About this study

Official title: Preoperative Paravertebral Block in Cancer Surgery of the Lung: ParaSOL a Prospective Randomized Controlled Clinical Trial

The investigators aim to determine whether ultrasound-guided preemptive paravertebral blockade (PVB) local anaesthetic (pre-PVB LA), administered in addition to the post-operative PVB (post-PVB) local anaesthetic (LA) infusion, reduces acute postoperative pain, opioid requirement, chronic pain, and improves surgical recovery, in thoracoscopic surgery for lung cancer.

Read the detailed description

In the UK, there has been an increase in lung cancer operations, especially in high risk and elderly patients, improving survival from 10.6% in 2008 to 15.1% in 2013. Lung cancer surgery is associated with severe acute pain, a high incidence of respiratory complications and chronic post-surgical pain. Severe acute postoperative pain is a strong predictor of CPSP. The improvement of perioperative outcomes in elderly patients, the benefits of regional anaesthesia and reduction of chronic pain are investigative priorities of the Anaesthesia and Perioperative Care Setting Partnership.

Enhanced recovery strategies include video-assisted thoracoscopic surgery (VATS), a minimally invasive alternative to open thoracotomy, which may be associated with less postoperative pain. Regional anaesthesia, by thoracic epidural analgesia (TEA) or PVB, is superior to systemic opioids in reducing acute pain after thoracotomy surgery.

Preemptive analgesia describes the aim of minimizing central spinal pain transmission by noxious stimuli arising from events at surgery, by administering an analgesic technique prior to surgical incision. Regional blockade affects central sensitization, allowing analgesia to outlast the pharmacological sensory blockade.

Compared to TEA initiated after surgery, acute pain severity is reduced by preemptive TEA. There are conflicting reports on the benefit of preemptive analgesia in other types of surgery, but TEA and PVB may prevent CPSP in thoracotomy and breast surgery. Some small studies have shown that pre-PVB reduces acute postoperative pain.

Paravertebral blockade is known to be as effective as TEA for acute postoperative analgesia following thoracic surgery, whilst having a lower incidence of pulmonary complications, hypotension and nausea. It is conventional practice in many centres for the surgical administration and placement of a catheter at the end of surgery for postoperative LA infusion (post-PVB) as the sole method of regional analgesia. Preoperative PVB is less common: anaesthetists may use a landmark technique, single or multiple injections and different volumes/strengths of LA.

Ultrasound guidance for pre-PVB injection increases accuracy. In an audit using this technique with post-PVB compared to post-PVB only, the investigators demonstrated reduced pain numerical rating scale (NRS) scores in elective VATS patients, (mean NRS at 24h 2.5 vs 4.5), and a reduction in the proportion of patients who experienced moderate-to-severe pain of NRS≥ 3 from 83% to 50% at 24h.

The investigators therefore aim to evaluate the contribution of ultrasound-guided pre-PVB, administered in addition to the post-PVB LA infusion, in reducing the severity of acute postoperative pain, perioperative opioid requirement, development of CPSP, and improving patient outcome in lung cancer patients undergoing VATS.

Model description
The study will be conducted at Guy's Hospital, London, United Kingdom (UK), a large tertiary thoracic centre for London, Sussex, Kent and Berkshire. In 2015, 459 lung cancer resection operations were performed; 8% of all lung cancer resections in England. Criteria for discontinuation/withdrawal or modifying allocated treatment: * Participant request to withdraw from the study. * Intraoperative identification of infection/tumour in paravertebral space Patient recruitment Eligible patients will be identified in the catchment outpatient clinics 4-6 weeks before surgery. The participant information sheet (PIS) will be introduced in the standard surgical booklet given by the surgeon. At the preoperative assessment clinic 2-3 weeks before surgery, a face-to-face discussion with the research nurse will support the PIS; the opportunity to ask any questions and contact a PPI (Patient and Public Involvement) representative and will be given. Written informed consent will be obtained.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Levo-Bupivacaine Hydrochloride (HCl) 0.5 % in 20mL Injection and 0.9% Sodium Chloride 20mL Injection in people with Thoracic Neoplasm and Chronic Pain Post-Procedural, run by Guy's and St Thomas' NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 29 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Cheng Ong, MBBS (+44 2071887188, cheng.ong@gstt.nhs.uk), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Moderate-to-severe pain Numerical Rating Scale (NRS) >/=3 (time frame: 1 day). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Mar 2024; AzTrials last refreshed its copy on 8 Nov 2026.
