Abstract
BACKGROUND AND OBJECTIVE High-dose opioid anaesthesia contributes to decreasing metabolic and hormonal stress responses in patients undergoing cardiac surgery. However, the increase in context-sensitive half-life of opioids given as a high-dose regimen can affect postoperative respiratory recovery. In contrast, remifentanil can be given in high doses without prolonging context-sensitive half-life due to its rapid metabolism. Therefore, we performed a prospective, randomized trial to compare anaesthesia consisting of propofol/remifentanil or propofol/sufentanil with regard to postoperative respiratory function and outcome. METHODS Patients undergoing coronary artery bypass grafting were randomized to a propofol/remifentanil (0.5-1.0 microg kg(-1) min(-1)) or propofol/sufentanil (30-40 ng kg(-1) min(-1)) based anaesthetic. Carbon dioxide response, forced expiratory volume in one second, vital capacity, and functional residual capacity were measured 1 day prior to the operation, 1 h before extubation, 1, 24 and 72 h after extubation. In addition, the incidence of atelectasis, pulmonary infiltrates, intensive care unit and postoperative length of stay were compared. Patients and physicians were blinded to the treatment group. RESULTS Twenty-five patients in each treatment group completed the study. There was no difference between patients of the treatment groups regarding demographics, risk- or pain scores. In all patients, carbon dioxide response, forced expiratory volume in one second, vital capacity and functional residual capacity were decreased postoperatively compared to baseline. Patients randomized to remifentanil had less depression of carbon dioxide response, less atelectasis and shorter postoperative length of stay (12 d vs. 10 d) than after sufentanil (P < 0.05). CONCLUSIONS Intraoperative use of high-dose remifentanil for coronary artery bypass grafting may be associated with improved recovery of pulmonary function and shorter postoperative hospital length of stay than sufentanil.

Abstract
STUDY DESIGN A prospective, randomized, controlled trial that compared the efficacy of different protocols of local tissue infiltration with bupivacaine or bupivacaine-methylprednisolone at the surgical site for pain relief after lumbar discectomy. OBJECTIVE To determine the efficacy of preemptive wound infiltration with bupivacaine and bupivacaine-methylprednisolone after lumbar discectomy. SUMMARY OF BACKGROUND DATA Patients usually have significant pain after lumbar discectomy. Wound infiltration with bupivacaine or bupivacaine-methylprednisolone is one method to address this. METHODS Seventy-five patients were randomly allocated to 5 equal groups as follows: Group I (n = 15) had the musculus multifidi near the operated level infiltrated with 30 mL 0.25% bupivacaine and 40 mg methylprednisolone just before wound closure; Group II (n = 15) had the same region infiltrated with 30 mL 0.25% bupivacaine alone before closure; Group III (n = 15) had this region infiltrated with 30 mL 0.25% bupivacaine and 40 mg methylprednisolone before the incision was made; in Group IV (n = 15), this region infiltrated with 30 mL 0.25% bupivacaine alone before incision; and Group C (controls, n = 15) had this region infiltrated with 30 mL 0.9% NaCl just before wound closure. Demographics, vital signs, postoperative pain scores, and morphine usage were recorded. RESULTS All 4 groups treated with bupivacaine or bupivacaine-methylprednisolone (by preemptive or preclosure wound infiltration) showed significantly better results than the control group for most parameters. The treated groups had lower parenteral opioid requirements after surgery, lower incidences of nausea, and shorter hospital stays. Further, the data indicate that, compared with infiltration of these drugs at wound closure, preemptive injection of bupivacaine or bupivacaine-methylprednisolone into muscle near the operative site provides more effective analgesia after lumbar discectomy. CONCLUSION In addition, our data suggest that preemptive infiltration of the wound site with bupivacaine alone provides similar pain control to preemptive infiltration of the wound site with bupivacaine and methylprednisolone combined.

