ESPB With Dexmetomidine May Provide Analgesia

Analgesic Efficacy of adding different doses of dexmedetomidine as adjuvants with bupivacaine vs. bupivacaine only in ultrasound-guided erector spinae plane block in morbidly obese patients undergoing Laparoscopic Bariatric surgery. A RANDOMIZED CONTROLLED DOUBLE BLINDED STUDY.

Bariatric surgery is recognized as an essential and effective treatment for obesity and relevant metabolic diseases, such as type 2 diabetes . With the promotion of enhanced recovery after surgery (ERAS) in bariatric surgery, the administration of the ERAS protocol has been widely accepted . Compared with traditional treatment, ERAS reduces the potential opportunity for postoperative complications, ultimately improving the quality of care for patients . Inadequate postoperative pain management for patients may increase the amount of opioid analgesic drugs consumed, prolong time to off-bed activity and hospitalization, augment the incidence of relevant complications, increase medical costs, and reduce the quality of life Laparoscopic bariatric surgeries are considered minimally invasive procedures, but they can cause severe pain . Opioids are excellent analgesics, but they have many side effects as respiratory depression, which may further complicate pain management in bariatric surgeries, particularly in cases with obstructive sleep apnea . Other comorbidities such as diabetes mellitus and cardiovascular diseases that are common in patients with obesity can also lead to difficulties with pain management . This complexity highlights the challenges of the optimal choice of analgesia in bariatric surgery. The new regional blocking technique (Erector spinae plane block) can utilize to reduce postoperative pain effectively in various surgical procedures such as breast, thoracic, abdominal and lumbar surgery . However, although usually the use of long-acting local anesthetics (LAs), not provide long duration of action . Even though continuous catheter-based nerve block can prolong the postoperative pain relief time, this technique requires additional time and cost, and increases the risk of infection and neurological complications Dexmedetomidine (DEX) is a highly selective alpha-2 adrenergic receptor agonist with sedative and analgesic sparing effects, reduced delirium and agitation, with additive perioperative sympatholysis, cardiovascular stabilizing effects, and preservation of respiratory function.. In previous clinical studies, DEX as adjuvant to LAs as the potential to prolong blockade duration. However, it remains unclear whether Dex as an adjunct for bupivicaine to ESPB can significantly improve the quality of postoperative analgesia and recovery after Laproscopic bariatric surgery in morbidly obese patients. Thus, the main objective of the present study was to explore the effects of different dosages of Dex as an adjunct for bupivicaine combined with ESPB on the quality of postoperative analgesia and recovery and achieve opioid free anasthesia in patients following laproscopic bariatric surgery
