Objectives

Narrative objectives1

To evaluate anesthetic preconditioning effects of desflurane versus propofol on tourniquet induced ischemia-reperfusion injury during anterior cruciate ligament reconstruction,we measured blood CPK-MM and myoglobin released from damaged akeletal muscles.We hypothesized that desflurane can more effectively decrease CPK-MM and myoglobin released from damaged skeletal muscles than propofol.

Assessment

Primary outcomes

Skeletal muscle cell damage quantified by the release of postoperative creatine phosphokinase-MM (CPK-MM) and the areas under the curve of the CPK-MM concentrations over the 24 h (AUC24 h) and the 48h (AUC48 h). Blood samples are taken preoperatively and 6, 12, 24, and 48 h following release of tourniquet.

Key secondary outcomes

Skeletal muscle cell damage quantified by the release of postoperative myoglobin and the areas under the curve of the myoglobin concentrations over the 24 h (AUC24 h) and the 48h (AUC48 h). Blood samples are taken preoperatively and 6, 12, 24, and 48 h following release of tourniquet.

For operative side, cross-sectional areas of quadriceps femoralis muscles were traced and calculated on MRI before operation and postoperative day 9th, at two slices of 5 cm and 10 cm above the upper margin of the patella, respectively. Change ratio of the areas at the same slice before and after operation was examined.The change ratios of patinets managed with desflurane were compared with those of patients managed with propofol at the corresponding slice, respectively.

Interventions/Control_1

In patients assigned to desflurane group, following intravenous bolus injections of midazolam 1mg and remifentanil 20ug, a continuous intravenous infusion of midazolam at 0.05mg/kg/hr was maintained combined with a continuous infusion of remifentanil at 0.0167 ug/kg/min until an intrathecal anesthesia with 0.5% hyperbaric bupivacaine of 2.5 Ml combined with replacement of an epidural catheter was completed. Then the continuous infusion of midazolam was quitted after a bolus 0.5 mg injection. All patients received intravenous injection of atropine 0.3~0.5 mg before induction of general anesthesia. General anesthesia was induced with desflurane after an additional 10ug bolus injection of remifentanil. The continuous infusion of remifentanil was maintained until extubation of an airway device after surgery. A supralaryngeal airway was inserted after another bolus injection of remifentanil 10ug, at an end-tidal desflurane concentration more than 5 %. Eight % of an end-tidal desflurane concentration was achieved before inflation of the tourniquet at a pressure of 250 mmHg. Ventilation was maintained by pressure-control mode with end-tidal CO2 concentration from 30 to 40 mmHg. Inhalational gas-mixture was Air:O2=1:1. Total gas flow was maintained from 2~4 L/min. General anesthesia was maintained with the continuous infusion of remifentanil and 8 % desflurane until deflation of the tourniquet. Before end of the surgery, desflurane concentration was adjusted downwardly.
All patients received a common postoperative multimodal analgesia combined with epidural patient-controlled analgesia (EPCA) and acetoaminophen. Neither adrenocortico steroids nor non-steroidal anti-inflammatory drugs was administered in all patients until the final blood sample was taken at the postoperative day 2nd .

Interventions/Control_2

In patients assigned to propofol group, after an intravenous injection of midazolam 1mg, intravenous target-controlled infusion of propofol set at a target plasma concentration of 0.5ug/ml was maintained combined with a continuous infusion of remifentanil at 0.0167 ug/kg/min following a bolus injection of remifentanil 20ug during the intrathecal anesthesia combined with replacement of an epidural catheter. After an intravenous injection of atropine 0.3~0.5 mg, general anesthesia was induced with propofol reset at a target plasma concentration of 4ug/ml, combined with an additional 10ug bolus injection of remifentanil and the continuous infusion of remifentanil. A supralaryngeal airway was inserted after another 10ug bolus injection of remifentanil, at a propofol simulated plasma concentration of 2.5 ug/ml or more. A simulated propofol plasma concentration of 4.0 ug/ml was achieved before inflation of the tourniquet at a pressure of 250 mmHg. General anesthesia was maintained with target-controlled infusion of propofol set at a target plasma concentration of 4.0 u/ml until deflation of the tourniquet. The continuous infusion of remifentanil was maintained until extubation of an airway device after surgery. Ventilation was maintained by pressure-control mode with end-tidal CO2 30~40 mmHg. Inhalational gas-mixture was Air:O2=1:1. Total gas flow was maintained at 2-4 l/min. After deflation of the tourniquet, the target plasma concentration of propofol was adjusted downwardly.
All patients received a common postoperative multimodal analgesia combined with epidural patient-controlled analgesia (EPCA) and acetoaminophen.

Outcome measures

CPK–MM(x)= CPK–MM(x)–CPK–MM(0)
(0): before induction of anesthesia
(x): x hour after deflation of the tourniquet

A line graph was drown consisting of the vertical axis(&DELTA;CPK–MM:U/L) and the horizontal axis(time after deflation of the tourniquet: hr).Then the area under the line was calculated.The results were indicated as (mean±SD) DES: 12865.4±8770.9(U/L×hr),pro:10434.3±5117.8(U/L×hr) Based on the ROC obtained from the data, AUC was calculated(AUC=0.57).

In the same way as above, AUC for Mb was also calculated (AUC=0.55)