Abstract
OBJECTIVE While narcotics remain the backbone of perioperative analgesia, the adjunctive role of other analgesics, including non-steroidal anti-inflammatory drugs (NSAIDs), is being recognized increasingly. This meta-analysis sought to determine whether adjunctive NSAIDs improve postoperative analgesia and reduce cumulative narcotic requirements. METHODS A comprehensive search was undertaken to identify all randomized trials, in cardiothoracic patients, of NSAIDs plus narcotics vs narcotics without NSAIDs. Medline, Cochrane Library, EMBASE, and abstract databases were searched up to September 2005. The primary outcome was visual analogue scale (VAS) pain score. Secondary outcomes included 24-hr cumulative morphine-equivalents, rescue medications required, mortality, myocardial infarction, atrial fibrillation, stroke, renal failure, hospital readmissions, and in-hospital costs. RESULTS Twenty randomized trials involving 1,065 patients were included. A significant reduction in 24-hr VAS pain score was found in patients receiving NSAIDs [weighted mean difference (WMD) -0.91 points, 95% confidence interval (CI) -1.48 to -0.34 points]. In addition, patients required significantly less morphine-equivalents in the first 24 hr (WMD -7.67 mg, 95% CI -8.97 to -6.38 mg). No significant difference was found with respect to mortality [odds ratio (OR) 0.19, 95% CI 0.01 to 4.22], myocardial infarction (OR 0.71, 95% CI 0.09 to 5.71), renal dysfunction (OR 0.95, 95% CI 0.37 to 2.46), or gastrointestinal bleeding (OR 0.96, 95% CI 0.13 to 7.09). CONCLUSION In patients less than 70 yr of age undergoing cardiothoracic surgery, the adjunctive use of NSAIDs with narcotic analgesia reduces 24-hr VAS pain score and narcotic requirements.

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.

Abstract
OBJECTIVE The United Kingdom Paediatric Intensive Care Society Sedation, Analgesia and Neuromuscular Blockade Working Group is a multi-disciplinary expert panel created to produce consensus guidelines on sedation and analgesia in critically ill children and forward knowledge in these areas. Sedation and analgesia are recognised as important areas of critical care practice and adult clinical practice guidelines in these fields remain amongst the most popular of those produced by the Society of Critical Care Medicine. However, similar clinical practice guidelines have not previously been produced for the critically ill paediatric patient. DESIGN A modified Delphi technique was used to allow the Working Group to anonymously consider draft recommendations in three Delphi rounds with predetermined levels of agreement. This process was supported by a total of four consensus conferences. Once consensus had been reached, a systematic review of the available literature was carried out. OUTCOME A set of consensus guidelines was produced including 20 key recommendations, 10 relating to the provision of analgesia and 10 relating to the sedation of critically ill children. An evaluation of the existing literature supporting these recommendations is provided. CONCLUSIONS Multi-disciplinary consensus guidelines for maintenance sedation and analgesia in critically ill children have been successfully produced and are supported by levels of evidence (excluding sedation and analgesia for procedures and excluding neonates). The working group has highlighted the paucity of high-quality evidence in these important clinical areas and this emphasises the need for further randomised clinical trials in this area.

