Abstract
BACKGROUND Patient-controlled analgesia (PCA) is a well-established form of postoperative pain management. One form of administration is patient-controlled regional analgesia (PCRA), where local anesthetics are administered via peripheral regional catheters; however, a prerequisite is that the patients are instructed on its use. A multitude of sources recommend that these instructions are given before surgery as preoperative training on pain management procedures has been shown to significantly reduce patients' postoperative pain and increase their well-being. OBJECTIVE The aim was to assess the effect of guideline-assisted preoperative patient education for PCRA on postoperative pain in patients undergoing orthopedic surgery compared to unstructured postoperative standard instructions. MATERIAL AND METHODS A controlled study with two randomized samples and a postinterventional survey was conducted. Overall, 73 patients with PCRA catheters for orthopedic surgery were enrolled in the study. The 37 participants in the interventional group (IG) received guideline-based structured instructions on PCRA use as well as a handout immediately before the surgical intervention. The 36 patients in the control group (CG) received postoperative instructions in the anesthesia recovery room. Pain was documented according to the numerical rating scale (NRS) at 2h (t1), 6h (t2), and 24h (t3) after surgery. RESULTS There were no statistically significant differences in the average pain scores between the two groups; however, there were lower mean pain scores in the IG at t1 and t3. CONCLUSION A significant reduction of pain in the IG could not be shown. Further studies concerning this topic with larger samples and adapted points in time are recommended.

Abstract
BACKGROUND In a review and meta-analysis conducted in 1993, psychological preparation was found to be beneficial for a range of outcome variables including pain, behavioural recovery, length of stay and negative affect. Since this review, more detailed bibliographic searching has become possible, additional studies testing psychological preparation for surgery have been completed and hospital procedures have changed. The present review examines whether psychological preparation (procedural information, sensory information, cognitive intervention, relaxation, hypnosis and emotion-focused intervention) has impact on the outcomes of postoperative pain, behavioural recovery, length of stay and negative affect. OBJECTIVES To review the effects of psychological preparation on postoperative outcomes in adults undergoing elective surgery under general anaesthetic. SEARCH METHODS We searched the Cochrane Register of Controlled Trials (CENTRAL 2014, Issue 5), MEDLINE (OVID SP) (1950 to May 2014), EMBASE (OVID SP) (1982 to May 2014), PsycINFO (OVID SP) (1982 to May 2014), CINAHL (EBESCOhost) (1980 to May 2014), Dissertation Abstracts (to May 2014) and Web of Science (1946 to May 2014). We searched reference lists of relevant studies and contacted authors to identify unpublished studies. We reran the searches in July 2015 and placed the 38 studies of interest in the `awaiting classification' section of this review. SELECTION CRITERIA We included randomized controlled trials of adult participants (aged 16 or older) undergoing elective surgery under general anaesthesia. We excluded studies focusing on patient groups with clinically diagnosed psychological morbidity. We did not limit the search by language or publication status. We included studies testing a preoperative psychological intervention that included at least one of these seven techniques: procedural information; sensory information; behavioural instruction; cognitive intervention; relaxation techniques; hypnosis; emotion-focused intervention. We included studies that examined any one of our postoperative outcome measures (pain, behavioural recovery, length of stay, negative affect) within one month post-surgery. DATA COLLECTION AND ANALYSIS One author checked titles and abstracts to exclude obviously irrelevant studies. We obtained full reports of apparently relevant studies; two authors fully screened these. Two authors independently extracted data and resolved discrepancies by discussion.Where possible we used random-effects meta-analyses to combine the results from individual studies. For length of stay we pooled mean differences. For pain and negative affect we used a standardized effect size (the standardized mean difference (SMD), or Hedges' g) to combine data from different outcome measures. If data were not available in a form suitable for meta-analysis we performed a narrative review. MAIN RESULTS Searches identified 5116 unique papers; we retrieved 827 for full screening. In this review, we included 105 studies from 115 papers, in which 10,302 participants were randomized. Mainly as a result of updating the search in July 2015, 38 papers are awaiting classification. Sixty-one of the 105 studies measured the outcome pain, 14 behavioural recovery, 58 length of stay and 49 negative affect. Participants underwent a wide range of surgical procedures, and a range of psychological components were used in interventions, frequently in combination. In the 105 studies, appropriate data were provided for the meta-analysis of 38 studies measuring the outcome postoperative pain (2713 participants), 36 for length of stay (3313 participants) and 31 for negative affect (2496 participants). We narratively reviewed the remaining studies (including the 14 studies with 1441 participants addressing behavioural recovery). When pooling the results for all types of intervention there was low quality evidence that psychological preparation techniques were associated with lower postoperative pain (SMD -0.20, 95% confidence interval (CI) -0.35 to -0.06), length of stay (mean difference -0.52 days, 95% CI -0.82 to -0.22) and negative affect (SMD -0.35, 95% CI -0.54 to -0.16) compared with controls. Results tended to be similar for all categories of intervention, although there was no evidence that behavioural instruction reduced the outcome pain. However, caution must be exercised when interpreting the results because of heterogeneity in the types of surgery, interventions and outcomes. Narratively reviewed evidence for the outcome behavioural recovery provided very low quality evidence that psychological preparation, in particular behavioural instruction, may have potential to improve behavioural recovery outcomes, but no clear conclusions could be reached.Generally, the evidence suffered from poor reporting, meaning that few studies could be classified as having low risk of bias. Overall,we rated the quality of evidence for each outcome as 'low' because of the high level of heterogeneity in meta-analysed studies and the unclear risk of bias. In addition, for the outcome behavioural recovery, too few studies used robust measures and reported suitable data for meta-analysis, so we rated the quality of evidence as `very low'. AUTHORS' CONCLUSIONS The evidence suggested that psychological preparation may be beneficial for the outcomes postoperative pain, behavioural recovery, negative affect and length of stay, and is unlikely to be harmful. However, at present, the strength of evidence is insufficient to reach firm conclusions on the role of psychological preparation for surgery. Further analyses are needed to explore the heterogeneity in the data, to identify more specifically when intervention techniques are of benefit. As the current evidence quality is low or very low, there is a need for well-conducted and clearly reported research.

