What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This study looks at whether machine learning (a type of artificial intelligence) can accurately predict how long spinal anesthesia lasts in people having knee replacement surgery. Researchers will use patient information like age, surgery details, and anesthesia data to train computer models. The goal is to help doctors plan better and improve recovery after surgery.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Who is studied

This study will include adult patients undergoing elective total knee arthroplasty (TKA) under spinal anesthesia at Kocaeli City Hospital Operating Theaters between November 2025 and March 2026. All participants will receive spinal anesthesia using 0.5% hyperbaric bupivacaine, and intraoperative monitoring will be conducted in accordance with institutional anesthesia standards. The study population represents a homogeneous surgical group in which spinal anesthesia is routinely applied, allowing for standardized anesthesia protocols and reliable measurement of anesthesia duration. Eligible patients will be classified as ASA Physical Status I or II and aged 18 years or older.

Inclusion Criteria: 1. Patients scheduled to undergo total knee arthroplasty between November 2025 and March 2026 at the Kocaeli City Hospital Operating Theaters. 2. Patients who have provided written informed consent to participate in the study. 3. Patients whose surgery is planned under spinal anesthesia. 4. Patients for whom complete clinical data can be obtained during the study period. 5. Adults aged 18 years or older, classified as American Society of Anesthesiologist's (ASA) Physical Status I or II. Exclusion Criteria: 1. Patients who were converted to general anesthesia during surgery or initially operated under general anesthesia. 2. Patients who required postoperative intensive care unit (ICU) admission following anesthesia. 3. Patients who developed surgical complications and for whom postoperative mobilization could not be planned. 4. Patients with cognitive impairment preventing them from completing pain assessment scales in the postoperative period. 5. Patients with neuropathic pain, multiple sclerosis, or other neuromotor disorders will be excluded from the study.