Abstract
BACKGROUND Patient-controlled analgesia (PCA) has been advocated as superior to conventional nurse-controlled analgesia (NCA) with less risk to patients. This systematic review and meta-analysis sought to determine whether PCA improves clinical and resource outcomes when compared with NCA. METHODS A comprehensive search was undertaken to identify all randomized controlled trials of PCA vs NCA. Medline, Cochrane Library, Embase, and conference abstract databases were searched from the date of their inception to August 2005. The primary postoperative outcome was defined as mean visual analogue scale (VAS) scores. Secondary postoperative outcomes included cumulative morphine equivalents, intensive care unit (ICU) and hospital length of stay, postoperative nausea and vomiting, sedation, respiratory depression, and all-cause mortality. Odds ratios or weighted mean differences (WMD) and their 95% confidence intervals (CI) were calculated for discrete and continuous outcomes, respectively. RESULTS Ten randomized trials involving 666 patients were included. Compared to NCA, PCA significantly reduced VAS at 48 hr (WMD -0.73, 95% CI -1.19, -0.27), but not at 24 hr (WMD -0.19, 95% CI -0.61, 0.24). Cumulative morphine equivalents consumed were significantly increased at 24 hr (WMD 6.84 mg, 95% CI 0.97, 12.72 mg), and at 48 hr (WMD 10.46 mg 95% CI 2.02, 18.9 mg) for PCA compared with NCA. Ventilation times, length of ICU stay, length of hospital stay, patient satisfaction scores, sedation scores, and incidence of postoperative nausea and vomiting, respiratory depression, severe pain, discontinuations, and death were not significantly different between groups, but these outcomes were generally under-reported. CONCLUSIONS In postcardiac surgical patients, PCA increases cumulative 24 and 48 hr morphine consumption, and improves 48-hr VAS compared with NCA.

Abstract
BACKGROUND Parecoxib, a cyclo oxygenase-2 inhibiting non-steroidal anti-inflammatory drug, has been widely used for postoperative analgesia. Our aim was to quantify the benefit of a single dose after coronary artery bypass grafting. METHODS The investigation was carried out as a randomized double blind placebo controlled study. A single i.v. dose of parecoxib 40 mg or placebo was given at closure of sternotomy. No opioid other than morphine was given in the first 24 postoperative hours. Pain was assessed using both a Visual Analogue Score (1-10), and the amount of morphine used via a morphine patient controlled analgesia pump. Creatinine clearance was measured before and after operation from 24 h urine collections. After a global announcement by Pfizer that paracoxib was 'contraindicated in patients with ischaemic heart disease' further recruitment was suspended and the collected data from 40 patients were analysed. RESULTS Twenty-one patients received parecoxib and 19 received placebo. Amongst those who received parecoxib, there was a highly significant sparing of rescue medication before tracheal extubation (P=0.004) compared with placebo, and an overall 35% morphine sparing effect during the first 6 h post extubation after correction for the variability in extubation time (P=0.037). Respiration, as measured by arterial carbon dioxide tension at the time of extubation, was significantly better in the parecoxib group (P=0.045). Significantly more furosemide was given for postoperative oliguria in those patients who received parecoxib (P=0.036). After correcting for differences in diuretic usage and fluid balance, parecoxib was associated with a significant increase in plasma creatinine (P=0.041). CONCLUSION A single dose of parecoxib has a significant opioid sparing effect in the first 6 h after coronary artery bypass grafting which resulted in significantly improved ventilation with mild elevation of plasma creatinine within normal limits.

Abstract
Coronary artery bypass grafting was performed in a 58-year-old patient 3 years after right pneumonectomy for nonsmall cell lung cancer stage IIIa. The CT scan demonstrated a marked shift of the mediastinum into the right chest, but revealed a feasible access to the left coronary artery by median sternotomy. Pulmonary function was impaired. Off-pump coronary artery bypass grafting was performed to avoid cannulation under more difficult conditions and to prevent negative side effects of cardiopulmonary bypass to the pulmonary function. The postoperative recovery was uneventful. We discuss issues related to this special subgroup of patients.

