Postoperative pain following tonsillectomy remains a significant obstacle to speedy recovery and smooth convalescence. Inadequate analgesia causes poor oral intake and influences the length of hospital stay and ability to return to normal activity. Patient Controlled Analgesia (PCA) is a method of analgesia adminstration that consists of a computer driven pump with a button that the patient may press to adminster a small dose of analgesic drug. The aim of this study was to examine whether Intravenous Patient Controlled Analgesia (IV-PCA) can reduce postoperative pain after tonsillectomy. The 100 patients undergoing tonsillectomy with general anesthesia were divided into two groups. The PCA group patients (n=80) received a mixture of nalbuphine and ketorolac by Walkmed PCA infusor during first 48 postoperative hours. In control group (n=20), the patients received oral acetoaminophen (Tyrenol) regularly and tiaprofenic acid (Surgam) intramuscularly on a p.r.n basis. Analgesic efficacy was evaluated with visual linear analogue scale (VAS) and the adverse effects were evaluated with 4 point scale. The patients of PCA group had less pain than those of control group. The adverse effects in the PCA group were nausea and vomiting. This study suggests that IV-PCA may be safe and effective method of pain control after adult tonsillectomy and is better accepted than oral or intramuscular pain medications.

Objective : Retrospective analysis to compare the effect and complication of epidural patient-controlled analgesia (epidural PCA) with intravenous patient-controlled analgesia (IV PCA) for the treatment of the post-operative pain after posterior lumbar instrumented fusion. Methods : Sixty patients who underwent posterior lumbar instrumented fusion for degenerative lumbar disease at our institution from September 2007 to January 2008 were enrolled in this study. Out of sixty patients, thirty patients received IV PCA group and thirty patients received epidural PCA group. The pain scale was measured by the visual analogue scale (VAS) score. Results : There were no significant difference between IV PCA group and epidural PCA group on the PCA related complications (p=0.7168). Ten patients in IV PCA group and six patients in epidural PCA group showed PCA related complications. Also, there were no significant differences in reduction of VAS score between two groups on postoperative 2 hours (p=0.9618) and 6 hours (p=0.0744). However, postoperative 12 hours, 24 hours and 48 hours showed the significant differences as mean of reduction of VAS score (p=0.0069, 0.0165, 0.0058 respectively). Conclusion : The epidural PCA is more effective method to control the post-operative pain than IV PCA after 12 hours of spinal fusion operation. However, during the first twelve hours after operation, there were no differences between IV PCA and epidural PCA.

The concept of PCA(Patient Controlled Analgesia) was first described in 1968, by Sechzer. The earliest descriptions of actual self-administered PCA machines were by Forrest et al. In gastric bypass surgery, cesarian section, orthopedic surgery etc, PCA is widely used in the control of postoperative pain. Previous Studies have shown that PCA provides effective pain-control for the postoperative patient. The postoperative pain-control is a problem that should be solved in surgery. Especially in orthognathic surgery, it is not same as in the case of maxillofacial trauma surgery or of tumor surgery: most orthognathic surgery patients are under operation not accustomed to pains, and difficulties in pain-complaint due to IMF(Intermaxillary fixation), postoperative nausea, and vomiting are additional problem. In this study, we have compared PCA and IM analgesics with respect not only to time request but also to the quality of postoperative pain control.

Background: Postoperative delirium is relatively common. However, the relationship between intravenous patient-controlled analgesia (IV-PCA) and delirium has not been thoroughly investigated. The aim of this study was to evaluate the effects of IV-PCA on the prognosis of postoperative delirium in patients undergoing orthopedic surgery. Methods: Medical records of 129 patients with postoperative delirium were reviewed. Patients were divided into two groups according to whether they used IV-PCA with fentanyl and ketorolac. The IV-PCA group consisted of 73 patients who were managed with IV-PCA; the NO-PCA group consisted of 56 patients who were managed without PCA. Results: Incidences of multiple psychiatric consultations and prolonged delirium were significantly lower in patients using IV-PCA with fentanyl and ketorolac than in those without PCA. Conclusions: We recommend the use of IV-PCA for pain control and management of delirium in patients with postoperative delirium.

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.

