Overview
Brief Summary
The incidence of breast cancer is among women world wide, detection increased with introduction of mammography as a screening tool. surgical resection of breast cancer contributes to the generation of acute and chronic post mastectomy pain. This study aims at comparing the effect of erector spinae block versus serratus block versus intravenous morphine in patients undergoing modified radical mastectomy for breast cancer surgeries regarding pain control and possible side effects
Detailed Description
One of the most common types of cancer affecting women is breast cancer. Surgical resection is one of the main approaches applied for solid tumors. surgical approach for breast cancer involve the breast region. Various analgesic modalities are used for proper perioperative pain control. Morphine has always been considered as the gold standard analgesic, however opioids have multiple side effects. Several loco-regional techniques have been introduced for breast surgery pain management including serratus plane block (SPB) and erector spinae plane (ESP) block. In this study the investigators are comparing the effect of erector spinae block versus serratus block versus intravenous morphine in patients undergoing modified radical mastectomy for breast cancer surgeries regarding intraoperative and postoperative analgesia, time to first analgesic, any possible side effects

Arms & Interventions
erector spinae block
Ultrasound guided erector spinae block with will be done after induction of intravenous anesthesia. After identification of trapezius, rhomboid major, and erector spinae muscles. The needle will be inserted in a cephalad-to-caudal direction until the tip contact transverse process and the needle tip is visualized in the plane deep to the erector spinae muscle. The needle tip position is confirmed by visualizing linear spread of test dose between the muscles after injection. A total dose of 25 mL of 0.25% bupivacaine will be injected.
Intervention: erector spinae block
serratus anterior block
Ultrasound guided serratus anterior block will be done after induction of intravenous anesthesia. The serratus anterior, latissimus dorsi, and the intercostal muscles will be identified in the fourth and fifth intercostal level, an 18 G Tuohy needle will be advanced in the plane between the serratus anterior muscle and the intercostal muscles. A total dose of bupivacaine 25ml in a concentration of 0.25% will be administered under the serratus muscle after a test dose using an in-plane technique.
Intervention: serratus plane block
intravenous morphine
intravenous morphine will be administrated in a dose of 0.1 mg per kg after induction of general anesthesia
Intervention: Morphine Sulfate
