Background and study aims
Fast-track surgery represents a new approach optimizing surgical care including patient management before, during and after surgery. Even nowadays, in the era of minimally invasive interventions, thoracic (chest) surgery often causes severe pain afterward, which can significantly affect recovery, the patient’s return to daily activities and the final outcome. There is still not enough evidence of the effectiveness of the transdermal fentanyl patch (TFP) in patients undergoing minimally-invasive thoracic surgery. As pain control remains an important challenge to the surgeon and to health care systems, clinical studies are required to find the best method of pain relief after surgery. The aim of this study is to find out whether using TFP within the concept of fast-track surgery helps with patient recovery, is safe and improves pain control during hospital stay and after discharge.

Who can participate?
Patients aged 18 and over undergoing lung resection by video-assisted thoracoscopic surgery (VATS)

What does study involve?
One day before surgery patients are randomly allocated receive a patch either with fentanyl or without it (placebo) applied on the shoulder skin and covered with neutral skin dressing. Patients are asked to evaluate pain intensity on a scale from 0 to 10 before surgery, directly after the surgery, 3-5 hours later, on the first and second day after and on the day of discharge. Patients are also called after discharge to ask about pain severity on the next day after discharge and 30 days after discharge. Patients are also asked about side effects (nausea, vomiting, and others). Apart from the study drug patients also receive standard combined pain relief, so that placebo group patients (without fentanyl patch) receive adequate pain relief in the same manner as the treatment group patients.

What are the possible benefits and risks of participating?
The results of this study may help health providers to decrease pain in patients undergoing this type of surgery, as well as to ensure faster and easier recovery. As with as any other drug, fentanyl can cause some side effects as nausea, vomiting, confusion, respiratory depression (slow breathing) and allergic reactions.

Study typeQuality of life
Scientific titleRandomized clinical trial of transdermal fentanyl patch as part of fast-track thoracic surgery postoperative pain management protocol
Study objectivesUse of transdermal fentanyl patches facilitates recovery after video-assisted thoracoscopic surgery (VATS) enabling more stable and efficient postoperative pain control during hospital stay and after discharge.
Ethics approval(s)Pauls Stradins Clinical University Hospital ethics committee, 23/04/2018, Nr. 230418-26L
Health condition(s) or problem(s) studiedPostoperative pain intensity in patients after video-assisted thoracoscopic surgery
InterventionSimple randomization based on a single sequence of random assignments, allocation ratio 1:1. After randomization patients will be allocated to two groups: transdermal fentanyl patch group (TFP) and placebo group (P). The TFP group will receive a long-acting (72 hours) low dose (25 µg/hr) transdermal fentanyl patch. Placebo group patients will receive a similar looking patch without any active substance applied at the same time as for the TFP group patients. Patches will be applied on the shoulder skin and covered with neutral skin dressing in both group. All patches will be replaced every 72 hours and on the day of discharge unless there are side effects. At the end of surgery both groups will receive an intercostal nerve block with 20 ml of 0.25 % bupivacaine solution. Postoperatively both groups receive standard postoperative care and multimodal analgesia with acetaminophen 1 g three times a day and lornoxicam 8 mg two times a day for baseline pain control. Postoperative combined analgesia also includes trimeperidine 20 mg when necessary (0-4 times a day) for breakthrough pain. All patients receive 20 ml of lactulose oral solution per day as prophylaxis of opioid-related constipation. After discharge patients will be prescribed oral codeine 60 mg in combination with acetaminophen 1 g three to four times a day or when necessary.

PhaseNot Applicable
Drug / device / biological / vaccine name(s)Fentanyl
Primary outcome measureIntensity of postoperative pain assessed by visual analogue pain scale (VAS) and scored on a numeric rating scale from 0 (no pain) to 10 (the worst imaginable pain). Assessed before surgery, directly after the surgery, 3-5 hours later, on the first and second postoperative day and on the day of discharge. After discharge patients will be followed-up twice by telephone to assess pain severity on the next day after discharge and 30 days after discharge.
Secondary outcome measures1. Presence of nausea or vomiting, signs of respiratory depression and confusion, assessed by asking before surgery, directly after the surgery, 3-5 hours later, on the first and second postoperative day, on the day of discharge, as well as on the next day after discharge and 30 days after discharge
2. Requirement of rescue medication (trimeperidine) for breakthrough pain, length of postoperative hospital stay and duration of chest drainage collected from patients' history on the day of discharge
