Trial summary

Globally, approximately 230 million adults undergo surgical procedures each year, with around 30% of patients maintaining smoking habits prior to surgery. Extensive clinical research has confirmed that tobacco exposure is a significant independent risk factor for perioperative complications. Read more about this study

About this study

Globally, approximately 230 million adults undergo surgical procedures each year, with around 30% of patients maintaining smoking habits prior to surgery. Extensive clinical research has confirmed that tobacco exposure is a significant independent risk factor for perioperative complications. Epidemiological data indicate that long-term smokers experience a significantly higher all-cause mortality rate during hospitalization, approximately 20% greater than non-smokers, while the incidence of postoperative complications is 40% higher. Consequently, international guidelines universally recommend the establishment of standardized preoperative smoking cessation programs for surgical patients. Nicotine withdrawal, a typical clinical manifestation during smoking cessation, involves symptoms across multiple systems: neuropsychiatric symptoms such as mood depression, sleep disturbances, and irritability; autonomic dysfunction leading to postural dizziness and bradycardia; and metabolic dysregulation resulting in increased appetite and weight gain. Notably, these withdrawal symptoms exhibit a significant time-dependent pattern, typically peaking 24-72 hours after cessation. Multicenter studies have demonstrated that tobacco-dependent patients experience an average increase of IV Abstract 35-45% in opioid consumption within 24 hours postoperatively, with the duration of analgesic requirements extended by approximately 25%. However, some patients suffer from severe adverse reactions to opioids (e.g., nausea, vomiting, confusion), making the use of adjuvant medications for multimodal analgesia and optimized pain management particularly crucial. By the late 20th century, the analgesic properties of nicotine, a primary component of tobacco, were systematically studied and applied in clinical practice.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nicotine patchDrug

    Based on analgesia in the control group, the patients were given a nicotine patch every day, 24 hours before surgery and 48 hours after surgery, placed on the patient's arm, chest, or back, and the skin was cleaned before the patch. Different doses of nicotine patches are given depending on the number of cigarettes smoked by the patient (one 21 mg patch for every 20 cigarettes, 42 mg patch for patients who smoke ≥ 40 cigarettes per day)

Nicotine patch group (group N)ExperimentalBased on analgesia in the control group, the patients were given a nicotine patch every day, 24 hours before surgery and 48 hours after surgery, placed on the patient's arm, chest, or back, and the skin was cleaned before the patch. Different doses of nicotine patches are given depending on the number of cigarettes smoked by the patient (one 21 mg patch for every 20 cigarettes, 42 mg patch for patients who smoke ≥ 40 cigarettes per day)
Receives: Drug: Nicotine patch
Control group (Group C)No interventionOn the basis of conventional analgesia, patients were given a placebo patch without any drug effect every day 24 hours before surgery and 48 hours after surgery, and the shape, weight, and position of the patch were consistent with those of the experimental group

Questions about this trial

What is this clinical trial studying?

A study testing Nicotine patch in people with Nicotine Dependence and Thoracic Diseases, run by Henan Provincial People's Hospital at 1 site in China.

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 6 inclusion and 7 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: looking for participants now, as of the sponsor's last update on 22 Jan 2026. 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 China. 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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

Contact Wei Li (+8619838263779, 1131691709@qq.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Analgesic pump dosage in (ml) for Postoperative pain (time frame: 48 hours). 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 22 Jan 2026.
