1-spinal anaesthesia with hyperbaric bupivacaine 0.5% (15-20 mg)
2- Diclofenac potassium 75 mg |

after hemodynamic monitoring,An 18- gauge intravenous cannula will be inserted into the patient's forearm and 500 mills of intravenous fluid (ringer acetate) will be administrated. premedications will not be given. All patients in both groups will be given spinal anaesthesia by 25 G needle with hyperbaric bupivacaine 0.5% (15-20 mg) according to the patient’s height, in the L 4- L 5 intervertebral space. During spinal injection, no supplementary opioids will be given; the level of anaesthesia will be assessed by pin-prick every five minutes in the first 20 minutes till it reached T4-T6 level which considered sufficient to start surgery.When the reported VAS score is 3 or more, a loading dose of 5 mg morphine will be administered via slow i.v route. Then, a PCA will be administered. The PCA pump will be loaded with 1mg / ml of morphine and set to deliver on demand doses of 2 ml with 5 minutes lockout intervals. Background infusion will not be allowed. At the End of operation Diclofenac potassium 75 mg will be administered to all patients by intramuscular injection. |

after hemodynamic monitoring,An 18- gauge intravenous cannula will be inserted into the patient's forearm and 500 mills of intravenous fluid (ringer acetate) will be administrated. premedications will not be given. All patients in both groups will be given spinal anaesthesia by 25 G needle with hyperbaric bupivacaine 0.5% (15-20 mg) according to the patient’s height, in the L 4- L 5 intervertebral space. During spinal injection, no supplementary opioids will be given; the level of anaesthesia will be assessed by pin-prick every five minutes in the first 20 minutes till it reached T4-T6 level which considered sufficient to start surgery.. Electric ear acupuncture will be done by fine needles (10mm x 30guage) to the anatomically defined 4 points of ear acupuncture which are called ; Shen Men Point (Divine Gate Point ) or point 55 which is a sedative analgesic anti-inflammatory point, thalamus Point - 26 which is an analgesic point in acute and chronic severe pain , Analgesia Point 3, and Uterus Point __ 58.Then four pre-sterilized single use acupuncture needles will inserted in the predetermined acupoints and connected to clamps of electrode cords that are connected to electro-acupuncture therapeutic apparatus (KWD-808I MULTIPURPOSE HEALTH DEVICE, ChangzhouYingdi Electronic Medical Device Co., China.The electro-acupuncture device will be switched on and adjusted according to instruction manual for use to provide continuous wave with a frequency of 2Hz and output impulse amplitude of 6-10 volts according to patient's ability. At the end of surgery, the electro-acupuncture device will be switched off and the fine needles will be replaced by press needles in the same acupoints to be removed after 24 hours. When the reported VAS score is 3 or more, a loading dose of 5 mg morphine will be administered via slow i.v route. Then, a PCA will be administered. The PCA pump will be loaded with 1mg / ml of morphine and set to deliver on demand doses of 2 ml with 5 minutes lockout intervals. Background infusion will not be allowed At the End of operation . Diclofenac potassium 75 mg will be administered to all patients by intramuscular injection. |