Abstract
Remifentanil, a short-acting opioid, is commonly used in cardiac anesthesia. In this study we sought to demonstrate the feasibility of pain treatment and to determine the remifentanil dose necessary for adequate analgesia in tracheally extubated patients after cardiac surgery. Thirty patients undergoing elective cardiac surgery were included in this study. After surgery, the intraoperatively administered remifentanil was initially continued at 0.05 microg . kg(-1) . min(-1). Before tracheal extubation, a nonsteroidal antiinflammatory drug was administered and remifentanil was reduced to 0.035 microg . kg(-1) . min(-1). Pain assessment using a visual analog scale (VAS) was performed after tracheal extubation, in 2-min intervals for 10 min, every 10 min until the end of the first hour and every 30 min during the ensuing 5 h. A VAS score > or =30 or a respiratory rate <10 breaths/min was followed by an increase or decrease in the remifentanil dose by 0.005 microg . kg(-1) . min(-1), respectively. For rapid dose adaptation during the first 10 min, remifentanil was increased twice by 0.005 microg. kg(-1) . min(-1) and then 3 times by 0.01 microg . kg(-1) . min(-1). With a mean remifentanil dose of 0.051 microg . kg(-1) . min(-1) VAS decreased to 26 +/- 14 after 30 min. Sufficient analgesia was achieved with remifentanil doses ranging from 0.03 to 0.09 microg. kg(-1) . min(-1). A maximum mean remifentanil dose of 0.057microg. kg(-1) . min(-1) was reached after 4 h. The combination of remifentanil with a nonsteroidal antiinflammatory drug provided adequate analgesia in 73% of patients 30 min after tracheal extubation. Rapid dose titration was necessary during the first 10 min in 50% of patients. Increasing the initial remifentanil dose could shorten the titration period but may be associated with respiratory complications.

Abstract
BACKGROUND There are two common techniques for postoperative pain control after intra-abdominal surgery: patient-controlled analgesia (PCA) with intravenous opioids and continuous epidural analgesia (CEA). It is uncertain which method has better pain control and fewer adverse effects. OBJECTIVES The objective of this review was to compare PCA opioid therapy with CEA for pain control after intra-abdominal surgery in terms of analgesic efficacy, side effects, patient satisfaction and surgical outcome by meta-analysis of the relevant trials. SEARCH STRATEGY We searched CENTRAL (The Cochrane Library Issue 4, 2002), MEDLINE (January 1966 to October 2002), EMBASE (January 1988 to October 2002), and reference lists of articles. We also contacted researchers in the field. SELECTION CRITERIA Randomized controlled trials of adult patients after intra-abdominal surgery comparing the effect of two pain control regimens in terms of analgesic efficacy and side effects. In the patient-controlled analgesia (PCA) group the patient should be able to operate the device himself. In the continuous epidural analgesia group there was no PCA device. DATA COLLECTION AND ANALYSIS Two reviewers independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Nine studies involving 711 participants were included. The PCA group had a higher pain visual analogue scale than the CEA group during 6, 24 and 72 hour periods. The weighted mean difference and 95% confidence interval of resting pain was 1.74 (95% CI 1.30 to 2.19), 0.99 (95% CI 0.65 to 1.33), and 0.63 (95% CI 0.24 to 1.01), respectively. The length of hospital stay and other adverse effects were not statistically different except that the incidence of pruritus was lower in the PCA group, odds ratio of 0.27 (95% CI 0.11 to 0.64). AUTHORS' CONCLUSIONS CEA is superior to opioid PCA in relieving postoperative pain for up to 72 hours in patients undergoing intra-abdominal surgery, but it is associated with a higher incidence of pruritus. There is insufficient evidence to draw comparisons about the other advantages and disadvantages of these two methods of pain relief.

