Transcript of 4. Vats and Post Op Care
Video-Assisted ThoracoscopicSurgery (VATS)
By: Kim Patrick S.P. Marallag
Video Assisted Thoracoscopic Surgery (VATS)
• Diagnosis and treatment of pleural effusions and recurrent pneumothorax, and for lung biopsy, lobectomy or segmental resection, resection of bronchogenic and mediastinal cysts, esophageal myotomy, and intrathoracic esophageal mobilization for esophagectomy.
VATS…
• Performed via two to four incisions measuring 0.5 to 1.2 cm in length to allow insertion of the thoracoscope and instruments.
• Endoscopic staplers are used to divide the major vascular structures and bronchus.
VATS…
• Examples of VAST lobectomy maneuvers done with the pt in left lateral decubitus position
VATS…
• At the conclusion of a thoracic operation:- Chest tube placement
not needed if pleural viscera is not violated
- Positive pressure ventilationto re-expand the lungs
Post Operative CareChest Tube2 purposes:- For air evacuation- For blood and
pleural fluid drainage
- The ability of the pleural lymphatics to absorb fluid is substantial. It can be as high as 0.40 mL/kg per hour in a healthy individual, possibly resulting in the absorption of up to 500 mL of fluid over a 24-hour period.
- pleural tubes can be removed after VATS lobectomy or thoracotomy with 24-hour drainage volumes as high as 400 mL without subsequent development of pleural effusions.
- If the pleural space is altered, strict adherence to a volume requirement before tube removal is appropriate.
- The use of suction and the management of air leaks vary.
- To eradicate residual air spaces and to control postoperative parenchymal air leaks, suction level of -20 H2O have been commonly used.
Evaluation of an air leak and/or incompletely drained pneumothorax with associated pulmonary collapse
- Check for tube patency- Ask patient to cough or perform valsalva
maneuver- During the cough, the water seal chamber is
observed. ( bubbles = air leaks ) , (stationary fluid level = mech. blockade )
Pain ControlThe most common routes for pain medication
are:EpiduralParavertebralIV
Epidural anesthesiainserted at about the T6 level, roughly at
the level of the scapular tip. Fentanyl with bupivacaine
or robivacaine urinary retention
Paravertebral anesthesia2.5 cm lateral to the
spinous process at T4 to T6
narcotics with topical analgesicsLocal anesthesia may cause
hypotension or vasodilation
IV narcoticsoften in conjunction with ketorolacOversedation and narcotization of patientsrisk of secretion retention and development of
atelectasis or pneumonia
• The patient typically is transitioned to oral pain medication on the third or fourth postoperative day.
• During both the parenteral and oral phase of pain management, use of a standardized regimen of stool softeners and laxatives is advisable to prevent severe constipation.
Respiratory Care- Patient should be able to deliver an effective
cough, if it is impossible to cough, use of suction is required to remove secretions.
- Preoperatively, give instructions of applying pressure over the wound
- Postoperatively, proper pain control without over sedation is essential.