Abstract
OBJECTIVES The purpose of this study was to see if an instructional card, attached to the PCA machine following total hip arthroplasty describing proper use of the device, would positively affect subjects' understanding of device usage, pain scores, pain medication consumption and satisfaction. METHODS Eighty adults undergoing total hip replacements who had been prescribed PCA were randomized into two study groups. Forty participants received the standard post-operative instruction on PCA device usage at our institution. The other 40 participants received the standard of care in addition to being given a typed instructional card immediately post-operatively, describing proper PCA device use. This card was attached to the PCA device during their recovery period. On post-operative day one, each patient completed a questionnaire on PCA usage, pain scores and satisfaction scores. RESULTS The pain scores in the Instructional Card group were significantly lower than the Control group (p = 0.024). Subjects' understanding of PCA usage was also improved in the Instructional Card group for six of the seven questions asked. CONCLUSION The findings from this study strongly support that postoperative patient information on proper PCA use by means of an instructional card improves pain control and hence the overall recovery for patients undergoing surgery. In addition, through improved understanding it adds an important safety feature in that patients and potentially their family members and/or friends may refrain from PCA-by-proxy. This article demonstrates that the simple intervention of adding an instructional card to a PCA machine is an effective method to improve patients' knowledge as well as pain control and potentially increase the safety of the device use.

Abstract
PURPOSE This study was to investigate the effects of the provision of concrete information about patient-controlled analgesia (PCA) in hysterectomy patients. METHODS Study design was a nonequivalent control group non-synchronized pre- and post-test design. Sixty subjects participated were assigned to experimental group (30 patients) or control group (30 patients) at one university hospital. Concrete information about PCA was composed of three sections: explanation with a leaflet, practice of using PCA, and question and answer session. RESULTS The experimental group who received concrete information about PCA before surgery had statistically higher knowledge level about PCA, more positive attitude toward pain control analgesia, a lower pain score, and a higher satisfaction level of the use of PCA post-surgery compared to the control group who received general information before surgery. CONCLUSION Provision of concrete information about PCA was an effective nursing intervention that reduced post-operative pain for patients and increased their satisfaction with using PCA. It is recommended that concrete information about PCA be provided by nurses to promote the use of PCA and consequently reduce patient's pain post-surgery.