Abstract
OBJECTIVE The purpose of this study was to compare the analgesic effects of remifentanil with 2 other opioid agents, morphine and fentanyl, after cardiac surgery. DESIGN Prospective, randomized, and double-blinded study. SETTINGS This study was performed at Uludag University hospital. PARTICIPANTS Seventy-five patients undergoing off-pump coronary artery bypass surgery were included in the study. INTERVENTIONS Anesthesia was standardized. Cases were randomized into 3 groups consisting of 25 patients in each. Groups M, F, and R were given morphine HCl (1 mg/mL) with an infusion rate of 0.3 mg/h and 1-mg bolus doses; fentanyl (50 microg/mL) with an infusion rate of 1 microg/kg/h and 10-microg bolus; and, remifentanil (50 microg/mL) with an infusion rate of 0.05 microg/kg/min and 0.5-microg/kg bolus, respectively. Continuous infusion was started immediately after the completion of the surgery. MEASUREMENTS AND MAIN RESULTS Pain was assessed by using a visual analog scale (0-10), and sedation was assessed with the Ramsey sedation score (1-6) 30 minutes, 1, 2, 4, 12, and 24 hours after extubation. The number of boluses and demands, time to extubation, and side effects were analyzed. Visual analog scale, sedation scores, and mean extubation times were similar in all groups. Total number of boluses and demands were statistically more in the remifentanil group. Regarding the side effects, nausea and vomiting was higher in group M (p < 0.05), whereas itching was prominent in group F (p < 0.05). CONCLUSIONS Despite the different durations of these 3 opioid agents, the infusion dose of remifentanil was as effective as morphine and fentanyl after OPCAB surgery with fewer side effects.

Abstract
Postoperative pulmonary complications are the most frequent and significant contributor to morbidity, mortality, and costs associated with hospitalization. Interestingly, despite the prevalence of these complications in cardiac surgical patients, recognition, diagnosis, and management of this problem vary widely. In addition, little information is available on the continuum between routine postoperative pulmonary dysfunction and postoperative pulmonary complications. The course of events from pulmonary dysfunction associated with surgery to discharge from the hospital in cardiac patients is largely unexplored. In the absence of evidence-based practice guidelines for the care of cardiac surgical patients with postoperative pulmonary dysfunction, an understanding of the pathophysiological basis of the development of postoperative pulmonary complications is fundamental to enable clinicians to assess the value of current management interventions. Previous research on postoperative pulmonary dysfunction in adults undergoing cardiac surgery is reviewed, with an emphasis on the pathogenesis of this problem, implications for clinical nursing practice, and possibilities for future research.

Abstract
PURPOSE We compared the efficacy of patient-controlled analgesia (PCA), with or without a background infusion of morphine, on postoperative pain relief in patients extubated in the operating room after coronary artery bypass grafting (CABG) surgery. METHODS With Faculty Ethics approval, 60 consenting adults undergoing elective coronary artery surgery were randomly assigned to receive either morphine PCA alone (group PCA-A, n = 30) or morphine PCA plus a background infusion (group PCA-B, n = 30) for 24 hr postoperatively. Pain scores with verbal rating scale (VRS; from 0 to 10) at rest, sedation scores, morphine consumption and delivery/demand ratios were assessed at zero, one, two, four, six, 12 and 24 hr after surgery. Hemodynamic variables and arterial blood gases were also recorded in the same periods. RESULTS Sedation scores in the two groups were similar. At all study periods after the first postoperative hour, VRS remained below 5 in both groups. Pain scores were significantly lower in the background infusion group, which also had greater cumulative morphine consumption (61.7 +/- 10.9 mg vs 38.5 +/- 16.2 mg). There were no episodes of hypoxemia or hypertension. CONCLUSION Morphine PCA effectively controlled postoperative pain after cardiac surgery. The addition of a background infusion of morphine enhanced analgesia and increased morphine consumption.

Abstract
Pain management is an essential component of quality care delivery for the critically ill patient. Because outcomes are difficult to predict in the intensive care unit (ICU), high-quality pain management and palliative therapy should be a goal for every patient. For those patients actively dying, palliation may be among the main benefits offered by the health care team. Appropriate palliation of pain begins with the use of effective strategies for recognizing, evaluating,and monitoring pain. Skill in pain management requires knowledge of both pharmacologic and nonpharmacologic therapies. This article focuses on expertise in the use of opiates to facilitate confident and appropriate pain therapy. To optimize palliative therapy, symptoms are best addressed by interdisciplinary care teams guided by models that acknowledge a continuum of curative therapies and palliative care.

