The Effect Of Ultrasound-guided Modified Pectoral Nerves Block Versus Ketamine Plus Magnesium Infusion On Analgesic Profile In Breast Cancer Surgeries

2019-09-24 05:27:26 | BioPortfolio


Background: Postoperative pain is one of the greatest patient concerns following surgery. However, general anesthesia cannot provide adequate postoperative pain control and the routine use of parenteral opioids aggravates postoperative sedation, nausea, emesis, impaired oxygenation and depressed ventilation.


The investigators assume that both ultrasound guided Modified Pecs Block and combination of Ketamine and Magnesium sulphate infusion can achieve better analgesia in major breast cancer surgery in the form of reducing total amount of intraoperative fentanyl requirement and reducing postoperative morphine requirement and improvement of postoperative VAS scores both at rest and during shoulder movement so we plan this study to evaluate this assumption


Surgery on the chest wall is relatively common and can be associated with significant postoperative discomfort and pain; and one of the most common surgical sites on the chest wall is the breast, with the main indication for breast surgery being breast cancer. Breast cancer has continued to be the most common cancer in females, accounting for approximately 31% of all newly detected cancer cases in the female population, worldwide. (1, 2) Thousands of patients undergo surgery in the mammary and axillary regions every year, and these procedures tend to cause significant acute pain and may develop in to cases of chronic pain in 25-60% of cases. (3) Pain can be controlled using systemic opioids which have a respiratory depressant effect and causing nausea and vomiting.

Also can be controlled using epidural catheter that can cause haemodynamic instability, so we are searching about how to devrease pain with less complications.

Medical and Biotech [MESH] Definitions

A cyclohexanone derivative used for induction of anesthesia. Its mechanism of action is not well understood, but ketamine can block NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE) and may interact with sigma receptors.

A hallucinogen formerly used as a veterinary anesthetic, and briefly as a general anesthetic for humans. Phencyclidine is similar to KETAMINE in structure and in many of its effects. Like ketamine, it can produce a dissociative state. It exerts its pharmacological action through inhibition of NMDA receptors (RECEPTORS, N-METHYL-D-ASPARTATE). As a drug of abuse, it is known as PCP and Angel Dust.

Magnesium chloride. An inorganic compound consisting of one magnesium and two chloride ions. The compound is used in medicine as a source of magnesium ions, which are essential for many cellular activities. It has also been used as a cathartic and in alloys.

A group of enzymes that catalyzes the transfer of a phosphate group onto a nitrogenous group acceptor. EC 2.7.3.

The informal or formal organization of a group of people based on a network of personal relationships which is influenced by the size and composition, etc., of the group.
