Brief Summary
The investigators plan to evaluate the analgesic effect of systemic Lidocaine in addition to general anesthesia during bariatric surgery. Patients will be subdivided into a "Lidocaine group" and a "Control group". The primary outcome will be the proportion of patients suffering from higher pain intensity within the first four hours after bariatric surgery. Secondary outcomes include the average maximal pain intensity during first four hours and during 48 hours, total opiate consumption, occurence of postoperative nausea and vomiting, time to first defecation and total time spent in hospital.

Outcome Measures
Primary Outcomes (1)
Postoperative VAS/NRS Score
Any development of VAS/NRS score \> 3 (Visual Analog Scale/Numeric Rating Scale ranging from minimum 0 to maximum 10 points, with 0 points as "no pain" to 10 points as "severe pain") , in hourly measurements within the first four hours after completion of bariatric surgery to evaluate the pain experienced by patients after the surgical intervention
0 - 4 hours after surgery
Secondary Outcomes (5)
Average experienced maximal pain during the first four hours and 48 hours after Surgery
0 - 48 hours after surgery
Occurence of Postoperative Nausea and Vomiting after Surgery
0 - 48 hours after surgery
Time to first Defecation
0 - 48 hours after surgery
Duration of Hospitalization
0 - 48 hours after surgery
Total Amount of Opiate Consumption
0 - 48 hours after surgery
Study Arms (2)
Lidocaine Hydrochloride
EXPERIMENTAL* 1.5 mg/kg lean body mass lidocaine (lidocaine 1%) bolus I.V. as general anesthesia steady state concentration is accomplished * 1.5 mg/kg lean body mass/h lidocaine I.V. with beginning of surgical procedures * after completion of surgery: transfer to PACU, pain evaluation for 48 hours * duration of intervention: lidocaine infusion up to four hours from completion of surgery, or till transfer to surgical ward
Saline Solution
PLACEBO COMPARATOR* 0.15 ml/kg lean body mass saline 0.9% bolus I.V. as general anesthesia steady state concentration is accomplished * 0.15 ml/kg lean body mass/h saline 0.9% I.V. with beginning of surgical procedure * after completion of surgery: transfer to PACU, pain evaluation for 48 hours * duration of intervention: saline infusion up to four hours from completion of surgery, or till transfer to surgical ward
Interventions
The intervention to be studied will be the additional application of systemic lidocaine 1% dosed 1.5 ml/kg LBM to general anesthesia in bariatric surgery. Patients, randomly assigned to one study group, will be surveyed for 48 hours after completion of surgery, experienced pain, occurrence of PONV, time to first defecation and length of hospitalization will be monitored. Patients, medical practitioner, nurses and investigators will be blinded by utilization of equal appearance and packing of IMPs, which will be fabricated individually for each patient and on request one to two days before surgery by the pharmacy. Each patient will self-evaluate his maximal experienced pain eight-hourly during a sequence of 48 hours after completion of surgery.
The intervention to be studied will be the additional application of NaCl 0.9% dosed 1.5 ml/kg LBM to general anesthesia in bariatric surgery as a placebo. Patients, randomly assigned to one study group, will be surveyed for 48 hours after completion of surgery, experienced pain, occurrence of PONV, time to first defecation and length of hospitalization will be monitored. Each patient will self-evaluate his maximal experienced pain eight-hourly during a sequence of 48 hours after completion of surgery.
