Effectiveness of Patient-Controlled Intravenous Analgesia (PCIA) with Sufentanil Background Infusion for Post-Cesarean Analgesia: A Randomized Controlled Trial. J Pain Res 2022; 15:1355-1364. [PMID: 35573842 PMCID: PMC9091317 DOI: 10.2147/jpr.s363743] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Accepted: 04/29/2022] [Indexed: 11/23/2022] Open
Abstract
Purpose To investigate the effectiveness of sufentanil patient-controlled intravenous analgesia pump (PCIA) and background infusion in patients of post-cesarean analgesia. Patients and Methods This trial compared two groups of women undergoing cesarean section and receiving PCIA: no background infusion group (n=30), 6-min lockout time, and background infusion group (n=30), 2 mL/h infusion, 10-min lockout time. Both groups with 2 μg/kg sufentanil was diluted to 100 mL with normal saline. VAS scores at rest at 36 h was the primary endpoint. The secondary endpoints were the VAS scores at rest at 6, 12, and 24 h, the total amount of sufentanil consumed, the Ramsay sedation score (RSS) assessed at the same time points, postpartum bleeding within 24 h, the injection/attempt (I/A) ratio, BP and HR, PONV, side effects of sufentanil. Results Compared with the no background infusion group, the background infusion group showed lower VAS pain scores at 6, 12, and 24 h (P<0.01), but no differences at 36 h (95% CI = -0.5-0.8. P>0.05). Attempts, injections, and total sufentanil consumption were significantly different between the two groups (P<0.001), but without difference in I/A. Bleeding was less in the background infusion group at 1 h (P=0.03). The minimal respiration rates were not significantly different between groups. Conclusion Background infusion increased the total consumption of sufentanil within 36 h after cesarean section. Although it did not reduce uterine contraction pain and wound pain at 36 h, it significantly reduced the pain at 6, 12, and 24 h after cesarean section. It improved patient satisfaction and reduced the amount of bleeding after 1 h. Importantly, it did not increase the incidence of hypertension, PONV and respiratory depression.

Abstract
Objective
To determine efficacy and safety of patient-controlled intravenous analgesia (PCIA) with tramadol and lornoxicam for postoperative analgesia, and its effects on surgical outcomes in patients after thoracotomy.
Summary of background data
Adequate pain relief after thoracic surgery is of particular importance, not only for keeping patients comfortable but also for reducing the incidence of postoperative complications. PCIA with tramadol and lornoxicam could be an acceptable alternative to patient-controlled epidural analgesia (PCEA) for pain management after thoracotomy.
Methods
The records of patients who underwent thoracotomy for lung resection between January 2014 and December 2014 at our institution were reviewed. The patients were divided into 2 groups according to postoperative pain treatment modalities. Patients of PCEA group (n = 63) received PCEA with 0.2% ropivacaine plus 0.5 μg/mL sufentanil, while patients in PCIA group (n = 48) received PCIA with 5 mg/mL tramadol and 0.4 mg/mL lornoxicam. Data were collected for quality of pain control, incidences of analgesia-related side effects and pulmonary complications, lengths of thoracic intensive care unit stay and postoperative hospital stay, and in-hospital mortality.
Results
Pain at rest was controlled well in both groups during a 4-day postoperative period. Patients in PCIA group reported significantly higher pain scores on coughing and during mobilization in the first 2 postoperative days. The incidences of side effects and pulmonary complications, in-hospital mortality, and other outcomes were similar between groups.
Conclusions
PCIA with tramadol and lornoxicam can be considered as a safe and effective alternative with respect to pain control and postoperative outcomes after thoracotomy.