Abstract
Anesthesiologists play a critical role in facilitating a positive perioperative experience and early recovery for patients. Depending on the kind of procedure or surgery, a wide variety of agents and techniques are currently available to anesthesiologists to administer safe and efficacious anesthesia. Notably, the fast-track or ambulatory surgery environment requires the use of agents that enable rapid induction, maintenance, and emergence combined with minimal adverse effects. Short-acting opioids demonstrate a safe and rapid onset/offset of effect; that short effect is both predictable and precise. It also ensures easier titration and reduced or rapidly reversed side effects. Due to their distinct pharmacokinetic and pharmacodynamic properties, and, in one case, rapid extra-hepatic clearance of remifentanil, these agents have several applications in general anesthesia.

Abstract
Background Preoperative education is a common feature of the preoperative preparation for many surgical procedures. It is anticipated that this education will result in beneficial outcomes for the patient. Many studies have evaluated the effectiveness of different formats used to deliver the information, and the effect of this information on a variety of outcomes. While there has been substantial research and several meta-analyses undertaken on different aspects of preoperative education, there has been no previous attempt to summarise this body of research to evaluate its impact on knowledge and understanding of patients. Objective The objective of this review was to present the best available evidence related to knowledge retention and/or correct performance of postoperative activities after preoperative patient education. Review method This review considered all studies that included adults in a hospital setting, either as inpatients or same day surgical patients, and who received some form of information and/or instruction before an operative procedure. Interventions were the methods of preoperative patient education, instruction or teaching, and included evaluations of the effectiveness of different presentations such as: • written information; • audio-visual aids; • computer-assisted instruction; • learning packages in either group or individual formats, at either pre-admission or post-admission. The primary outcomes were those associated with the understanding of the information related to the operative or postoperative period that were provided in the intervention and included: 1 increased knowledge; 2 ability to perform postoperative activities; 3 time to teach skills. This review considered randomised controlled trials that evaluated forms of preoperative patient education and their effect on patient understanding, knowledge and ability to perform postoperative activities. Results The findings of this review support the use of pamphlets to inform patients and to improve their skills. The role of videos as a preoperative instruction tool has not been rigorously evaluated. However, existing studies support the use of preoperative videos to improve patient knowledge and skill. The data suggest that the instructional method, the act of educating a patient by delivering directions for actions or behaviour is useful for improving patients' knowledge of their treatment and their ability to perform and comply with required exercises. However, instruction is likely to be more effective if provided before admission. If teaching is to be done after admission, using a group format has been shown to be equally as effective as individual instruction. Conclusions Although numerous studies have been performed on many aspects of preoperative education, little high-quality research has assessed the effectiveness of this information on patient knowledge and ability to perform specific skills such as exercises. Further research is required to examine: (i) the effectiveness of pamphlets and other written material for people with English as a second language or limited literary skills; (ii) the accuracy of information provided in preoperative pamphlets; (iii) the effectiveness of pamphlets on general populations; (iv) the role of videos and learning packages; (v) the effectiveness of preoperative instruction; and (vi) the changes in patient misconceptions with the provision of preoperative information.

Abstract
Prevention of preoperative anxiety with anxiolytic premedication is associated with improved preoperative outcomes in surgical patients. The objective of the authors' study was to evaluate the percentage of surgical patients that are prescribed premedication for preoperative anxiety before their anticipated surgical procedure. A prospective study was carried out by theatre nursing staff in the theatre reception bay of a university teaching hospital. A questionnaire was designed to record the number of patients that described symptoms consistent with preoperative anxiety. The number of patients that had been offered anxiolytic premedication for preoperative anxiety was also recorded. Consent was obtained from 115 consecutive surgical patients (male, n=52; female, n=63). Of these, 66% (n=76) reported anxiety before their surgical procedure (male: n=27, female: n=49). Premedication with a low-dose benzodiazepine was prescribed by an anaesthetist in 4% of cases (n=5). Patients that received premedication preoperatively reported effective relief of their anxiety symptoms This study demonstrates that preoperative patient anxiety is highly prevalent. The authors' findings suggest that premedication with anxiolytic pharmacological therapy may be an underused therapeutic resource for managing preoperative patient anxiety.

