Patient Satisfaction and Postoperative Outcomes Following All-on-Four Implant Surgery Under Analgosedation

The primary outcome measures included patient-reported postoperative pain and swelling, analgesic use and systemic inflammatory response.

Postoperative pain intensity and swelling were assessed using a 10-point Visual Analogue Scale (VAS), where 0 indicated the absence of symptoms and 10 indicated the maximum perceived severity. Assessments were performed preoperatively and at 2, 6, 12, 24, 48, and 72 hours postoperatively.

Rescue analgesic consumption was recorded for each patient during the first three postoperative days and quantified based on the total number of tablets consumed and daily dose. Analgesic intake was used as an indirect indicator of postoperative discomfort.

To evaluate the systemic inflammatory response, serum C-reactive protein (CRP) levels were measured preoperatively and on postoperative day 3 using standard laboratory procedures.

All patients were asked to complete a structured questionnaire assessing their experience with anesthetic management. The questionnaire collected demographic data and medical history, and included items related to previous exposure to analgosedation, attitudes toward different anesthesia modalities, perioperative anxiety, adequacy of preoperative information, patient involvement in anesthesia decision-making, and overall satisfaction with the anesthetic care. In addition, patients were asked to report intraoperative and early postoperative discomfort, adverse sensations following emergence from analgosedation, and their willingness to undergo the same anesthesia protocol in the future
