Background The efficacy and safety of patient-controlled epidural analgesia (PCEA) for postoperative analgesia on hospital wards was studied. Methods Postoperative analgesia was provided for 1,030 patients with PCEA using 0.05% bupivacaine and fentanyl, 4 microg/ml, in a standardized manner. Patients were seen at least twice a day by the staff of the anesthesia pain management service. Prospectively gathered data included verbal pain scores at rest and activity (0-10); consumption of bupivacaine and fentanyl; and incidences of pruritus, nausea, sedation, hypotension, motor block, and respiratory depression. Descriptive statistics were used. Risk factors for side effects were determined using logistic regression. Results The study included 552 women and 477 men who underwent a median (mode) of 3 (2) days of PCEA. Their mean age was 59 +/- 16 yr and their mean weight was 76 +/- 19 kg. There were 454 abdominal, 165 gynecologic, 126 urologic, 108 vascular, 90 thoracic, 83 orthopedic, and 4 plastic surgical procedures. Median (mode) pain scores were 1 (0) at rest and 4 (5) with activity on postoperative day 1. Incidences of side effects were 16.7% (pruritus), 14.8% (nausea), 13.2% (sedation), 6.8% (hypotension), 2% (motor block), and 0.3% (respiratory depression). Reasons for termination of PCEA were elective (82%), displaced epidural catheter (12%), anticoagulation (3%), infection (1%), side effects (1%), inadequate analgesia (1%), and other (<1%). Risk factors for side effects were female sex, patient weight <73 kg, patient age <58 yr, bupivacaine and fentanyl consumption >9 ml/h, use of analgesic adjuncts, and lumbar placement of epidural catheters. Conclusion Patient-controlled epidural analgesia provides effective and safe postoperative analgesia on hospital wards.

Satisfactory Analgesia

Background/Aim. Hip replacement surgery can initiate significant postoperative pain caused by bone alterations, implant, and soft tissue or nerve injuries. Postoperative analgesia using regional techniques has been shown to have numerous advantages over the intravenous use of morphine. However, numerous side effects and complications of postoperative continuous epidural analgesia have been reported recently. The aim of this prospective, randomized study was to investigate whether continuous lumbar plexus block can be a safe and efficacious alternative for postoperative analgesia in comparison with epidural analgesia and patient-controlled analgesia with morphine (PCA morphine) for hip arthroplasty. Methods. This prospective study included 60 patients, scheduled for total hip arthroplasty. Patients were randomized into 4 groups: the group central nerve block ? epidural (CNB), the group peripheral nerve block ? lumbar plexus block (PNB), the group spinal anesthesia-PCA morphine (SAM) and the group general anesthesia-PCA morphine (GAM). The quality of analgesia and side effects (hypotension, nausea, vomiting, urinary retention) were recorded in all groups at 4 h, 12 h, and 24 h after surgery. Pain scores were assessed using Visual Analogue Scale (VAS), both at rest and on moving. Results. Our findings demonstrated that the use of a continuous lumbar plexus block provides effective analgesia at rest and on moving, during 24 h after hip arthroplasty. Pain scores varied significantly among the groups 4 h postoperatively (F = 21.827; p < 0.01), 12 h postoperatively (F = 41.925; p < 0.01) and 24 h postoperatively (F = 33.768; p < 0.01) with the highest scores ? 3 in the GAM group. Patients from the PNB group had satisfactory analgesia, comparable with patients from the CNB group. The incidence of nausea was significantly lower in the PNB group 12 h after the operation (?2 = 9.712; p < 0.01). The incidence of urine retention was significantly different 12 h after the operation, with a presence only in the CNB group, with the incidence of 33.3% (?2 = 16.365; p < 0.01). In all studied groups, the incidence of hypotension was not significantly different postoperatively. Conclusion. Administration of postoperative analgesia using continuous lumbar plexus block produces satisfactory analgesia with a low incidence of side effects when compared to epidural analgesia or parenteral opioids following hip arthroplasty.

Background Epidural meperidine is effective for postoperative analgesia, but the optimum dose has not been evaluated. Methods Five doses of epidural meperidine (12.5, 25, 50, 75, and 100 mg) given at the first request for analgesia after cesarean section were compared. Visual analog pain scores, duration of analgesia as defined by time to first patient-controlled epidural analgesia demand, plasma concentrations of meperidine, side effects, and subsequent 24-h consumption of meperidine were evaluated. Results All doses were effective, but patients took longer to become pain-free after 12.5 mg (median 30 min) compared with 25 mg (median 12 min, P = 0.038), and duration of analgesia was shorter after 12.5 mg (median 83 min) compared with 25 mg (median 165 min, P = 0.0005). Increasing dose to more than 25 mg did not improve onset or duration of analgesia. Plasma concentrations of meperidine were less than minimum effective analgesia concentration for all doses except 100 mg. There was more frequent nausea (P = 0.004) and dizziness (P = 0.0002) after 100 mg compared with smaller doses. Conclusions Epidural meperidine provides effective postoperative analgesia, although of relatively short duration. A single dose of 25 mg is superior to 12.5 mg, but there is no benefit from increasing the dose to 50 mg or greater.