J Pain Res 2020; 13:3095-3106. [PMID: 33262644 PMCID: PMC7699445 DOI: 10.2147/jpr.s281041] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/10/2020] [Accepted: 10/24/2020] [Indexed: 01/21/2023] Open
Abstract
Purpose We aimed to investigate the effect of a basal opioid infusion in fentanyl-based intravenous patient-controlled analgesia (IV-PCA) on postoperative opioid consumption, pain intensity, and occurrence of opioid-related side effects. Patients and Methods We retrospectively reviewed 2097 consecutive patients who received IV-PCA after elective general, thoracic, urologic, and plastic surgery under general anesthesia between June 2019 and October 2019. The patients were divided into two groups: IV-PCA with basal infusion (basal group) and IV-PCA without basal infusion (no basal group). We performed a propensity score matching (PSM) analysis to adjust for baseline differences between both groups. We compared the fentanyl PCA consumption (mcg), pain intensity, rescue analgesic administration, and occurrence of opioid-related side effects (nausea, vomiting, somnolence or dizziness, and overall side effects) during the first 48 hours postoperatively between the two groups before and after PSM. Results We analyzed 1317 eligible patients. Of these, 757 (57.5%) patients received IV-PCA without basal infusion. The PSM of the total cohort yielded 539 pairs of cases. After PSM, the fentanyl PCA consumption was significantly lower in the no basal group at 48 hours postoperatively as compared to the basal group (at 24 hours, the median difference: −80 mcg, P<0.001, 95% CI=−112 – −45 mcg; at 48 hours, the median difference: −286 mcg, P<0.001, 95% CI=−380 – −190 mcg), without significantly increasing pain intensity and administration of rescue analgesia. The occurrence of overall opioid-related side effects was also significantly lower in the no basal group (at 24 hours: 31.0% vs 23.0%, OR=0.67, P=0.003, 95% CI=0.51 – 0.87; at 48 hours: 18.9% vs 11.0%, OR=0.48, P<0.001, 95% CI=0.31 – 0.75). Conclusion Basal infusion of fentanyl-based IV-PCA was significantly associated with an increase in fentanyl consumption and the occurrence of opioid-related side effects in postsurgical patients.

Sublingual Sufentanil Tablet System Versus Continuous Morphine Infusion for Postoperative Analgesia in Cardiac Surgery Patients. J Cardiothorac Vasc Anesth 2020; 35:1125-1133. [PMID: 32951999 DOI: 10.1053/j.jvca.2020.08.030] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/08/2020] [Revised: 08/11/2020] [Accepted: 08/12/2020] [Indexed: 12/13/2022]
Abstract
OBJECTIVE(S) To assess the effectiveness and side effects of a patient-controlled sublingual sufentanil tablet system for postoperative analgesia after cardiac surgery and to compare it to a nurse-controlled continuous morphine infusion. DESIGN Prospective, open-label, randomized controlled trial. SETTING Single university academic center. PARTICIPANTS Adult patients undergoing cardiac surgery, which included a sternotomy. INTERVENTIONS Sublingual sufentanil tablet system versus nurse-controlled continuous morphine infusion. MEASUREMENTS AND MAIN RESULTS A total of 483 cardiac surgery patients were screened for eligibility, of whom 64 patients completed the study. No statistically significant differences were found for baseline characteristics between both groups. All mean numeric rating scale (NRS) pain scores from after extubation until intensive care unit discharge were ≤3 in both groups. The cumulative mean NRS pain score from 24 hours after extubation (primary outcome) (t = hours after extubation) was significantly different in favor of the morphine group: (t = 0-24) (0.8 [0.7] v 1.3 [0.8]; p = 0.006). Later cumulative mean pain scores were also in favor of the morphine group: (t = 24-48) (0.2 [0.3] v 0.6 [0.5]; p = 0.001) and (t = 48-63) (0.0 [0.0] v 0.1 [0.2]; p = 0.013). The cumulative opioid dose (in milligrams intravenous morphine equivalents) was significantly higher in the morphine group compared with the sublingual sufentanil group (241.94 [218.73] v 39.84 [21.96]; p = 0.0001). No differences were found for the incidences of postoperative nausea and vomiting, sedation, hypoventilation, bradycardia, or hypotension between both groups (secondary outcomes). CONCLUSIONS Despite resulting in statistically significantly higher pain scores, a patient-controlled sublingual sufentanil tablet system offers adequate analgesia after cardiac surgery and reduces opioid consumption when compared with continuous morphine infusion.

