control.The approach site was 1 cm below the xiphoid process,the fifth mid-axillary line and the seventh anterior axillary line on the right side.The aneurysm was resected using a stapler.The patient was discharged on the third day after chest tube removal on the second postoperative day with no particular issues.CONCLUSION Aneurysms located within the mediastinum can be accessed through thoracoscopic approach without open surgery and safely resected using vascular staples.
