Gedetailleerde beschrijving

Pruritus (itching) is one of the most common clinical conditions in the elderly population. Its etiology is complex, and the prevalence gradually increases with age. Pruritus in the elderly not only imposes a significant disease burden but also severely affects their sleep quality and daily life. This chronic, persistent itching often disrupts the skin barrier function, easily creating a vicious itch-scratch cycle, which leads to multiple damages to the patient's quality of life.Esketamine is the right-handed isomer of ketamine and is a non-competitive N-methyHD-aspartate (NMDA) receptor antagonist. It has the effects of rapid pain relief,rapid antidepressant action, sedation, and improvement of sleep. Relevant studies have shown that the NMDA receptor may play an importantrole in the transmission of non-histaminergic itching. However, there is still a lack of reports on whether it can relieve pruritus symptoms in elderly patients. This experiment intends to investigate the effect of intraoperative esketamine infusion on skin pruritus in elderly surgical patients.

Primaire uitkomstmaten

Uitkomstmaat
Maatregel Beschrijving
Tijdsspanne
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.
24 hours after surgery

Tijdsspanne
5D-IS score at 48 hours,72 hours and the seventh day after surgery
Tijdsspanne: 48 hours,72 hours and the seventh day 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.
48 hours,72 hours and the seventh day after surgery
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.
24 hours after surgery
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.

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.

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.