Abstract
Orthopaedic and traumatized patients often suffer from severe pain after surgery or trauma. Their early recovery also depends on an efficient acute pain relief based on a combination of systemic medication, local drug application and physical therapy. In 2007, new guidelines for the treatment of perioperative and traumatic pain were published. Based on these guidelines standard operating procedures for each hospital should be developed and implemented. Courses on analgesic concepts should be offered regularly for the involved staff. It is helpful to establish an acute pain service for daily rounds and documentation. The individual patient should be informed about his specific acute pain therapy before the operation. Pain scores should be frequently documented by the patient.

Abstract
BACKGROUND AND OBJECTIVES Because patients who are to undergo surgery must give their consent to planned postoperative care, clear and complete information on postoperative pain management should be given. The aim of this quality-of-care study was to evaluate by inquiry the impact of written information describing postoperative pain management on the quality and type of information retained, and patient participation in discussing and agreeing to the postoperative pain management programme during the presurgical anaesthesiology consultation. METHODS Prospective before and after interventional surveys, each lasting 3 weeks and conducted at a 6-month interval (time required to prepare the written information), used a standardized anonymous questionnaire given to patients after the anaesthesiology consultation. Questions requiring a 'yes' or 'no' response assessed the quality of information and what information was retained by the patient, the extent of the patient's interaction during the discussion with the anaesthesiologist and his/her agreement with the postoperative pain management programme. RESULTS Among the 180 before-group patients included, 16.7% reported receiving verbal information during the anaesthesiology consultation, none retained all seven principal side-effects of morphine, 14.4% considered the information to be thorough, 20.6% understood it, 16.7% claimed that it had helped them participate in the discussion and 14.4% concurred with the postoperative pain management programme. Compared to the before inquiry, significantly higher percentages of the 107 after-group patients (given written information before the anaesthesiology consultation) responded as having received verbal information during the anaesthesiology consultation (57.0%), retained morphine's main side-effects (12.1%), deemed the information thorough (58.9%) and understandable (53.3%), had participated in the discussion (47.7%) and agreed with the postoperative pain management programme (51.4%). CONCLUSION Written information on postoperative pain management distributed before the presurgical anaesthesiology consultation improved the quality of information retained, facilitated discussion with the anaesthesiologist and patient agreement with the postoperative pain management programme.

Abstract
BACKGROUND Provision of sufficient perioperative pain therapy is an obligation in the clinical management of patients suffering from pain. The implementation of a standardized pain management concept was planned to be introduced in the clinical routine. The results of three hospitals are shown. MATERIAL AND METHODS The concept included tools which gave information about legal aspects and basic fundamentals of pain relief, management modules regarding agreements on the implementation of perioperative pain therapy, instruments to measure pain intensity, assigning accountability and documentation modules. Questionnaires were carried out according to Picker. RESULTS The project revealed that, according to the Picker questionnaire, about 50% of the patients treated in the hospitals had pain, 30-40% still had intensive pain during the stay in hospital and 90% of the patients received pain relief medication within 10 min of the request. More than 78% of the patients thought the hospital staff did their best to relieve the pain and over 92% found the pain treatment adequate. CONCLUSION It was possible to implement a standardized perioperative pain therapy concept in three hospitals of a consortium. Whether an adequate pain relief can be improved with the help of standard measurements and documentation, could not be evaluated in this study.

Abstract
Patient-controlled analgesia was introduced as a technique that would allow greater flexibility in opioid delivery for the management of acute pain. However, so far, any benefit compared with conventional methods of pain relief appears to be small. This article reviews some of the factors that could limit the usefulness of intravenous patient-controlled analgesia in the clinical setting and what strategies might allow patient-controlled analgesia to become more effective.