Abstract
• Background Acute pain is common after cardiac surgery and can keep patients from participating in activities that prevent postoperative complications. Accurate assessment and understanding of pain are vital for providing satisfactory pain control and optimizing recovery.• Objectives To describe pain levels for 5 activities expected of patients after cardiac surgery on postoperative days 1 to 6 and changes in pain levels after chest tube removal and extubation.• Methods Adults who underwent cardiac surgery were asked to rate the pain associated with various types of activities on postoperative days 1 to 6. Pain levels were compared by postoperative day, activity, and type of cardiac surgery. Pain scores before and after chest tube removal and extubation also were analyzed.• Results Pain scores were higher on earlier postoperative days. The order of overall pain scores among activities (P < .01) from highest to lowest was coughing, moving or turning in bed, getting up, deep breathing or using the incentive spirometer, and resting. Changes in pain reported with coughing (P=.03) and deep breathing or using the incentive spirometer (P = .005) differed significantly over time between surgery groups. After chest tubes were discontinued, patients had lower pain levels at rest (P = .01), with coughing (P=.05), and when getting up (P=.03).• Conclusions Pain relief is an important outcome of care. A comprehensive, individualized assessment of pain that incorporates activity levels is necessary to promote satisfactory management of pain.

Abstract
OBJECTIVE We sought to determine whether a continuous regional infusion of a local anesthetic delivered to the operative site would result in decreased levels of postoperative pain and narcotic requirements for patients who undergo a standard median sternotomy for cardiac surgery. METHODS A double-blind, randomized, controlled trial was conducted at a single center. Patients who were undergoing elective coronary artery bypass graft surgery alone or combined with laser transmyocardial revascularization received bilateral intercostal nerve blocks with either ropivacaine or saline. At wound closure, 2 catheters with multiple side openings were inserted percutaneously and placed directly over the sternum. The same agent (ropivacaine vs saline) was then administered as a continuous regional infusion for 48 hours through an elastomeric pump. Requirements for postoperative systemic narcotic analgesics and pain assessment scores were recorded for 72 hours after the operation. Secondary outcome measures were hospital length of stay and pulmonary function test results. Pain scores and narcotic use on the second postoperative day were also compared to avoid the confounding influence of anesthesia administered at the time of the operation. RESULTS The total amount of narcotic analgesia required by the ropivacaine group was significantly less than that of the control group (47.3 vs 78.7 mg, respectively; P =.038). The ropivacaine group required less narcotics on postoperative day 2 as well (15.5 vs 29.4 mg, P =.025). The mean overall pain scores for the ropivacaine group were significantly less than the mean overall scores for the normal saline group (1.6 vs 2.6, respectively; P =.005). Patients receiving ropivacaine had a mean length of stay of 5.2 days compared with 8.2 days for patients in the normal saline group (P =.001). Excluding the data from outliers (length of stay = 39 days), the normal saline group mean length of stay was 6.3 days (P <.01). There was no difference in assessment of pulmonary function. CONCLUSION Continuous delivery of local anesthetics significantly improved postoperative pain control while decreasing the amount of narcotic analgesia required in patients who underwent standard median sternotomy. There was also a significant decrease in hospital length of stay, which is likely to result in significant cost reductions.