Influence of postoperative analgesia on systemic inflammatory response and postoperative cognitive dysfunction after femoral fractures surgery: a randomized controlled trial. Reg Anesth Pain Med 2019; 44:59-68. [PMID: 30640654 DOI: 10.1136/rapm-2018-000023] [Citation(s) in RCA: 34] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2018] [Revised: 03/24/2018] [Accepted: 06/27/2018] [Indexed: 11/04/2022]
Abstract
BACKGROUND AND OBJECTIVES To investigate the possible effect of postoperatively applied analgesics-epidurally applied levobupivacaine or intravenously applied morphine-on systemic inflammatory response and plasma concentration of interleukin (IL)-6 and to determine whether the intensity of inflammatory response is related to postoperative cognitive dysfunction (POCD). METHODS This is a randomized, prospective, controlled study in an academic hospital. Patients were 65 years and older scheduled for femoral fracture fixation from July 2016 to September 2017. Inflammatory response was assessed by leukocytes, neutrophils, C reactive protein (CRP) and fibrinogen levels in four blood samples (before anesthesia, 24 hours, 72 hours and 120 hours postoperatively) and IL-6 concentration from three blood samples (before anesthesia, 24 hours and 72 hours postoperatively). Cognitive function was assessed using the Mini-Mental State Examination preoperatively, from the first to the fifth postoperative day and on the day of discharge. RESULTS The study population included 70 patients, 35 in each group. The incidence of POCD was significantly lower in the levobupivacaine group (9%) than in the morphine group (31%) (p=0.03). CRP was significantly lower in the levobupivacaine group 72 hours (p=0.03) and 120 hours (p=0.04) after surgery. IL-6 values were significantly lower in the levobupivacaine group 72 hours after surgery (p=0.02). The only predictor of POCD in all patients was the level of IL-6 72 hours after surgery (p=0.03). CONCLUSIONS There is a statistically significant association between use of epidural levobupivacaine and a reduction in some inflammatory markers. Postoperative patient-controlled epidural analgesia reduces the incidence of POCD compared with intravenous morphine analgesia in the studied population. TRIAL REGISTRATION NUMBER NCT02848599.

Abstract
Objective: To compare the effectiveness of Morphine alone and Morphine with MgSo4 in pain management after CABG surgery. Methods: This randomized control trial was conducted in the department of anesthesia and critical care Choudhary Pervaiz Ellahi Institute of Cardiology, Multan from November 2016 to June 2017. All collected data was entered and analyzed by using computer software SPSS version 23.1. Quantitative data like age, VAS score was analyzed and presented as mean and standard deviation. Similarly qualitative data like gender and ASA status was calculated and presented as frequency and percentages. Independent sample T-test was applied for significance of VAS score. P value ≤0.05 was considered as significant. Results: A total number of 150 patients of both genders were included in this study. The main outcome variables of our study were VAS score. It was observed that, in group (M), the mean VAS score after 4, 12 and 24 hours of operation was 5.24±1.61, 5.8±2.27 and 5.44±2.27 respectively. And in group (MM), the mean VAS score after 4, 12 and 24 hours of operation was 4.36±2.58, 3.48±2.10 and 4.12±1.05 respectively. It was noted that both groups had statically significant difference of VAS score, as group (M) had higher VAS score than group (MM). Conclusion: Morphine with Mgso4 has better efficacy as compared to morphine alone when used as analgesic agent after CABG surgery.

Abstract
Background Postoperative pain is a complex process commonly caused by surgical trauma. It is one of the major concerns of patients undergoing heart surgery. Despite new techniques and modern analgesic treatments, postoperative pain is still one of the most important controversial issues. Methods 68 patients scheduled for elective CABG with CPB were included in a prospective, double-blind clinical trial. They were randomly divided into two groups. One group received PCA pump including morphine (group P) with underlying infusion of 0.02 mg/kg/Qh, bolus dose of 1 mg, lockout time of 15 minutes, and a maximum of 4 bolus of 0.02 mg/kg for one hour and the other group received morphine bolus (group B). Three patients were excluded from the study, and 33 and 32 patients participated in the groups P and B, respectively. Variables including age, gender, pump time, aortic clamp time, duration of surgery, complications (nausea and vomiting, GI Bleeding, and hypoxia), level of pain based on VAS, opioid consumption, hemodynamic, and sedation status were measured in both groups. Results There was no significant difference between the groups regarding age, gender, pump time, clamp time, duration of surgery, complication, sedation score, and hemodynamic status in most of the assessment periods. By assessing the pain severity in the groups at different periods, results showed a significant difference between the groups except at enrollment, and a lower severity of pain was noted in the group P compared to the group B. The consumed opioid was significantly higher in the group P than in the group B. However, higher doses of diclofenac and paracetamol were administered in the group B compared to the group P. Conclusions Results showed that higher morphine would be used in patients with PCA pump after extubation following heart surgery, and this increased dose of opioid was associated with better pain control and lack of complication. Therefore, PCA pump with underlying infusion could be effectively used in patients undergoing CABG that are directly assessed in intensive care unite.

