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,

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.

Summary
Brief summary
Pre-clinical studies have shown that experimental diabetes induces hyperalgesia in rodents. Additionally, diabetic patients report more postoperative pain after lumbar spine surgery or total abdominal hysterectomy than non-diabetic patients. Interestingly, some studies indicate that cholelithiasis is three times more frequent in diabetic than in non-diabetics patients. However, the comparison of postoperative pain after cholecystectomy between diabetic and non-diabetic patients remains unknown. Thus, the primary aim was evaluate the intensity of postoperative acute pain in diabetic patients undergoing open cholecystectomy.

Public notes
The study does not need to be evaluated by the research ethics committee, since it is not a new postoperative pain treatment. Patients will be treated with the conventional and institutional scheme already defined for the treatment of postoperative pain after open cholecystectomy. The study is observational, therefore only the intensity of pain in diabetic and non-diabetic patients will be recorded from their arrival in the recovery room until 8 hours later. If any of the patients manifest values of 3 or more on the NRS scale (moderate to severe) during the planned observation period, an analgesic rescue will be given and the pain and time scores will be recorded. The patient who had the above characteristics will no longer be observed.