Abstract
OBJECTIVE Inhibition of cyclooxygenase 2 provides analgesia in ambulatory patients. We prospectively evaluated the safety and efficacy of a newly introduced cyclooxygenase 2 inhibitor in patients undergoing coronary artery bypass grafting surgery through a median sternotomy in a randomized clinical trial. METHODS A total of 462 patients with New York Heart Association classes I to III who were less than 77 years of age and were from 58 institutions in the United States, Canada, Germany, and the United Kingdom participated in this multicenter, phase III, placebo-controlled, double-blind, randomized, parallel-group trial. Patients were allocated at a ratio of 2:1 to parecoxib/valdecoxib or standard care (control) groups, respectively. Intravenous study drug (40 mg) was administered within 30 minutes after extubation and every 12 hours for a minimum of 3 days. Subsequently, oral treatment at a dose of 40 mg every 12 hours was initiated and administered for a combined total of 14 days. Patient-controlled analgesia with morphine, oral opioids, or acetaminophen was available as required. Assessment of the analgesic efficacy of the study drug was primarily based on morphine and morphine equivalent use. Additional efficacy evaluations included daily pain intensity, patient and physician global evaluation of study medication, and pain effect on quality of life. Clinical adverse events were assessed by the principal investigator at each site from the time of the first dose through the 30-day postdosing period. RESULTS Patients in the parecoxib/valdecoxib group received significantly less morphine or morphine equivalents than patients in the control group during the 0- to 24-hour (P =.009), 24- to 48-hour (P =.017), 72- to 96-hour (P =.002), 96- to 120-hour (P =.004), and 120- to 144-hour (P =.037) periods. Both patients (P <.001) and physicians (P <.001) evaluated the study medication as significantly better than control therapy. The modified Brief Pain Inventory questionnaire used in the oral dosing period detected significant improvements in the parecoxib/valdecoxib treatment group in 6 of 8 domains tested (eg, current pain, worst pain, and mood) beginning on day 4 and continuing for at least 4 days. Although there were no differences between the groups in overall adverse events, serious adverse events occurred twice as frequently in parecoxib/valdecoxib-treated patients (19.0%, 59/311 patients) than in control patients (9.9%, 15/151 patients; P =.015). Regarding individual serious adverse events, a greater incidence in sternal wound infection was found in the parecoxib/valdecoxib patients (10 [3.2%]) versus control patients (0 [0%]) (P =.035). The incidences of other individual serious adverse events, including cerebrovascular complications, myocardial infarction, and renal dysfunction, were proportionally greater but not significantly different between the groups. CONCLUSIONS In patients undergoing coronary artery bypass grafting surgery, the cyclooxygenase 2 inhibitor combination, parecoxib/valdecoxib, was effective for postoperative analgesia. However, the 14-day treatment regimen also was associated with an increased incidence of serious adverse events overall and sternal wound infections in particular. Therefore our study raises important concerns requiring their comprehensive evaluation in a large-scale trial before these cyclooxygenase 2 inhibitors are used in patients undergoing coronary artery bypass grafting surgery.

Abstract
OBJECTIVE The purpose of this study was to determine whether postoperative pain intensity differs between elderly abdominal surgery patients in whom postoperative pulmonary complications (PPC) develop and those in whom they do not. METHODS The exploratory secondary analysis of data from a prospective study of risk factors for PPC had a convenience sample of 86 patients (> or =60 years old) after abdominal surgery at 3 Midwestern hospitals. Daily measurements from postoperative day (POD) 1 to 6 included: pain (rated 0 to 10) at rest, with coughing, deep breathing, movement and walking, and frequency of ambulation. RESULTS Sixteen subjects (18.6%) had a PPC develop. Subjects with PPCs had higher mean pain intensities on all measures on each POD than those without. Those with PPCs had significantly higher pain intensities at rest on POD4 (P = .010), with deep breathing on POD2 (P = .015), POD4 (P = .009), POD5 (P = .006), and POD6 (P = .009), were up to a chair significantly fewer times on POD2 (P = .043), and walked significantly fewer times on POD5 (P = .002) and POD6 (P = .000) than those without PPCs. Length of stay for those with PPCs (mean, 17.9 days; standard deviation, 15.9 days; median, 10.0 days) was significantly longer than for those without PPCs (mean, 8.5 days; standard deviation, 4.8 days; median, 7.0 days; P = .000). CONCLUSION Results provide support for viewing pain as a factor that contributes to the development of PPCs among the elderly population after abdominal surgery. Therefore, nursing interventions of pain assessment and management, deep breathing, and ambulation may influence the incidence of this outcome.

