Patients Undergoing Modified Radical Mastectomy

Brief summary

Modified radical mastectomy (MRM) is one of the most common surgeries performed, and one that may be associated with significant acute postoperative pain in breast surgery. Acute postoperative pain is an independent risk factor in the development of chronic post-mastectomy pain . Various regional anesthetic procedures have been tried to provide better acute pain control and, consequently, less chronic pain. They can reduce perioperative opiates requirement and thereby decreasing their possible side effects. These regional procedures include local wound infiltration, lumbar intrathecal fentanyl injection, thoracic epidural, thoracic paravertebral block (PVB), and ultrasound (US)-guided interfascial plane blocks. Currently, Ultrasound (US)-guided interfascial plane blocks have been recommended as safe, easy, and reliable alternatives to the use of thoracic epidural and paravertebral blocks in providing analgesia for patients about to undergo breast surgery. Serratus anterior plane block (SAPB) is one of the Ultrasound (US)-guided interfascial plane blocks, it blocks the intercostal nerves II-VI by injection above or below the serratus muscle in the mid-axillary line and spares the pectoral nerves. We assumed that SAPB could safely provide a better analgesic profile with an opioid-sparing effect than Intrathecal fentanyl. We will perform this study to evaluate this assumption.

Interventions

PROCEDURESerratus Anterior Plane Block

SAPB will be done preoperative before induction of anesthesia under songraphic guidance and aseptic conditions with the patient in the lateral position, with the side of the surgical side up and the upper limb hanging over the patient's head. The ribs will be then counted, and when the 5th rib is identified, the high-frequency probe will be put over it, in the mid-axillary line in a sagittal plane. The ribs, pleura, overlying serratus muscle and latissimus dorsi muscle will be identified, and the needle will be advanced cephalic in-plane until the tip reaches the plane between the serratus anterior and latissimus dorsi. Afterward, 2 mL dextrose 5% will be injected; then, 30 mL of bupivacaine 0.25% will be injected in the plane between the serratus anterior and latissimus dorsi.

PROCEDURELumbar Intrathecal Fentanyl Injection

Patients will receive 25 microgram intracthecal fentanyl immediately preoperative.

Design outcomes

Primary

MeasureTime frameDescription
analgesic effect of serratus anterior plane block and lumbar intrathecal fentanyl injection after modified radical mastectomy1 yearcompare the analgesic effect between serratus anterior plane block and lumbar intrathecal fentanyl injection by using visual analogue score (vas). -Postoperative pain will be assessed using visual analog score (VAS) \[0-10\]. 0 - 3 mild pain 4 - 6 moderate pain 7 - 10 severe pain 10 \<unbearable pain)

Secondary

MeasureTime frameDescription
Hemodynamics effects of serratus anterior plane block and lumbar intrathecal fentanyl injection in patient undergoing modified radical mastectomy1 yearcompare between serratus anterior plane block and lumbar intrathecal fentanyl injection as regard, hemodynamics of patient undergoing modified radical mastectomy. -The heart rate (HR), noninvasive arterial systolic blood pressure (SBP), diastolic blood pressure (DBP) and peripheral oxygen saturation (SpO2) will be recorded at baseline, after induction and with skin incision and every 5 minutes intraoperative till the end of surgery. And postoperative at 30 min, 1, 2, 3, 6, 12 and 24 hours.
Intra venous analgesics consumption after serratus anterior plane block and lumbar intrathecal fentanyl injection in patient undergoing modified radical mastectomyone yearcompare between serratus anterior plane block and lumbar intrathecal fentanyl injection in patient undergoing modified radical mastectomy as regard intra venous analgesics consumption. All patients will receive paracetamol (15mg/KG/dose) immediately postoperative and after 6 hours. Patients will be assessed every one hour in the first 6 hours then every 3 hours in the next 18 hours. Patients will receive ketorolac 30 mg if VAS 3-5 . If VAS\>5 ,morphine 0.1mg/kg will be given then total ketorolac and morphine consumption in 24 hours will be calculated and compared between both groups .
