Filter by:Acute postoperative pain is defined as sudden onset pain that develops after stimulation due to surgical intervention. It is most severe in the first 24 hours after surgery and gradually decreases in severity and creates dissatisfaction in the patient. Postoperative pain that cannot be treated properly can cause various systemic effects, prolongation of hospital stay, decrease in patients' quality of life, and development of chronic pain. An increase in blood pressure, heart rate, cardiac irritability and systemic vascular resistance is observed with the sympathetic response due to pain. Increased myocardial workload and oxygen consumption may increase or trigger myocardial ischemia. Pulmonary dysfunction has an important place in the determination of mortality and morbidity after surgery and anesthesia.Especially in patients who have undergone thoracic surgery, pain limits the movements of the thoracic muscles, reducing functional residual capacity and vital capacity.This causes the development of atelectasis in the patient and the development of hypoxia and pneumonia due to the deterioration of the ventilation/perfusion ratio. Effective analgesia can be achieved in the postoperative period by administering a certain volume of local anesthetic between any two muscle planes using USG. In SAPB, a local anesthetic is injected between the serratus anterior muscle and the latissimus dorsi muscle to create sensory paresthesia in the thoracic wall. It is known to reduce pain scores in the postoperative period. Serratus anterior plane block is a safe facial plane block performed under USG guidance.Depending on the application site of the block and the amount of local anesthetic administered, different numbers of intercostal nerves, long thoracic nerves and thoracodorsal nerves may be affected. The fact that Serratus anterior plane block (SAPB) is effective between T2-T9 dermatomes enables it to be used effectively in lateral thoracic wall surgeries.
Dexmedetomidine is an α2 receptor agonist with sedative and analgesic properties. In previous reports, dexmedetomidine improves smoothness of postoperative recovery and reduces intraoperatory imflammatory responses. As patients receiving breast surgeries are especially vulnerable to postoperative nausea/ vomiting, the dosage of narcotics and associated complications were concerned for not only comfortness but also postoperative oral intake and discharge. The invetigators aimed to compare the effects of dexmedetomidine infusion versus placebo on postoperative narcotics requirement, complications, and oral intake.
Inadequate pain relief after cardiac surgery increases morbidity and results in a high incidence of persistent poststernotomy pain syndrome. The use of special opioid-based analgesia causes adverse effects such as nausea, vomiting, sedation, urinary retention, respiratory depression and delayed tracheal extubation. Regional anesthesia techniques such as pectoralis nerve block and serratus anterior block provide analgesia in the sternum and pain relief in the lateral / posterior chest Wall. Erector spinae (ESP) block, a new and simple myofascial block, provides wide multi-dermatomal sensory block. In the T5 spinous process, bilateral ESP block provides analgesia from T2 to T9 sensory level, resulting in both somatic and visceral analgesia by blocking both the dorsal and ventral of the spinal nerves, including the sympathetic chain. This block may provide adequate analgesia for median sternotomy because the main nerve supply to the sternal region is from T2 to T6. Median sternotomy incision and mediastinal tube regions are the major source of pain in patients undergoing cardiac surgery. The anterior and posterior branches of the intercostal nerves give nerves to the sternum. Parasternal local anesthetic infiltration around the sternum is effective in providing early postoperative analgesia and reducing opioid requirements and therefore has positive effects on healing. This simple and fast technique can be used even for anticoagulated patients.
The Investigators verify the effectiveness of "Binaural Beats" as premedication instrument in elderly patients submitted to orthopedic surgery to reduce anxiety , post operative pain and morphine consumption
We studied the effect of dextromethorphan (DEX), an N-methyl-d-aspartate antagonist, on analgesic consumption and pain scoring after abdominal hysterectomy. Our aim was to compare the analgesic effectiveness and incidence of adverse side effects of oral DEX with placebo (P)