Abstract
Evaluation of analgesic agents is multifactorial. The authors know of no direct comparisons among the choices in analgesic agents that suggest one therapy over another in global outcomes such as mortality or morbidity. Therefore, until further outcome differentiation between agents is proved, understanding the primary difference of delivery routes, mechanisms of action, pharmacokinetics, and adverse effects serves as the best guide for selecting the appropriate agent for each patient.

Abstract
Anxiety, agitation, delirium, and pain are common findings in the ICU. These unhealthy states may lead to increased irritability, discomfort, hypertension, tachycardia, cardiac ischemia, harmful motor activity, and psychologic disquiet for the patient. The appropriate treatment of these conditions may lead to decreased morbidity and mortality in the critically ill patient. Unfortunately, the management of anxiety, agitation, delirium, and pain in the intensive care unit is not ideal. Many patients interviewed after an ICU stay rate their pain control as poor and their memories of their stay as unpleasant. Furthermore, many caregivers lack sufficient understanding of the appropriate or indicated uses of drugs to allay patients' fears and pain. The use of suitable protocols for the proper titration of sedation of mechanically ventilated patients and monitoring of the level of sedation in ventilated patients may decrease the amount of time that patients are ventilated and may alleviate some of the emotional stresses of recall of painful procedures or uncomfortable mechanical ventilation. Future research into protocols for the care of the critically ill patient can enhance the overall well-being of these patients.

Abstract
BACKGROUND The usefulness of intravenous patient-controlled analgesia (PCA) with opioids for postoperative analgesia is not well defined. METHODS We systematically searched (MEDLINE, EMBASE, Cochrane Library, bibliographies, any language, to January 2000) for randomised trials comparing opioid-based PCA with the same opioid given intramuscularly, intravenously, or subcutaneously. Weighted mean differences (WMD) for continuous data, relative risks (RR) and numbers-needed-to-treat (NNT) for dichotomous data were calculated with 95% confidence intervals (CI) using fixed and random effects models. RESULTS Data from 32 trials were analysed: 22 (1139 patients) were with morphine, five (682) with pethidine, three (184) with piritramide, one (47) with nalbuphine and one (20) with tramadol. In three morphine and one pethidine trial (352 patients), more patients preferred PCA (89.7% vs. 65.8%, RR 1.41 (95%CI 1.11 to 1.80), NNT 4.2). Combined dichotomous data on pain intensity and relief, and the need for rescue analgesics from eight morphine, one pethidine, one piritramide, and one nalbuphine trial (691 patients), were in favour of PCA (RR 1.22 (1.00 to 1.50), NNT 8). In two morphine trials (152), pulmonary complications were more frequently prevented with PCA (100% vs. 93.3%, RR 1.07 (1.01 to 1.14), NNT 15). There was equivalence for cumulative opioid consumption, pain scores, duration of hospital stay, and opioid-related adverse effects. CONCLUSION These trials provide some evidence that in the postoperative pain setting, PCA with opioids, compared with conventional opioid treatment, improve analgesia and decrease the risk of pulmonary complications, and that patients prefer them.

Abstract
Nosocomial pneumonia (NP) is well documented as the second most common nosocomial infection. It is now more common in surgical patients than surgical-site or wound infection. Healthcare implications of NP include not only increased patient morbidity and mortality, but also increased use of healthcare resources. The advanced practice nurse plays an integral role in the prevention and minimization of NP across healthcare settings. This article focuses on postoperative NP after abdominal, cardiac, or thoracic surgery in the non-mechanically ventilated patient and discusses the diagnostic assessment, risk factors, and potential nurse-sensitive interventions to prevent or minimize this complication. Ideas for potential nursing research related to these risk factors are described.
