Sex Difference Effects on Postoperative Sleep, Inflammation and Cognition in Patients Undergoing General Anesthesia

September 20, 2021 updated by: Yanchao Yang, Shengjing Hospital
Video-Assisted Thoracoscopic Surgery(VATS) is among the most common and disabling persistent pain and inflammation conditions, with increasing prevalence in the developed world, and affects women to a greater degree than men. And sleep disruption also remains a challenging problem in surgical settings. Postoperative sleep disturbances (POSD) are defined as changes in the sleep structure and quality of patients during the early stages after surgery, which are manifested as significantly shortened rapid eye movement (REM) sleep, prolonged awake time, and sleep fragmentation. Long-term POSD may increase the risk of postoperative delirium or cognitive dysfunction and delay recovery, thereby worsening the patient's physical condition. The aim of the study was to investigate the effect of sex differences on postoperative pain, inflammation, sleep quality and cognitive function among patients who have undergone video-assisted thoracoscopic surgery under general anesthesia.

Conditions

Conditions

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
sleep quality of one night before surgery
Time Frame: one night before surgery
use the athens insomnia scale to evaluate subjective sleep quality (0 to 24 points, with ≥ 6 points indicating a diagnosis of insomnia)
one night before surgery
sleep quality of first night after surgery
Time Frame: first night after surgery
use the athens insomnia scale to evaluate subjective sleep quality (0 to 24 points, with ≥ 6 points indicating a diagnosis of insomnia)
first night after surgery
sleep quality of third night after surgery
Time Frame: third night after surgery
use the athens insomnia scale to evaluate subjective sleep quality (0 to 24 points, with ≥ 6 points indicating a diagnosis of insomnia)
third night after surgery
preoperative inflammation function
Time Frame: three days before surgery
evaluate systemic immune inflammation index (SII) before operation
three days before surgery
preoperative inflammation function
Time Frame: three days before surgery
evaluate neutrophil / lymphocyte ratio (NLR)before operation
three days before surgery
preoperative inflammation function
Time Frame: three days before surgery
evaluate platelet / lymphocyte ratio (PLR) before operation
three days before surgery
preoperative inflammation function
Time Frame: three days before surgery
evaluate monocyte / lymphocyte ratio (MLR) before operation
three days before surgery
postoperative inflammation function
Time Frame: three days after surgery
evaluate systemic immune inflammation index (SII) after operation
three days after surgery
postoperative inflammation function
Time Frame: three days after surgery
evaluate neutrophil / lymphocyte ratio (NLR) after operation
three days after surgery

three days after surgery
postoperative inflammation function
Time Frame: three days after surgery

three days after surgery
neuropsychological test
Time Frame: Neuropsychological tests were carried out the day before and 5 to 7 days after surgery. The second neuropsychological test time for control subjects was 6 to 9 d
The neuropsychological test battery included the tests used to evaluate patients for delayed neurocognitive recovery in the International Study of Post-Operative Cognitive Dysfunction: (1) word learning: visual verbal learning test based on the Rey's auditory recall of words; (2) word recall: the number or words recalled from visual verbal learning trials after a 20-min delay; (3) cognitive flexibility: including trail making test A and B; (4) distractibility: Stroop color word interference test; and (5) working memory: letter-digit coding. If a patient exhibited delirium at a testing time, neuropsychological evaluation was postponed 3 days.
Neuropsychological tests were carried out the day before and 5 to 7 days after surgery. The second neuropsychological test time for control subjects was 6 to 9 d

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