Abstract
Patient-controlled analgesia (PCA) has become the gold standard for acute pain management since it was first introduced 20 years ago, and its merits have been discussed in quite a large number of publications. This review summarizes the more recent developments, such as new application devices and strategies, including intranasal, spinal, and regional PCA; patient-controlled sedation; experience with children and elderly people; and some data from chronic pain situations. Analyzing PCA literature from 2001 onwards confirms the author's long belief that the PCA principle ("WYNIWYG": what you need is what you get) was the most important aspect of a patient-controlled strategy, more or less independent of the type of drug or machine. Discovering this principle has changed the understanding of pain and suffering.

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
Institutions with quality management programs need to evaluate the quality of perioperative pain management as well as other aspects of the health service. With the development of anesthesia-based pain services, improvement in this field has been reported. In this prospective study performed in a university hospital, we used a Postoperative Pain Therapy Assessment Questionnaire to quantify the effectiveness of pain therapy and factors affecting the degree of satisfaction and also to pinpoint areas that need improvement. A total of 915 patients who received patient-controlled analgesia for postoperative pain were included in the study; it seems to be the largest patient population from a single hospital. Data were collected as part of the hospital's quality improvement activities. By analyzing the questionnaires, we found that patients were satisfied with the pain therapy performed under the guidance of anesthesiologists, but predictors of satisfaction such as pain intensity and side effects (nausea, vomiting, constipation and difficulty in walking) decreased patient satisfaction considerably. Patients are aware of the fact that health care givers take postoperative care seriously and they do not want any untoward effects interrupting their postoperative care. They are trying to participate in the decision making and also to learn more about pain medicine.

Abstract
BACKGROUND There have been many studies using patient-controlled analgesia (PCA) and opioids for postoperative analgesia in children. In this study, we investigated the efficacy, usefulness and analgesic consumption of two different PCA programmes [bolus dose alone (BD) or bolus dose with background infusion (BD + BI)] to evaluate postoperative analgesia for children after emergency appendicectomy. METHODS Forty children, aged between 6 and 15 years and ASA class I or II, undergoing emergency appendicectomy were randomly allocated into two groups. The children were given a loading dose of pethidine 0.3 mg.kg-1 and 150 micro g.kg-1 bolus intravenously in group BD (n = 20) and pethidine 0.3 mg.kg-1 loading dose, 75 micro g.kg-1 bolus and 15 micro g.kg-1.h-1 background infusion in group BD + BI (n = 20). The lockout interval was 20 min in both groups. RESULTS There were no significant differences in pain, sedation and nausea scores during the 24-h postoperative period between the groups (P > 0.05). Pethidine consumption was significantly lower in group BD + BI than that in group BD for the first 24-h period (P < 0.05). CONCLUSIONS We demonstrated that both these PCA programmes were effective and reliable for postoperative pain relief in children. We believe that giving information about PCA to the children and their parents is useful during the preoperative period. However, the background infusion with lower bolus dose in PCA did not increase pethidine consumption.

Abstract
UNLABELLED In this systematic review, we compared the effectiveness of media-based patient education about anesthesia. Fifteen randomized controlled trials (n = 1506) were identified after a systematic search of electronic databases (MEDLINE, EMBASE, CINAHL, PSYCINFO, The Cochrane Controlled Trials Registry), published articles, and contact with authors. Outcomes assessed were anxiety, knowledge, and patient satisfaction. Anxiety levels before anesthesia were less intense in subjects receiving the video and printed information compared with those receiving no intervention (weighted mean difference of 3; 95% confidence interval [95%CI], 1-5 Spielberger's State and Trait Anxiety Inventory). Patients in the video group were more likely to answer all knowledge questions correctly compared with patients with no intervention (relative risk of 6.64; 95%CI, 2.05-21.52). The level of knowledge about pain management was higher in the video group compared with patients with no intervention (weighted mean difference of 17%; 95%CI, 9-25). However, the level of patient satisfaction with the intervention (expectation versus actual anesthetic experience) was similar between the groups (relative risk of 1.06; 95%CI, 0.93-1.22). This systematic review supports the use of video and printed information about general process and risks of anesthesia for patient education before surgery. IMPLICATIONS The effectiveness of media-based interventions for educating patients about general process and risks of anesthesia were compared in this systematic review. The use of video and/or printed information can decrease patient anxiety and increase patient knowledge. However, patient satisfaction was similar between media-based intervention and nonintervention groups.