Abstract
OBJECTIVE To conduct a systematic literature review (SLR) and quantitative analysis to assess the comparative efficacy and safety of the sufentanil sublingual tablet system (SSTS) against other available patient controlled analgesia (PCA) options for post-operative analgesia. METHODS An SLR was conducted for studies published between 2004 and 2016. Due to study heterogeneity, subgroup analyses were conducted controlling for differences in imputation methods for missing values, baseline pain severity, and type of surgery. Where sufficient data was available, a mixed treatment comparison (MTC) was performed. RESULTS The MTC and subgroup analyses used 13 studies. In direct meta-analysis, there was a statistically significant difference in favor of SSTS compared with intravenous (IV) PCA (morphine) at 24 hours for the patient global assessment (PGA) scores of "good" or "excellent". For the Pain Intensity Score, there were numerical but not statistically significant differences in favor of the SSTS versus IV PCA (morphine) and the patient controlled transdermal system (PCTS) (fentanyl) in the MTC at 6 hours (standardized mean difference -0.27 [credible interval -2.78, 2.09] and -0.36 [-3.89, 3.03], respectively). The onset of pain relief was earlier with the SSTS versus IV PCA (morphine) as shown by the Pain Intensity Difference. Likewise, the onset was earlier compared with PCTS (fentanyl) where data was available. There was a significant difference in favor of SSTS compared with IV PCA (morphine) and with PCTS (fentanyl) for any adverse event, and numerical improvements for withdrawals due to adverse events. CONCLUSIONS This meta-analysis shows that SSTS is an option for non-invasive management of moderate-to-severe post-operative pain which can be more effective, faster in onset and better tolerated than IV PCA (morphine) and PCTS (fentanyl).

Abstract
UNLABELLED Most patients who undergo surgical procedures experience acute postoperative pain, but evidence suggests that less than half report adequate postoperative pain relief. Many preoperative, intraoperative, and postoperative interventions and management strategies are available for reducing and managing postoperative pain. The American Pain Society, with input from the American Society of Anesthesiologists, commissioned an interdisciplinary expert panel to develop a clinical practice guideline to promote evidence-based, effective, and safer postoperative pain management in children and adults. The guideline was subsequently approved by the American Society for Regional Anesthesia. As part of the guideline development process, a systematic review was commissioned on various aspects related to various interventions and management strategies for postoperative pain. After a review of the evidence, the expert panel formulated recommendations that addressed various aspects of postoperative pain management, including preoperative education, perioperative pain management planning, use of different pharmacological and nonpharmacological modalities, organizational policies, and transition to outpatient care. The recommendations are based on the underlying premise that optimal management begins in the preoperative period with an assessment of the patient and development of a plan of care tailored to the individual and the surgical procedure involved. The panel found that evidence supports the use of multimodal regimens in many situations, although the exact components of effective multimodal care will vary depending on the patient, setting, and surgical procedure. Although these guidelines are based on a systematic review of the evidence on management of postoperative pain, the panel identified numerous research gaps. Of 32 recommendations, 4 were assessed as being supported by high-quality evidence, and 11 (in the areas of patient education and perioperative planning, patient assessment, organizational structures and policies, and transitioning to outpatient care) were made on the basis of low-quality evidence. PERSPECTIVE This guideline, on the basis of a systematic review of the evidence on postoperative pain management, provides recommendations developed by a multidisciplinary expert panel. Safe and effective postoperative pain management should be on the basis of a plan of care tailored to the individual and the surgical procedure involved, and multimodal regimens are recommended in many situations.

Abstract
BACKGROUND AND OBJECTIVE Adequate analgesia after sternotomy reduces postoperative adverse events. There are various methods of treating pain after heart surgery, such as infiltration with a local anesthetic, nerve block, opioids, non-steroidal anti-inflammatory drugs, alpha-adrenergic agents, intrathecal and epidural techniques, and multimodal analgesia. CONTENT A review of the epidemiology, pathophysiology, prevention and treatment of pain after sternotomy. We also discuss the various analgesic therapeutic modalities, emphasizing advantages and disadvantages of each technique. CONCLUSIONS Heart surgery is performed mainly via medium sternotomy, which results in significant postoperative pain and a non-negligible incidence of chronic pain. Effective pain control improves patient satisfaction and clinical outcomes. There is no clearly superior technique. It is believed that a combined multimodal analgesic regimen (using different techniques) is the best approach for treating postoperative pain, maximizing analgesia and reducing side effects.

