Descrição detalhada
Intrahepatic cholestasis of pregnancy (ICP) is an important obstetric complication that occurs in the middle and late stages of pregnancy, characterized mainly by pruritus and elevated serum total bile acid (TBA) levels.
Pruritus usually begins on the palms and soles of the feet and can gradually spread. It typically shows a 'lighter during the day and heavier at night' pattern, severely affecting the patient's quality of life. It can also lead to physical and psychological disorders, and even cause mental abnormalities and self-harming behaviors in patients.
Esketamine is the right-handed isomer of ketamine and is a non-competitive N-methyl-D-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 important role in the transmission of non-histaminergic itching. Eslicarbazepine acetate, as a highly selective NMDA receptor antagonist, may alleviate the transmission and propagation of itching. However, there are no reports on whether a single intravenous injection of esketamine can alleviate the pruritus symptoms of patients with pregnancy-induced intrahepatic cholestasis. This experiment aims to investigate the effect of a single intravenous injection of esketamine during cesarean section on postoperative pruritus in patients with pregnancy-induced intrahepatic cholestasis.

NRS pruritus score at 24 hours after surgery
Prazo: 24 hours after the surgery
|
The patient evaluated the intensity of pruritus with 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.

5-D itch scale at 72 hours after surgery
Prazo: 72 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 NRS pruritus score was completed by the patient 24 hours after the operation.
The investigators recorded this score as a statistical indicator.

Pain Score (NRS)
Prazo: 6 hours, 12 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.
|
6 hours, 12 hours, 24 hours, 48 hours, 72 hours after the surgery

The incidence of postoperative sleep disturbance on the first、second and third postoperative nights
Prazo: the first、second and third nights after surgery
|
The patient completed the Sleep Quality Scale (AIS,Athens Insomnia Scale) one day before the surgery.
There are a total of 8 items in the AIS, 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 AIS scores as statistical indicators.

The patient completed the Self-Rating Anxiety Scale (SAS, Self-Rating Anxiety Scale) one day before the surgery.
The SAS consists of 20 items.
Among them, 15 items are positive ratings (such as "I feel more nervous and anxious than usual"), and 5 items are negative ratings (such as "I feel everything is fine", which are the reverse items numbered 5, 9, 13, 17, and 19).
The content covers subjective feelings of anxiety and various physical symptoms.
The investigators asked the patient to fill out this questionnaire again 72 hours after the surgery to assess the changes in anxiety.

The EPDS consists of 10 items, covering aspects such as mood, anxiety, and self-blame.
Scores range from 0 to 9: within the normal range, no special intervention is required; 10-12: borderline range, suggesting a need for follow-up observation; 13-30: screening positive, indicating possible postpartum depression, and further assessment is necessary.
The investigators asked the patient to fill out this questionnaire again at the seventy-second hour after the surgery to assess the changes in depression.