Abstract The use of opioids in intrathecal or epidural anesthesia has become popular to optimize postoperative analgesia. However, opioid-induced side effects, such as respiratory depression, nausea, vomiting, urinary retention and pruritus, limit their use. Several investigations have shown that intrathecal or epidural administration of opioids produces a dose dependent modulation of spinal nociceptive processing in animals and humans and is not associated with sedation. Aim of Study The purpose of this study was to assess the spinally mediated analgesic effects postoperativally of intrathecal Nalbuphine plus bupivacaine after lower abdominal surgeries in comparison to intrathecal bupivacaine plus fentanyl Patients & Methods : 60 patients came to Ain-shams Hospital for lower abdominal surgeries, They were randomly allocated into two equal groups (30 patients each) group F and group N. Group F : Bupivacaine-Fentanyl Patients received an intrathecal injection of 3 ml of 0.5% heavy (hyperbaric) bupivacaine plus 0.5 ml (25 µg) fentanyl. Group N: Bupivacaine-Nalbuphin Patients received an intrathecal injection of 3 ml of 0.5% heavy (hyperbaric) bupivacaine plus 0.5 ml (0.5 mg) Nalbuphine. All patients were assessed and monitored for: Hemodynamics: ECG for heart rate, and non-invasive arterial pressure, respiratory rate and arterial oxygen saturation, onset of sensory block, onset of motor block, duration of analgesia & 1st rescue analgesia, duration of motor block, adverse effects as: hypotension, bradycardia, respiratory depression, pruritus, shivering, nausea and vomiting were recorded. Results & Conclusion Addition of a small dose of nalbuphine or fentanyl to bupivacaine in spinal anesthesia moderately prolonged the time of postoperative analgesia the duration of postoperative analgesia is nearly the same in nalbuphine group & the fentanyl group. There is more rapid onset of motor block in fentanyl group than in nalbuphine group but with no difference in sensory or motor block regression. No respiratory depression or degree of sedation occurs in both groups. Hemodynamic stability & side effects incidence are the same in both groups

Introduction: Caudal block is a routinely performed analgesic and anaesthetic technique in paediatric population undergoing various infra-umbilical surgeries. Various adjuvants have been used along with local anaesthetics like ropivacaine in single-shot caudal block for enhancing postoperative analgesia in paediatric infra-umbilical surgeries. Aim: To evaluate the efficacy of dexamethasone used as an adjuvant to 0.2% ropivacaine in caudal block for postoperative analgesia in paediatric patients. Materials and Methods: This was a randomised doubleblinded controlled study conducted on 80 paediatric patients (8 months-8 years), with American Society of Anesthesiologists (ASA) physical status I or II undergoing various infra-umbilical surgeries,at a tertiary care teaching institute from April 2019 to September 2019. These total subjects were randomly allocated into two groups. GroupR (n=40) administered 0.2% ropivacaine (1 mL/kg) while GroupRD (n=40) administered 0.2% ropivacaine (1 mL/kg) with dexamethasone (0.1 mg/kg) in caudal block. The duration of analgesia, postoperative pain scores (Face Legs Activity Cry Consolability (FLACC) score), rescue analgesic consumption in 24 hours, haemodynamic changes and side-effects were noted. The rescue analgesic (paracetamol 15 mg/kg oral) was given whenever FLACC ≥4. Standard qualitative and quantitative tests (unpaired student t-test, Chi-square test) were used to analyse and compare the results obtained. Results: The mean duration of analgesia was significantly longer in Group RD (745.21±146.91 min) as compared to GroupR (440.38±76.44 min); (p-value <0.001). The significantly lower FLACC pain scores were noted in patients in Group RD compared to Group R; (p-value <0.05). The rescue analgesic consumption was significantly lesser in Group RD in terms of requirement of number of doses of rescue analgesic than in Group R; (p-value <0.05). No significant haemodynamic changes or side-effects were observed in both groups; (p-value >0.05). Amongst postoperative complications noted, fever was observed in 1 patient (3.33%) and PONV in 2 patients (6.66%) in Group R. None complications were observed in the patients of RD group. Conclusion: Dexamethasone (0.1 mg/kg) was found to be safe and effective adjuvant to 0.2% ropivacaine for caudal block in children undergoing various infra-umbilical surgeries.