Abstract
In this retrospective analysis of 10,575 patients who used fentanyl-based intravenous patient-controlled analgesia (IV-PCA) after surgery, we evaluated difference between young and elderly patients on their characteristic of adverse effects.We reviewed the data collected from the patients who were provided IV-PCA for pain control following elective surgery under either general or spinal anesthesia between September 2010 and March 2014. Postoperative pain, incidence of PCA-related adverse effects, and risk factors for the need of rescue analgesics and antiemetics for postoperative 48 hours were analyzed.Pain intensity (numerical rating scale [NRS]) at postoperative 6 to 12 hours (4.68 vs 4.58, P < 0.01) and incidence of nausea or vomiting (23.8% vs 20.6%, P < 0.001) were higher in young patients, while incidence of PCA discontinuation (9.9% vs 11.5%, P < 0.01) and sedation (0.1% vs 0.7%, P < 0.001) was higher in elderly patients. Despite larger fentanyl dose used, a greater proportion of young patients required rescue analgesics (53.8% vs 47.9%, P < 0.001) while addition of ketorolac was effective in reducing postoperative pain. Despite lower incidence of postoperative nausea and vomiting (PONV), a larger proportion of elderly patients required rescue antiemetics (10.1% vs 12.2%, P < 0.001) while addition of ramosetron was effective in reducing PONV.In conclusion, when fentanyl-based IV-PCA is used for postoperative pain control, a larger proportion of young patients may require rescue analgesics while elderly patients may require more rescue antiemetics. The addition of ketorolac or ramosetron to the PCA of young and elderly patients can be effective to prevent rescue analgesics or antiemetics use.

Abstract
BACKGROUND Many analgesics used in adult medicine are not licensed for pediatric use. Licensing limitations do not, however, justify that children are deprived of a sufficient pain therapy particularly in perioperative pain therapy. The treatment is principally oriented to the strength of the pain. Due to the degree of pain caused, intramuscular and subcutaneous injections should be avoided generally. NON-OPIOIDS The basis of systemic pain therapy for children are non-opioids and primarily non-steroidal anti-inflammatory drugs (NSAIDs). They should be used prophylactically. The NSAIDs are clearly more effective than paracetamol for acute posttraumatic and postoperative pain and additionally allow economization of opioids. Severe side effects are rare in children but administration should be carefully considered especially in cases of hepatic and renal dysfunction or coagulation disorders. Paracetamol should only be taken in pregnancy and by children when there are appropriate indications because a possible causal connection with bronchial asthma exists. To ensure a safe dosing the age, body weight, duration of therapy, maximum daily dose and dosing intervals must be taken into account. Dipyrone is used in children for treatment of visceral pain and cholic. According to the current state of knowledge the rare but severe side effect of agranulocytosis does not justify a general rejection for short-term perioperative administration. OPIOIDS In cases of insufficient analgesia with non-opioid analgesics, the complementary use of opioids is also appropriate for children of all age groups. They are the medication of choice for episodes of medium to strong pain and are administered in a titrated form oriented to effectiveness. If severe pain is expected to last for more than 24 h, patient-controlled anesthesia should be implemented but requires a comprehensive surveillance by nursing personnel. KETAMINE Ketamine is used as an adjuvant in postoperative pain therapy and is recommended for use in pediatric sedation and analgosedation.

