Description of intervention(s) / exposure
Patients without or with type 2 diabetes diagnosed with chronic cholecystitis and scheduled for elective open cholecystectomy will be studied.
All patients will receive a general anaesthetic and maintained with sevoflurane 1.5% and fentanyl 5 µg/kg. Patients also receive diclofenac 75 mg i.v. once before the surgical incision.
Haemodynamic variables were defined as: hypotension (MAP < 60 mmHg), hypertension (MAP > 100 mmHg), bradycardia (heart rate < 40 beats/min) and tachycardia (heart rate > 90 beats/min).
After completion of the surgical procedure (final suture) and emergence from anaesthesia, all patients will be transferred to the recovery room.
Duration of surgery was defined as the time from skin incision to completion of skin suturing. Onset of postoperative pain was defined as the time from end of anaesthesia until presence of any postoperative pain score. Pain management will be immediately after assessment according to institutional standards.
Postoperative pain will be evaluated by using a 0–10 numerical rating scale (NRS) (0 = no pain and 10 = worst pain imaginable), and onset of postoperative pain will be defined as the time from end of anaesthesia until presence of any postoperative pain score. Each
participants will be observed for at least 8 hours post-surgery,

Outcomes
Primary outcome [1] 299082 0
Primary outcome 1: Pain score at onset of postoperative pain assessed by using a 0–10 numerical rating scale (NRS).
Timepoint [1] 299082 0
The intensity of the pain will be evaluated and will be recorded when the patient is already in the recovery room and shows any pain score. The evaluation will be for a maximum of 8 hours.
Secondary outcome [1] 326089 0
Time of onset of postoperative pain. This outcome will be evaluated as reported by the patient and will be recorded in the data collection sheet by a researcher blinded to the study.
Timepoint [1] 326089 0
Time from end of anaesthesia until presence of any postoperative pain score
Secondary outcome [2] 343536 0
Duration of surgery. This outcome will be evaluated through nursing records and the study data sheet.
Timepoint [2] 343536 0
It will be the time elapsed from the moment of the incision of the skin until completing the suture of the skin. According to the experience of the surgeons and the literature data will be about 1 hour.

Statistical methods / analysis
Age, height, weight, BMI, glucose concentration, duration of surgery, time to onset postoperative pain and NRS values will be recorded. Analysis will be done by mean comparison with the Student´s t-test. Nominal data (sex, ASA, pain intensity) between the two groups will be compared by the Chi-square test or Fisher´s exact test. All data will be presented as means ± S.E.M. or number and percentages. A p value < 0.05 will be considered statistically significant.
