5D-IS score at 24 hours after surgery
Tijdsspanne: 24 hours after surgery
|
The duration, severity, outcome trend, life impairment and pruritus site (5-D) were used to evaluate the patient's pruritus.Each dimension was scored from 1 to 5, with a total score ranging from 5 to 25.
The higher the score, the more severe the itching.

The incidence of pruritus on the 24 hours after surgery
Tijdsspanne: 24 hours after surgery
|
The 5D-IS score was completed by the patient 24 hours after the operation.
The investigators recorded this score as a statistical indicator.

|
NRS pruritus score at 24 hours,48 hours and 72 hours after surgery
Tijdsspanne: 24 hours,48 hours and 72 hours after surgery
|
The patient evaluated the intensiy of prurtus wth 11 numbers ranging from 0 to 10,and the higher the number, the more severe the condition.
The higher the number, the more severe the itching.
0: No sensation.
1-3: Mild itching.
4-6 Moderate itching 7-9: Severe itching.
10; Extrermely severe itching.

Pain Score (NRS)
Tijdsspanne: 1 hours, 24 hours, 48 hours, 72 hours after the surgery
|
The pain score at rest or after movement was evaluated by pain 11-point numerical rating scale (NRS): 0= no pain, 10 = greatest imaginable pain.
|
1 hours, 24 hours, 48 hours, 72 hours after the surgery
|
|
The incidence of postoperative sleep disturbance on the first. second and third postoperative nights
Tijdsspanne: the first,second and third nights after surgery
|
The patient completed the Sleep Quality Scale (AlS, Athens Insomnia Scale) one day before the surgery, There are a totat of 8 items in the AlS,with the score ranging from 0 to 24.
A total score of 6 or above indicates a diagnosis of insomnia.
We asked the patients to fill out this questionnaire after the first,second and third postoperative nights to evaluate the changes in sleep quality.
The investigators recorded AlS scores as statistical indicators.

Montreal Cognitive Assessment (MoCA)
Tijdsspanne: 24 hours, 48 hours, 72 hours after the surgery
|
The Montreal Cognitive Assessment consists of 7 items, which evaluate visuospatial and executive function (5 points), naming (3 points), attention (6 points), language (3 points), abstract thinking (2 points), delayed recall (5 points), and orientation (6 points) respectively.
A total score of ≥26 points indicates basically normal cognitive function; a total score of <25 points suggests cognitive decline.

24 hours, 48 hours, 72 hours after the surgery
|
|
Confusion Assessment Method (CAM)
Tijdsspanne: 24 hours, 48 hours, 72 hours after the surgery
|
Confusion Assessment Method CAM is assessed based on four core features.
Feature 1: Acute onset or fluctuating course; Feature 2: Inattention; Feature 3: Disorganized thinking; Feature 4: Altered level of consciousness.
The diagnosis of delirium requires a positive result for Feature 1 + a positive result for Feature 2 + a positive result for either Feature 3 or Feature 4.