Abstract
PURPOSE This analysis was done to investigate the optimal regimen for fentanyl-based intravenous patient-controlled analgesia (IV-PCA) by finding a safe and effective background infusion rate and assessing the effect of adding adjuvant drugs to the PCA regimen. MATERIALS AND METHODS Background infusion rate of fentanyl, type of adjuvant analgesic and/or antiemetic that was added to the IV-PCA, and patients that required rescue analgesics and/or antiemetics were retrospectively reviewed in 1827 patients who underwent laparoscopic abdominal surgery at a single tertiary hospital. RESULTS Upon multivariate analysis, lower background infusion rates, younger age, and IV-PCA without adjuvant analgesics were identified as independent risk factors of rescue analgesic administration. Higher background infusion rates, female gender, and IV-PCA without additional 5HT₃ receptor blockers were identified as risk factors of rescue antiemetics administration. A background infusion rate of 0.38 μg/kg/hr [area under the curve (AUC) 0.638] or lower required rescue analgesics in general, whereas, addition of adjuvant analgesics decreased the rate to 0.37 μg/kg/hr (AUC 0.712) or lower. A background infusion rate of 0.36 μg/kg/hr (AUC 0.638) or higher was found to require rescue antiemetics in general, whereas, mixing antiemetics with IV-PCA increased the rate to 0.37 μg/kg/hr (AUC 0.651) or higher. CONCLUSION Background infusion rates of fentanyl between 0.12 and 0.67 μg/kg/hr may safely be used without any serious side effects for IV-PCA. In order to approach the most reasonable background infusion rate for effective analgesia without increasing postoperative nausea and vomiting, adding an adjuvant analgesic and an antiemetic should always be considered.

Abstract
INTRODUCTION Pain has been pointed out as one of the concerns of cardiac surgery patients. Acute pain management has been a challenge for health professionals and several regiments have been described. We designed this study to evaluate the effectiveness of pain control with patient-controlled analgesia (PCA) versus conventional nurse-controlled analgesia (NCA) during the postoperative period in the intensive care unit (ICU) after coronary artery bypass graft (CABG) surgery. METHODS In this randomized clinical trial, 80 elective CABG candidates were selected by convenience sampling. They were randomly allocated to two groups to receive either PCA or NCA. PCA plus continuous infusion of morphine started immediately after transferring the patients to the ICU. NCA was based on intravenous injections of morphine on demand. Pain was assessed using a verbal rating scale (VRS). Sedation level and morphine consumption were also evaluated from extubation until 48 hours after surgery. Data was analyzed using SPSS13. RESULTS VRS scores were higher in the NCA group compared to the PCA group [3.27 (1.17) vs. 0.75 (0.66); p < 0.001]. Morphine consumption was significantly higher in the PCA group compared to the NCA group [28.43 (7.15) mg vs. 8.37 (5.36) mg; p < 0.001]. PCA was safe and respiratory depression was not observed in any of the subjects. Mean sedation scores did not differ between the two groups. CONCLUSION PCA with background infusion of morphine increases morphine consumption and improves pain relief. It appears to be superior to NCA and can be recommended for patients after CABG surgery.

Abstract
One approach to clinical decision-making requires the integration of the best available research evidence with individual clinical expertise and patient values, and is known as evidence-based medicine (EBM). In clinical decision-making with the current best evidence, systematic reviews have an important role. This review article covers the basic principles of systematic reviews and meta-analyses, and their role in the process of evidence-based decision-making. The problems associated with traditional narrative reviews are discussed, as well as the way systematic reviews limit bias associated with the assembly, critical appraisal and synthesis of studies addressing specific clinical questions. The relevant steps in writing a systematic review from the formulation of an initial research question to sensitivity analyses in conjunction with the combined analysis of the pooled data are described. Important issues that need to be considered when appraising a systematic review or meta-analysis are outlined. Some of the terms that are used in the reporting of systematic reviews and meta-analyses, such as relative risk, confidence interval, Forest plot or L'Abbé plot, will be introduced and explained.

Abstract
Intravenous morphine is the treatment of choice for severe pain during vaso- occlusive crisis in sickle cell disease (SCD). However, side effects of morphine may hamper effective treatment, and high plasma levels of morphine are associated with severe complications such as acute chest syndrome. Furthermore, adequate dosing remains a problem since no objective measurement of pain severity exists and analgesia should be titrated upon the patient's reported pain. Patient-controlled analgesia (PCA) may therefore be an interesting alternative since patients can titrate the level of analgesia themselves. In this randomized controlled study, the efficacy of intravenous morphine administration with PCA was compared with continuous infusion (CI) of morphine in patients with SCD during vaso-occlusive crisis. Twenty five consecutive episodes of vaso-occlusive crisis in 19 patients with SCD were included in the study. Patients in the PCA-group had a markedly and significant lower mean and cumulative morphine consumption when compared with the patients in the CI-group (0.5 mg/hr versus 2.4 mg/hr (P < 0.001) and 33 mg versus 260 mg (P = 0.018, respectively). The mean daily pain scores were comparable (4.9 versus 5.3). The lower mean and cumulative morphine consumption in the PCA-group led to significant less nausea and constipation during treatment when compared with the CI-group (area under the curve, respectively, 11 versus 18 (P = 0.045) and 30 versus 45 (P = 0.021). Furthermore, a nonsignificant reduction in the duration of hospital admission of 3 days was observed in the PCA-group. PCA results in adequate pain relief at a much lower morphine consumption and should considered to be the first choice in morphine administration to sickle cell patients admitted with vaso-occlusive crisis.