Background The risk of bacterial contamination related to epidural analgesia in patients cared for in the intensive care unit has not been assessed. Thus the authors studied patients who received care in the intensive care unit who were given epidural analgesia for more than 48 h to determine the rates of local, epidural catheter, and spinal space infection and to identify risk factors. Methods Each patient receiving epidural analgesia for longer than 48 h was examined daily for local and general signs of infection. A swab sample for culture was taken if there was local discharge; all epidural catheters were cultured on withdrawal. All patients underwent weekly neurologic monitoring for 1 month; those with positive epidural catheter cultures had one spinal magnetic resonance image scan. Results The 75 patients cared for in the intensive care unit who were studied had been receiving epidural analgesia for a median of 4 days (interquartile range, 3.5 to 5 days). Twenty-seven patients had signs of local inflammation (erythema or local discharge), and nine of these had infections. All the patients who had both local signs also had infection. All nine infections were local (12%), but four patients also had epidural catheter infections (5.3%). No patient with erythema alone or without local signs had a positive epidural catheter culture. No spinal space infection was diagnosed. Staphylococcus epidermidis was the most frequently cultured microorganism. Local infection was treated by removing the epidural catheter without any antibiotics. Concomitant infection at other sites (21 of 75 patients, or 28%), antibiotic therapy (64 of 75 patients, or 85%), the duration of epidural analgesia, and the insertion site level of the epidural catheter were not identified as risk factors for epidural analgesia-related infections. Conclusions The risk of epidural analgesia-related infection in patients in the intensive care unit seems to be low. The presence of two local signs of inflammation is a strong predictor of local and epidural catheter infection.

This chapter discusses postcraniotomy headache (PCH), a common yet frequently underdiagnosed and undertreated occurrence, with up to 30% of patients experiencing persistent headache after surgery. The chapter identifies risk factors for the development of acute and persistent PCH and describes mechanisms for its development, such as injury to the sensory nerves supplying the scalp and underlying tissues or to the perivascular nerves that supply sensation to the dura mater. Pain management following craniotomy is a balancing act of achieving adequate analgesia while avoiding oversedation, respiratory depression, hypercapnia, nausea, vomiting, and hypertension. Current evidence suggests that a balanced, multimodal approach to the treatment of acute PCH is often required to optimize pain control, minimize undesired side effects, and prevent the development of persistent PCH.

Aim.To investigate the effect of magnesium administered to the operative region muscle and administered systemically on postoperative analgesia consumption after lumbar disc surgery.Material and Method.The study included a total of 75 ASA I-II patients aged 18–65 years. The patients were randomly allocated into 1 of 3 groups of 25: the Intravenous (IV) Group, the Intramuscular (IM) Group, and the Control (C) Group. At the stage of suturing the surgical incision site, the IV Group received 50 mg/kg MgSO4intravenously in 150 mL saline within 30 mins. In the IM Group, 50 mg/kg MgSO4in 30 mL saline was injected intramuscularly into the paraspinal muscles. In Group C, 30 mL saline was injected intramuscularly into the paraspinal muscles. After operation patients in all 3 groups were given 100 mg tramadol and 10 mg metoclopramide and tramadol solution was started intravenously through a patient-controlled analgesia device. Hemodynamic changes, demographic data, duration of anesthesia and surgery, pain scores (NRS), the Ramsay sedation score (RSS), the amount of analgesia consumed, nausea- vomiting, and potential side effects were recorded.Results.No difference was observed between the groups. Nausea and vomiting side effects occurred at a rate of 36% in Group C, which was a significantly higher rate compared to the other groups (p<0.05). Tramadol consumption in the IM Group was found to be significantly lower than in the other groups (p<0.05).Conclusion.Magnesium applied to the operative region was found to be more effective on postoperative analgesia than systemically administered magnesium.

A prospective survey of one thousand and sixty-two patients receiving epidural analgesia in surgical wards was undertaken over a two-year period. The duration of infusion ranged from one to fourteen days, with a mode of three days. There were 1131 episodes where a local anaesthetic and opioid mixture was used and 160 where opioids were used alone. Local anaesthetic was not used without opioids. 23% of catheters were removed prematurely because of catheter related problems including accidental dislodgement (13%) and skin site inflammation (5.3%). No epidural abscess or haematoma was identified. In 14% of the total number of episodes there was either no demonstrable block or complications occurred requiring a change of solution: 30% of this group were salvaged following intervention by the Acute Pain Service (APS). The incidence of respiratory depression was 0.24%. There was no case of delayed respiratory depression. Epidural analgesia can be used safely in surgical wards provided that regular review of the patients is undertaken. It must be anticipated however, that up to 20% of patients will not receive adequate analgesia for the first 48 hours postoperatively. The failure rate could be halved if accidental dislodgement of epidural catheters could be eliminated.

