  • Background: The adductor canal block (ACB) is an effective intervention for postoperative analgesia following total knee arthroplasty (TKA). However, the ideal ACB regimen has not yet been established. We compared the analgesic effects between a continuous ACB group and fentanyl-based intravenous patient-controlled analgesia (IV-PCA) with a single-shot ACB group. Methods: Patients who underwent TKA were randomly allocated to either a continuous ACB group (Group CACB) or IV-PCA with a single-shot ACB group (Group IVACB). Before the surgery, ultrasound guided ACB with 0.5% ropivacaine 20 cc was provided to all patients. Before skin incision, the infusion system (0.2% ropivacaine through an adductor canal catheter in group CACB vs. intravenous fentanyl in group IVACB) was connected. The postoperative pain severity; the side effects of local anesthetics and opioids; administration of rescue analgesics and anti-emetics; and sensorimotor deficits were measured. Results: Postoperative pain severity was significantly higher in the IVACB group at 30 min, 4 h, 24 h, and 48 h after surgery. The averages and standard deviations (SD) of the NRS score of postoperative pain were $0.14{\pm}0.37$, $4.57{\pm}2.37$, $6.00{\pm}1.63$, and $4.28{\pm}1.49$, respectively in the IVACB group. Rescue analgesic requirements and quadriceps muscle strength were not statistically different between the groups throughout the postoperative period. Moreover, rescue antiemetic requirements were higher in group IVACB than group CACB. Conclusions: In this study, the continuous ACB provided superior analgesia and fewer side effects without any significant motor deficit than the IV-PCA with a single-shot ACB.

  • Background: An understanding of the features of postoperative pain is essential for optimal analgesic dosing strategies. Using a visual analogue scale (VAS) score and patient controlled analgesia (PCA) infusion pattern analysis, an anesthesiologist can estimate when and how severely patients suffer from pain. Several reports have been published about circadian changes in the pain threshold. Postoperative pain was analyzed retrospectively in 250 patients who underwent orthognathic surgery. Methods: A total of 250 patients were allocated into two groups according to the time of recovery from anesthesia. Patients in the early group (group E) recovered from anesthesia before 06:00 p.m. Patients in the late group (group L) recovered from anesthesia after 06:00 p.m. All patients received intravenous patient controlled analgesia (IV PCA) at the end of the operation. The VAS score of pain intensity was measured. Self-administration of bolus analgesic from the IV PCA device was also analyzed according to actual time and elapsed time. Results: VAS scores showed no difference between the two groups except 36 hours after recovery from anesthesia. On POD1, there were two peaks for self-administration of bolus analgesics in group L and one peak in the morning for group E. Two peaks each in the morning and in the afternoon were shown in both groups on POD2. Conclusions: Diurnal variance in pain should be considered for effective dosing strategies.

  • Background: Preoperative analgesia may prevent nociceptive inputs generated during surgery from sensitizing central neurons and therefore may preempt postoperative pain. Although preemptive analgesia has shown to decrease postinjury pain in animals, studies in human are not consistent. We studied whether epidural morphine injection before surgical incision could affect postoperative pain and analgesic demands, compared with injection after removal of specimen. Methods: Forty patients scheduled for radical subtotal gastrectomy were randomly assigned to one of two groups for prospective study in a double-blind manner. Group 1 received an epidural injection of 3 mg of morphine in 8 ml of 0.9% saline before surgical incision, and Group 2 after removal of specimen. Postoperative pain relief was provided with I.V. patient controlled analgesia (PCA) system. Numerical rating scales for pain and mood, Prince Henry Hospital scores for pain, cumulative PCA analgesic consumptions, and incidence of side effects were assessed at 2, 6, 12, 24, 48 hours after operation. Results: Cumulative PCA analgesic consumption in group 1 was significantly less than in group 2 at 2, 6 hours after surgery. Pain scores and the incidence of side effects were similar in both groups. Conclusions: Preoperative analgesia with epidural morphine showed little difference in patient controlled analgesic consumption after upper abdominal surgery compaired to intraoperative morphine.

  • Background: Ketorolac($Tarasyn^{(R)}$) is a non-steroidal anti-inflammatory drug(NSAID) which has shown to be an effective postoperative analgesic available parenterally, and when combined with morphine can reduce its requirement. The analgesic efficacy and adverse effects of continuous infusion of ketorolac added to morphine IV PCA was evaluated in 60 women after abdominal hysterectomy. Methods: Patients were assigned to receive either morphine intravenous(IV) bolus followed by morphine IV patient controlled analgesia(PCA), or ketorolac 30mg IV and continuous IV infusion at 4.0mg/hr in combination with the above regimen. The authors evaluated PCA morphine used, pain assessment(verbal pain intensity score and visual analogue scale) and side effects at 2, 4, 6 and 24hrs during pain control. Results: Continuous infusion of ketorolac decreased the PCA morphine usage significantly(30.4 ---> 19.6 mg : p=0.007) at 24hrs postoperatively. Significant differences were seen favoring ketorolac infusion in pain intensity and visual analogue scale both at rest and during movement. There were no differences in incidences of deep sedation, nausea & vomiting. But the ketorolac group they complained of dizziness more than morphine only group. Little pruritus was recorded in either groups. Conclusions: The authors conclude continuous IV infusion of ketorolac in conjunction with morphine PCA provide effective analgesia after low abdominal surgery.

