Brief Summary:
the aim is to compare the effects of two different doses of intraarticular ketamine on postoperative pain scores and analgesic knee artroscopy

Condition or disease Intervention/treatment Phase
Arthroscopy Drug: Ketamine 0.5 Drug: Ketamine 1 Drug: % 0.9 NaCl Phase 4

Detailed Description:

All pateints are going to be operated under general anesthesia. At the end of the study patients are going to be randomyl seperated into 3 groups. The surgeon is going the following drugs intraarticulary.

Group KL1: 0.5 mg/kg ketamin in % 0..9 NaCl at a total volume of 20 ml Group KL2: 1 mg/kg ketamin in % 0.9 NaCl at a total volume of 20 ml Group SL: 20 ml % 0.9 NaCl ll patients are going to receive a periarticula injection of 10 ml 0.5 bupivacaine and patient controlled analgesia with morphine.

VAS scores and total analgesic requirement is going to be evaluated.

ketamin 0.5 mg/kg intraarticular
Drug: Ketamine 0.5
İntrarticular Ketamine 0.5 mg/kg + 0.9 Nacl Total Volume 20 ml
Other Name: Group 1

Active Comparator: Ketamine 1 mg/kg
ketamin 1 mg/kg intraarticular injection
Drug: Ketamine 1
İntrarticular Ketamine 1 mg/kg + 0.9 NaCl Total Volume 20 ml
Other Name: Group 2

Sham Comparator: % 0.9 Saline
% 0.9 NaCL intraarticular injection
Drug: % 0.9 NaCl
Intraarticular %0.9 NaCl
Other Name: Group 3

Primary Outcome Measures :
  1. Change in postoperative pain scores throughout time evaluated by VAS [ Time Frame: VAS scores at rest and during activity will be evaluated for 24 hours. The first measurement will be recorded immediately after surgery and at 30 minutes interval for the first hour. Afterwards at postoperatively. ]
    Pain scores are going to be evaluated by VAS scores at rest and VAS scores at activity

  2. Difference in opioid Sparing effect measured through morphine amount delivered by a patient controlled analgesia device. [ Time Frame: Total amount off delivered morphine will be recorded for 24 hours. ]
    The total amount of morphine delivered by the patient controlled analgesia device in the first 24 hours will be recorded.

Secondary Outcome Measures :
  1. Time for discharge measured by eligible for discharge criteria [ Time Frame: Discharge criterias will be evaluated every three hours until postoperative 24. hour. In patients who did not complete the discharge criteria in the postoperative 24 hours period, they will be defined as prolonged discharge. ]
    The time needed to fullfill the dicharge criteria (stable vital signs, able to walk, able to eat, nausea and vomit free, able to mixture)
