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. 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.

  • Nicotine Dependence
  • Thoracic Diseases
  • Analgesia

Interventions

DRUG

Nicotine patch

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)