Abstract
Patient-controlled analgesia (PCA) is a delivery system with which patients self-administer predetermined doses of analgesic medication to relieve their pain. Since its introduction in the early 1980s, the daily management of postoperative pain has been extensively optimised. The use of PCA in hospitals has been increasing because of its proven advantages over conventional intramuscular injections. These include improved pain relief, greater patient satisfaction, less sedation and fewer postoperative complications. All PCA modes contain the following variables: initial loading dose, demand dose, lockout interval, background infusion rate and 1-hour or 4-hour limits. Morphine is the most studied and most commonly used intravenous drug for PCA. In spite of the fact that it is the 'first choice' for PCA, other opioids have been successfully used for this option. The most observed adverse effects of opioid-based PCA are nausea and vomiting, pruritus, respiratory depression, sedation, confusion and urinary retention. Although intravenous PCA is the most studied route of PCA, alternative routes have extensively been described in the literature. PCA by means of peridural catheters and peripheral nerve catheters are the most studied. Recently, transdermal PCA has been described. The use of peripheral or neuraxial nerve blocks is recommended to avoid the so called opioid tolerance observed with the intravenous administration of opioids. Numerous studies have shown the superiority of epidural PCA to intravenous PCA. The beneficial postoperative effects of epidural analgesia are more apparent for high-risk patients or those undergoing higher risk procedures. PCA with peripheral nerve catheters results in increased postoperative analgesia and satisfaction for surgery on upper and lower extremities. Serious complications occur rarely with these catheters. With the introduction of an Acute Pain Service, management of postoperative pain can be improved. This will also help to minimise adverse effects related to PCA and to avoid lethal mishaps.

Abstract
OBJECTIVE To evaluate the effect of postoperative pain control in cardiac surgical patients on morbidity, mortality and other outcome measures. BACKGROUND New approaches in pain control have been introduced over the past decade. The impact of these interventions, either alone or in combination, on perioperative outcome was evaluated in cardiac surgical patients. METHODS We searched Medline for the period of 1980 to the present using the key terms analgesics, opioid, non-steroidal anti-inflammatory drugs, cardiac surgery, regional analgesia, spinal, epidural, fast-track cardiac anaesthesia, fast-track cardiac surgery, myocardial ischaemia, myocardial infarction, postoperative care, accelerated care programmes, postoperative complications, and we examined and discussed the articles that were identified to be included in this review. RESULTS Pain management in cardiac surgery is becoming more important with the establishment of minimally invasive direct coronary artery bypass surgery and fast-track management of conventional cardiac surgery patients. Advances have been made in this area and encompass specific techniques, such as central neuraxial blockade or selective nerve blocks, and drugs (opioids, sedative-hypnotics and non-steroidal anti-inflammatory drugs). Ideally, these therapies provide not only patient comfort but also mitigate untoward cardiovascular responses, pulmonary responses, and other inflammatory and secondary sympathetic responses. The introduction of these newer approaches to perioperative care has reduced morbidity, but not mortality, in cardiac surgical patients. CONCLUSIONS Understanding perioperative pathophysiology and implementation of care regimes to reduce the stress of cardiac surgery, will continue to accelerate rehabilitation associated with decreased hospitalization and increased satisfaction and safety after discharge. Reorganization of the perioperative team (anaesthesiologists, surgeons, nurses and physical therapists) will be essential to achieve successful fast-track cardiac surgical programmes. Developments and improvements of multimodal interventions within the context of 'fast-track' cardiac surgery programmes represents the major challenge for the medical professionals working to achieve a 'pain and risk free' perioperative course.
