Context:This study evaluated the effectiveness of paravertebral block as an alternative anesthetic technique for extracorporeal shock wave lithotripsy (ESWL) procedure. A total of 50 patients with renal stones, aged 20-60 years, were randomly allocated into two groups; 25 patients in group P; received unilateral paravertebral block from T8 through L1 with injection of 5 mL 0.5% bupivacaine and 25 patients in group L; received local infiltration by bupivacaine 0.25% (2 mg/kg) into the 30 cm2 area after localizing the stones site, 10 min before the session. A total of 10 mm visual analogue scale (VAS) was used to evaluate pain every 10 min during the session. At the end of the procedure, total doses of rescue analgesia, the number of shockwaves, their power, and the total duration of shockwave treatment were recorded. After completion of the procedure, the patient was assessed for pain and nausea in the postanesthesia care unit (PACU) using the VAS. Patient's satisfaction and time needed to discharge patients to home also were recorded. Time to do the anesthetic technique was significantly higher (P < 0.001) in group-P than group-L, it was 12.7 ± 2.3 min versus 6.9 ± 1.9 min, respectively; intraoperative rescue analgesia by fentanyl was lesser (P < 0.001) in group-P than group-L, 26.7 ± 6.32 mcg versus 78.6 ± 5.41 mcg, respectively, also time interval between ends of the procedure till discharge to home was significantly higher (P < 0.001) in group-P than group-L, it was 99 ± 17 min versus 133 ± 31 min, respectively. VAS was not significant difference between both groups either intraoperative or postoperative in first hour. Patient's satisfaction was significantly higher (P < 0.05) in group-P than group-L, it was 8.8 ± 1.1 versus 6.1 ± 0.6, respectively. Adverse events were lesser, but not significant in group-P than in group-L. Two patients (8%) in group-L and one patient (4%) in the group-P experienced episodes of postoperative nausea and vomiting (PONV).Paravertebral block is an effective alternative anesthesia for outpatient lithotripsy; multiple level paravertebral blocks provide an optimal anesthetic condition, with acceptable adverse events for ESWL. And, providing proper analgesia during the procedure and in first hour after finishing of the procedure, early discharge to home and providing better patient's satisfactions.Aims:This study evaluated the effectiveness of paravertebral block as an alternative anesthetic technique for ESWL procedure.Settings and Design:Prospective open label study.Subject and Methods:A total of 50 patients with renal stones, aged 20-60 years, were randomly allocated into two groups; 25 patients in group P; received unilateral paravertebral block from T8 through L1 with injection of 5mL 0.5% bupivacaine and 25 patients in group L; received local infiltration by bupivacaine 0.25% (2 mg/kg) into the 30 cm2 area after localizing the stones site, 10 min before the session. A total of 10 mm VAS was used to evaluate pain every 10 min during the session. At the end of the procedure, total...
Objectives: Transversus abdominis plane (TAP) block and local anesthetic wound infiltration (LAI) can provide a variable effective pain relief at the wound site after surgery. This prospective study was designed to evaluate the postoperative analgesic efficacy of TAP with or without dexmedetomidine compared with LAI of the wound after herniorrhaphy. Materials and methods:Sixty adult patients were divided into 3 groups of 20 patients each. Group1 (TAPD): Patients received single shot ultrasound-guided (US) TAP block using 15 mL of levobupivacaine 0.5% mixed with 0.9 μg/kg of dexmedetomidine. Group 2 (TAP): Patients received single shot US guided TAP block using 15 mL of levobupivacaine 0.5%. Group 3 (LAI): Patients received local anesthetic infiltration (LAI) patients received local infiltration using 15 mL of levobupivacaine 0.5%. The following parameters were assessed at, 2, 10, 18 and 24 h postoperatively: postoperative duration of analgesia, analgesic pain scores using the visual analogue scale (VAS) for pain, amount of supplemental intravenous morphine, postoperative nausea and vomiting during 24 h. Results:We found that a lower significant difference (P<0.05) of VAS pain scores at rest and on movement between group TAPD and group TAP at time 24 h postoperatively. Also, there was a lower significant difference (P<0.05) of VAS pain scores at rest and on movement between group TAPD and group LAI at 10, 18 and 24 h. Moreover, there was a lower significant difference (P<0.05) between group TAP and group LAI at times 10 and 18 h. Also, supplemental morphine consumption within 24 h was a statistically higher (P<0.05) in group LAI compared to groups TAPD and TAP. Conclusion:Using dexmedetomidine as an additive to levobupivacaine in ultrasound-guided TAP block for herniorrhaphy provides prolonged duration of postoperative analgesia, and lowered VAS pain scores. Also local anesthetic infiltration can give accepted postoperative analgesia but with shorter duration than TAP block
Background: A combined adductor canal block (ACB) and sciatic nerve block (SNB) is new different way to achieve an efficient postoperative analgesia after total knee replacement (TKR) that spares the weakness of quadriceps femoris muscle. This prospective randomized controlled trial aimed to evaluate the efficiency and safety of the combined adductor canal with sciatic nerve blocks versus local analgesic infiltration alone for pain control after total knee replacement.
Airway management continues to be a challenging task for healthcare practitioners and when it comes to critical settings; it carries more challenges even for the skilled persons. Critical settings could be in fact of suits; where intervention takes place, equipment or practitioners taking care of airway management. Critically ill patients with multiple comorbidities, increasing oxygen demand and high respiratory work; that may require elective airway securing. Various protocols, guidelines and recommendations advocated for this task with the prospects of less hemodynamic alteration and prevention of pulmonary aspiration. In the former, starting oxygen therapy for all critical patients on admission was a routine following the concept; if some is good, more must be better. Nowadays excess oxygen may be unfavorable in some acute critical conditions e.g. ischemic strokes, post-acute myocardial infraction and those with hypercapnic respiratory failure. However, still high flow inspired oxygen concentration is the protocol until they are stable then its reduction to reach the targeted arterial oxygen saturation. Oxygen devices used for oxygen delivery are plenty and its selection depends on the many factors; airway patency, patient’s conscious level and compliance, and assessment of gas exchange based on arterial blood sample which is recommended for all critically ill patients. Early prompt evaluation of the airway and assessment of gas exchange using arterial blood sample analysis is curial in all critically ill patients to guide for subsequent oxygen supply and whether the patient needs ventilatory support or not. This chapter will focus on airway management, oxygen therapy and types of ventilatory support required for adult critically ill patients, while other situations’ airway management’s tools and skills will be discussed in another ones.