Background Ropivacaine, 0.2%, is a new local anesthetic approved for epidural analgesia. The addition of 4 microg/ml fentanyl improves analgesia from epidural ropivacaine. Use of a lower concentration of ropivacaine-fentanyl may further improve analgesia or decrease side effects. Methods Thirty patients undergoing lower abdominal surgery were randomized in a double-blinded manner to receive one of three solutions: 0.2% ropivacaine-4 microg fentanyl 0.1% ropivacaine-2 microg fentanyl, or 0.05% ropivacaine-1 microg fentanyl for patient-controlled epidural analgesia after standardized combined epidural and general anesthesia. Patient-controlled epidural analgesia settings and adjustments for the three solutions were standardized to deliver equivalent drug doses. Pain scores (rest, cough, and ambulation), side effects (nausea, pruritus, sedation, motor block, hypotension, and orthostasis), and patient-controlled epidural analgesia consumption were measured for 48 h. Results All three solutions produced equivalent analgesia. Motor block was significantly more common (30 vs. 0%) and more intense with the 0.2% ropivacaine-4 microg fentanyl solution. Other side effects were equivalent between solutions and mild in severity. A significantly smaller volume of 0.2% ropivacaine-4 microg fentanyl solution was used, whereas the 0.1% ropivacaine-2 microg fentanyl group used a significantly greater amount of ropivacaine and fentanyl. Conclusions Lesser concentrations of ropivacaine and fentanyl provide comparable analgesia with less motor block despite the use of similar amounts of ropivacaine and fentanyl. This finding suggests that concentration of local anesthetic solution at low doses is a primary determinant of motor block with patient-controlled epidural analgesia after lower abdominal surgery.

Background and methods: Intrathecal opioids (ITOs) have been used for decades to control postoperative pain. Intrathecal opioid dosing is limited, however, by opioid-related side effects, most importantly respiratory depression. To overcome these limitations, we combined intrathecal morphine with a continuous intravenous (IV) postoperative naloxone infusion to control opioid-related side effects. The purpose of this study is to document the efficacy and safety of high-dose intrathecal morphine combined with postoperative naloxone infusion to provide postoperative analgesia after major surgery. After IRB approval, a retrospective chart analysis was performed on 35 patients who had a radical prostatectomy from 2004 to 2006. All patients received a single injection of ITOs before anesthesia, a typical general anesthestic, followed by naloxone infusion at 5 μg/kg/h started 1 hour post-ITOs and continued for 22 hours postoperatively. The following information was collected: patient age, height, weight, anesthesia technique/time, and dose of ITOs given. Postoperative pain relief was assessed for 48 hours using the Visual Analog Score (VAS) for pain (0, no pain; 10, worst pain), perioperative opioid use, NSAID consumption, and ability of patient to ambulate. The safety of this novel treatment was assessed with opioid-related side effects and vital signs. All data are reported as mean (SD).Results: Mean ITOs given were morphine 1.3 (0.3) mg combined with fentanyl 56 (9) μg. The intrathecal morphine dose ranged from 0.8 to 1.7 mg. The mean worst pain VAS in the first 12 hours postoperatively was only 1.0 (1.7). The first NSAID dose was given 6.6 (3.1) hours post-ITOs. The first opioid on the floor was given an average of 22.6 (14.5) hours post-ITOs. A mean of only 5.7 (12.3) morphine equivalents were required on postoperative day 1 (POD 1). On POD 2, the mean worst pain VAS was only 2.6 (2.2) with only 5.7 (6.2) morphine equivalents needed to provide pain relief. On POD 1, 25 patients required no additional opioids for their entire hospital stay. Overall, 11 of 35 patients did not require any additional postoperative opioids. Thirtyfour patients (97 percent) were able to ambulate in the first 12 hours postoperatively. No opioid-induced respiratory depression was observed. Opioid-related side effects (pruritus, nausea) were infrequent and minor.Conclusions: High-dose ITOs combined with postoperative IV naloxone infusion provided excellent analgesia for radical prostate surgery. IV naloxone infusion appeared to control opioid side effects without diminishing the analgesia. No serious adverse effects were noted.
