Detailed Description
Inadequately treated postoperative pain after gynecological surgery may untowardly affect early recovery and also lead to the development of chronic pain. Laparoscopic surgery is associated with diminished postoperative pain but this does not mean that patients subjected to laparoscopic operations are not in need for analgesia intra- and postoperatively. Opioid-based analgesia is associated with side-effects, such as respiratory depression, postoperative nausea and vomiting and occasional induction of tolerance and hyperalgesia. Therefore, in recent years research has focused on the quest for non-opioid-based regimens for perioperative analgesia in the context of multimodal analgesic techniques. These techniques have been shown to possess significant advantages, such as allowing earlier mobilization after surgery, early resumption of enteral feeding and reduced hospital length of stay.
In this context, the intraoperative intravenous injection of lidocaine has been reported to improve postoperative pain control, reduce opioid consumption and improve the quality of postoperative functional recovery after general anesthesia. Intraoperative infusions of ketamine (an N-methyl-D-aspartate receptor inhibitor) have also been correlated with reduced pain scores and a decrease in analgesic requirements postoperatively. Lastly, dexmedetomidine is a highly selective alfa-2 adreno-ceptor agonist that provides sedation, analgesia, and sympatholysis. Its perioperative intravenous administration has been associated with a reduction in postoperative pain intensity, analgesic consumption and nausea.
There is insufficient data in literature investigating the effect of combinations of these agents intraoperatively. It would be of interest to demonstrate whether the administration of combinations can be used towards the achievement of a completely opioid-free anesthetic regimen. Additionally, it can be hypothesized that the combination of non-opioid drugs with different targets can lead to enhanced postoperative recovery, an improved opioid-sparing effect and a decrease in the development of chronic pain as compared to the administration of opioids.
Therefore, the aim of this study will be to investigate the effect of a combination of intravenous infusions of lidocaine-ketamine-dexmedetomidine versus fentanyl on recovery profile, quality of recovery and postoperative pain after elective laparoscopic gynecological surgery.

Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Active Comparator: ketamine-lidocaine-dexmedetomidine (KLD) group combination of ketamine-lidocaine-dexmedetomidine in one syringe |
Drug: ketamine-lidocaine-dexmedetomidine
In the KLD group, patients will be administered 0,25 mcg/kg Dexmedetomidine in 100 mL of normal saline within 10 minutes. Followingly, they will receive 1mL/10 kg of the solution containing ketamine, lidocaine and dexmedetomidine at predefined concentrations. As maintenance, they will be receiving 1mL/10kg/h of the aforementioned solution.

Outcome Measures
Primary Outcome Measures
- change from baseline in Quality of Recovery (QoR)-15 score after surgery [24 hours postoperatively]
The QoR-15 is a quality of recovery scale that consists of 15 questions (items),including questions regarding pain (2 items), physical comfort (5 items), self-care ability (2 items), psychological support (2 items) and emotional state (4 items). Every item is scored on a scale of 10, with the lowest total score of 0 and the highest score of 150. The higher the score, the better the recovery quality of the patient
- pain score on arrival to Post-Anesthesia Care Unit (PACU) [immediately postoperatively]
pain score by the use of Numeric Rating Scale (NRS) on arrival to PACU, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score at discharge from Post-Anesthesia Care Unit (PACU) [at discharge from Post Anesthesia Care Unit (PACU), approximately 1 hour postoperatively]
pain score by the use of Numeric Rating Scale (NRS) at discharge from PACU, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 3 hours postoperatively [3 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 3 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 6 hours postoperatively [6 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 6 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
- pain score 24 hours postoperatively [24 hours postoperatively]
pain score by the use of Numeric Rating Scale (NRS) 24 hours postoperatively, ranging from 0 to 10, where 0 means "no pain" and 10 means "worst pain imaginable"
Secondary Outcome Measures
- Post Anesthesia Care Unit (PACU) duration of stay [immediately postoperatively]
duration of patient stay at PACU
- sedation on arrival to Post-Anesthesia Care Unit [immediately postoperatively]
sedation will be assessed with a 5-point sedation scale, where: 1, patient perfectly conscious; 2, patient feels a little drowsy; 3, patient seems to be sleeping but immediately reacts to verbal stimulation; 4, patient seems to be sleeping but slowly reacts to verbal stimulation and 5, patient seems to be sleeping and does not react to verbal stimulation but does react to a stimulus such as shaking or pain
- sedation at discharge from Post-Anesthesia Care (PACU) Unit [at discharge from Post Anesthesia Care Unit (PACU), approximately 1 hour postoperatively]
sedation will be assessed with a 5-point sedation scale, where: 1, patient perfectly conscious; 2, patient feels a little drowsy; 3, patient seems to be sleeping but immediately reacts to verbal stimulation; 4, patient seems to be sleeping but slowly reacts to verbal stimulation and 5, patient seems to be sleeping and does not react to verbal stimulation but does react to a stimulus such as shaking or pain
- sevoflurane consumption during general anesthesia [change of sevoflurane vaporizer weight from before induction to end of anesthesia, an average period of 2-3 hours]
the sevoflurane vaporizer will be weighed before anesthetic induction and at the end of anesthesia and consequently sevoflurane consumption during anesthesia will be determined
