Filter by:Thoracic epidural analgesia (TEA) is the gold standard analgesia of the laparotomy in major abdominal surgery and can be associated with intravenous lidocaine or subtituted by intravenous lidocaine when TEA is contraindicated and in order to reduce the use of the morphinics in the perioperative period. Side effects can be paralytic ileus or nausea and vomiting and delay the enhanced recovery after surgery. Intravenous lidocaine and TEA share several properties like anti hyperalgesia, anti inflammatory effect, intestinal process, anti tumoral effect… which suggests an additive effect of their combination that was not studied yet.
Osteoarthritis (OA) is a chronic and progressive disease that results from characteristic pathological changes in the tissues of the entire joint, resulting in failure in the component parts. OA is one of the most common causes of disability in adults due to pain and altered joint function, impacting patients' quality of life. Treatment is based on decreasing pain and improving function, involving non-pharmacological, pharmacological, and surgical management. First-line treatment involves non-pharmacological and pharmacological measures. When OA is very advanced, total joint replacement surgery is recommended. However, for patients refractory to conservative treatment and unwilling or unable to undergo arthroplasty, few options remain. Recently, several studies involving minimally invasive procedures are being recommended. Among them is the cooled radiofrequency technique, causing neurotomy by thermal activity, thus reducing the patient's perception of pain. The classical therapeutic target for this technique are the genicular nerves of the knee. However, more recent studies have shown that these classical targets do not provide complete pain relief and have suggested new therapeutic targets, comprising besides the genicular nerves, the recurrent peroneal nerve and the infra-patellar branch of the saphenous nerve. In order to validate these revised targets, new studies need to be done. Therefore, the aim of the present study is to evaluate the efficacy of the cooled radiofrequency procedure using classical and revised targets, and to compare pain intensity, knee function, quality of life, analgesic consumption and adverse effects of both techniques. Key words: Osteoarthritis of the knee. Sensory nerve denervation. Classical targets. Revised targets.
This study aims to compare single level serratus block versus bilevel serratus block with and without dexmedetomidine in cancer patients undergoing modified radical mastectomy for breast cancer regarding pain control and possible side effects.
OBJECTIVE: The purpose of this study was to compare the efficacy of Ketorolac versus Paracetamol as an adjunct to Nalbuphine in the management of post-operative pain following elective cardiac surgery. STUDY DESIGN: Randomized (single-blind) control trial. SAMPLING TECHNIQUE: Computer generated, randomized selection of patients with 50% probability of assignment into either group. PLACE AND STUDY DURATION: (single center) SICU at the National Institute of Cardiovascular Diseases Hospital, Karachi over a period of six months, from January 1, 2021 up to June 30, 2021. METHODS: Sixty patients (30 in each group) were randomly assigned to receive either Paracetamol (control) or Ketorolac (treatment), along with the usual Nalbuphine infusion, over the first 48 hours postoperatively. The control group received injection Paracetamol 1gm six hourly, whereas treatment group received injection Ketorolac 30mg eight hourly. PRIMARY OUTCOME: The VAS (pain score) was evaluated at 6, 12, 18 and 24 hours post-extubation and a score of 4 or less was taken as a cut-off for adequate pain control. SECONDARY OUTCOMES: The time taken to extubation postoperatively. The total dose of Nalbuphine administered to each patient and total chest tube drainage recorded over 48 hours postoperatively.
The investigators will conduct a prospective, randomized, double-blinded study using an axillary brachial plexus block in patients undergoing elective surgery of the distal forearm and hand to characterize and describe the pharmacokinetics of bupivacaine associated with perineural dexamethasone. The pharmacokinetic analysis will be performed by measuring bupivacaine plasma levels at different time intervals after the blockade (15, 30, 45, 60, and 90 minutes), allowing comparison between 2 different groups: Bupivacaine (B) and Bupivacaine-dexamethasone (BD). Thus, the hypothesis is that plasma levels of bupivacaine during the first 90 minutes after a blockade are lower in the presence of perineural dexamethasone, suggesting a decrease, at least initially, in systemic absorption from the injection site.
Spinal anesthesia is the most consistent block for lower abdomen and lower limb surgical procedures. Over years many drugs have been used as an additive to spinal anesthesia in order to prolong the duration of action and to provide adequate postoperative analgesia. Dexmedetomidine, a highly selective α2 agonist is rapidly emerging as the choice of additive to spinal anesthesia in view of its property to provide analgesia however, it may be associated with bradycardia which may affect the hemodynamic stability. Nalbuphine is an opioid with agonist actions in the kappa receptor and antagonist actions in the mu receptor, it produces analgesia and sedation and lesser side effects through antagonism at the mu receptor but, it could be associated with some side effects as: dizziness, bradycardia, nausea, vomiting, and pruritus and may be associated with respiratory depression.
Cesarean birth is a common surgical procedure. After cesarean birth, postsurgical pain may delay recovery, interfere with maternal-newborn bonding, and reduce the breastfeeding if not adequately controlled. Postpartum analgesia has become a common concern. Many adjuvant drugs used for peripheral nerve blocks as( N-methyl-d-aspartate (NMDA) receptor antagonists , Magnesium , Ephedrine , Dexamesathone , Fentanyl , Midazolam and Neostigmine) Dexmedetomidine is a potent and highly selective α2 adrenergic receptor agonist, exerts its sympatholytic effect by inhibiting the release of noradrenaline from central and peripheral sympathetic nerve endings. It is considered to be a useful agent with a wide safety margin, excellent sedative capacity and moderate analgesic properties
Postoperative evaluation of patients who did and did not do preoperative abdominal breathing exercises.
Caffeine is the most widely consumed psychoactive drug in the world. Natural sources of caffeine include coffee, tea, and chocolate. Synthetic caffeine is also added to products to promote arousal, alertness, energy, and elevated mood. We designed this prospective observational study to determine if caffeine consumption would influence intraoperative analgesic consumption
One way to reduce pain during epidural needle insertion is infiltration of lidocaine using a needle. However, infiltration of lidocaine using the needle alone is a painful process. Free needle infiltration of lidocaine can be an alternative to reduce epidural needle insertion pain. The study of Gozdemir et al. found that 10% lidocaine infiltration without needle was less painful than 2% lidocaine infiltration with a 27G needle with no significant difference in analgesia effect during epidural needle insertion. This study aimed to compare infiltration of lidocaine with and without needle for epidural needle insertion in a double-blind study, using a Tuohy needle, Comfort-inTM injector, and wider surgical group as novelty from previous studies. This study was a double blind randomized controlled trial. Data collection was carried out consecutively on 84 subjects with 42 subjects in each group of lidocaine infiltration without needles and lidocaine infiltration with 23G needles. The effectiveness of analgesia was assessed from three variables like pain with a Numeric Pain Rating Scale (NPRS) of 0 to 10 during lidocaine infiltration, pain with NPRS during epidural needle insertion, and patient movement during epidural needle insertion.