Background : Patient-controlled analgesia(PCA) is a safe and effective technique for providing postoperative pain relief. Studies that compare epidural vs intravenous routes of opiate administration show conflicting results. We designed a prospective, randomized, controlled study to evaluate the safety and efficacy of epidural(EPI-PCA) morphine-bupivacaine versus intravenous (IV-PCA) nalbuphine when administered with a PCA system. Methods : Forty healthy women were randomly assigned to receive an epidural bolus of morphine 3 mg and 0.5% bupivacaine 10 ml, followed by a EPI-PCA with 0.01% morphine and 0.143% bupivacane (basal infusion 1 ml/hr, bolus 1 ml, lock-out interval 30 min) or intravenous bolus of nalbuphine 0.1 mg/kg followed by a IV-PCA with nalbuphine(basal infusion 1 mg/hr, bolus 1 ml, lock-out interval 20 min) for pain relief after cesarean delivery. This study was conducted for 2 days after cesarean section to compare the analgesic efficacy, side effects, patient satisfaction either as EPI-PCA or as IV-PCA. Results : EPI-PCA group had significant lower visual analog pain scale(VAS) at immediate postoperative period, whereas no significant difference was observed when pain was assessed at other time sequence. Urinary retention and pruritus were more frequent with EPI-PCA group, although the incidence of other side effects were the same. Conclusions : Although EPI-PCA with morphine-bupivacaine was of significantly lower VAS at immediate postoperative period, IV-PCA with nalbuphine is a safe and effective alternative to EPI-PCA with morphine-bupivacaine for providing pain relief after cesarean delivery. Further studies about IV-PCA with nalbuphine are needed to control the immediate postoperative pain and to further improve effective pain management.

Background: The postoperative pain in children and adolescents is most commonly managed by intramuscular injections of NSAIDs or opioids. This approach may result in fluctuating plasma drug levels and cycles of pain, comfort, and sedation. Patient-controlled analgesia(PCA) is a method of analgesia administration that consists of a computer-driven pump with a button that the patient may press to administer a small dose of analgesic drug. Materials & Methods: Forty ASA physical status 1 or 2 children and adolescents were divided into two groups. In the PRN group, patients received intramuscularly diclofenac(Valentac$^{(R)}$) on a p.r.n. basis. The PCA group patients received a mixture of nalbuphine and ketorolac by WalkMed$^{(R)}$PCA infusor. Analgesic efficacy was evaluated with NRS(numerical rating scale) and Faces Pain Rating Scale. The side effects were evaluated. Results: The patients of PCA group had less pain than those of PRN group. Complications were similar in both group. Conclusions: PCA with nalbuphine and ketorolac is a safe and effective methods of pain relief in children and adolescents after surgery, and is better accepted than intramuscular injections.

The purpose of this study was to investigate the effects of patient controlled analgesia(PCA) convergence education on postoperative pain management in spinal surgery patients. Sixty spinal surgery patients were included. For the experimental group(n=30), PCA education using video, booklet, and a PCA model practice was provided before surgery. The data were collected using questionnaire and were analyzed using descriptive statistics, ${\chi}^2-test$, Fisher's exact test, t-test and repeated measures ANOVA. PCA knowledge-attitude, PCA satisfaction and pain control satisfaction were higher in the experimental group than the control group(p<.001; p=.001; p<.001). Postoperative pain and frequency of additional analgesia use of the experimental group were significantly lower than those of the control group(p<.001; p=.001). This findings showed that the convergence PCA education of audiovisual aids with PCA practice training could be effective pain management intervention in patients undergoing spinal surgery. These apply to development of convergence nursing interventions in clinical practice.

Patient-controlled analgesia (PCA) has been widely used for postoperative pain control in medical surgery parts. Conventional intramuscular analgesia (IMA) is also effective in postoperative pain control, but it has some disadvantages that depend on patients' perception of pain and the anxiety that they endure caused by the delay of the injection time. This study was conducted to assess the efficacy and postoperative outcomes of intravenous PCA compared to IMA injections in 36 patients (BSSRO). Three factors were compared: amount of pain in PCA and IMA group ; amount of pain according to the sex in PCA and IMA group and the amount of pain according to the analgesia use. Results of this study did not demonstrate a statistically significant difference in any of these, using a p value of 0.05. The results of this study were as follows. : 1. There was no statistically significant difference in VAS pain score between IMA group and PCA group. 2. There was no statistically significant difference according to the sex. 3. There was no statistically significant difference according to the amount of PCA. The history of PCA is about 30 years and many literatures have reported about its effects, complications, methods, advantages and disadvantages. So, this study has some limitations of small sample size to conclude the effects of PCA. But when the decision about the method for postoperative pain control has to be made, it should be made based on patient or physician preference and cost factors rather than on the trend.

Purpose: The purpose of this study was to investigate the knowledge and practice of patient-controlled analgesia use and management (PCA-UM) among nurses. Methods: Data were collected from 182 nurses employed by four general hospitals having more than 300 beds in Daejeon. The data were collected using self-report questionnaires from November 4 to November 20, 2015. Collected data were analyzed using descriptive statistics, t-test, and ANOVA. Results: The average nurses' knowledge about PCA-UM was 14.8 points out of 20. PCA-UM knowledge was significantly higher for nurses with experience in PCA education (t=3.55, p<.001). Most participants (91.2%) wanted to get PCA training, 86.8% of them provided PCA education to patients after surgery. Approximately 62% of participants regularly evaluated the level of consciousness of patients with PCA. Conclusion: Findings indicate that the knowledge and practice of PCA-UM among nurses were insufficient to provide safe and effective pain management to postoperative patients with PCA. Therefore, it is concluded that it is necessary to develop standardized PCA education programs for nurses to provide safe and effective pain management to postoperative patients with PCA.