  • Purpose: The purpose of this study was to identify the effects of the patient controlled analgesics (PCA) education program (including practicum) on post-op pain suffered by patients who have undergone gynecologic laparoscopic surgery. Methods: The research was designed for a nonequivalent control group before and after the test design. The subjects of this study were 54 in all and were divided into an experimental group and a control group. The program consisted of a brochure for PCA use and a practicum with an actual PCA instrument. Data were collected with questionnaires and observations and were analyzed on the basis of frequency, percentage, mean, standard deviation, ${\chi}^2$ and t-test. Results: Complaints regarding pain by the experimental group were significantly less than those of the control group in both post-op 24-hour and post-op 48-hour reporting. The experimental group pressed the PCA button much less frequently than the control group in post-op 24 hours. However, there were no significant differences in side effects between the two groups. Conclusion: Based on the results of this study, this PCA education program can be useful in the clinical nursing field and helpful for patients who use PCA.

  • Background: Ketamine, an N-methyl-D-aspartate receptor antagonist, might play a role in postoperative analgesia, but its effect on postoperative pain after caesarean section varies with study design. We investigated whether the preemptive administration of low-dose intravenous ketamine decreases postoperative opioid requirement and postoperative pain in parturients receiving intravenous fentanyl with patient-controlled analgesia (PCA) following caesarean section. Methods: Spinal anesthesia was performed in 40 parturients scheduled for elective caesarean section. Patients in the ketamine group received a 0.5 mg/kg ketamine bolus intravenously followed by 0.25 mg/kg/h continuous infusion during the operation. The control group received the same volume of normal saline. Immediately after surgery, the patients were connected to a PCA device set to deliver 25-${\mu}g$ fentanyl as an intravenous bolus with a 15-min lockout interval and no continuous dose. Postoperative pain was assessed using the cumulative dose of fentanyl and visual analog scale (VAS) scores at 2, 6, 24, and 48 h postoperatively. Results: Significantly less fentanyl was used in the ketamine group 2 h after surgery (P = 0.033), but the difference was not significant at 6, 12, and 24 h postoperatively. No significant differences were observed between the VAS scores of the two groups at 2, 6, 12, and 24 h postoperatively. Conclusions: Intraoperative low-dose ketamine did not have a preemptive analgesic effect and was not effective as an adjuvant to decrease opioid requirement or postoperative pain score in parturients receiving intravenous PCA with fentanyl after caesarean section.

  • Background: This study was conducted to evaluate the efficacy of a parenteral nonsteroidal anti-inflammatory agent for management of post-surgical pain and its effect on hospital stay and long-term surgical outcome. Methods: Total of 40 patients undergoing lumbar discectomy were randomly assigned to two groups, receiving either 1) 30 mg intravenous ketorolac upon surgical closure, every 6 hours for 36 hours, and morphine IV PCA (intravenous patient controlled analgesia), or 2) only morphine PCA. A blinded investigator recorded; the visual analog pain scores, total postoperative narcotic consumption, complications by morphine PCA, length of hospitalization (from surgery to discharge), and long-term outcome at 6 weeks. Results: The patients who received IV ketorolac and morphine PCA reported significantly lower visual analog pain scores than patients receiving only morphine PCA. Cumulative morphine doses were significantly lower in the ketorolac group (P<0.001). There was no significant difference between groups in the frequency of side effects related to morphine PCA. Mean length of hospitalization was longer for patients receiving only morphine PCA, but there was no statistical significance. Six weeks after surgery, four (20.0%) patients who received only morphine PCA suffered persistent back pain. In contrary, all those patients who received ketorolac were free of back pain at follow-up (P<0.05). Conclusions: These results suggest that intermittent IV bolus ketorolac, when used with opioid IV PCA is more effective than opioid IV PCA alone for postoperative pain following lumbar disc surgery. However, this strategy did not contribute to early discharge from hospital after lumbar disc surgery. The effect to long-term surgical outcome was not conclusive.

  • Objective: Opioid analgesics, for postoperative pain management, are an indispensable group of medication; however, they also have a variety of adverse drug reactions (ADR). Multimodal methods, combining non-opioid analgesics with opioid analgesics, have been investigated to increase the effects of analgesics and reduce ADR with opioid-sparing effects. The purpose of this study was to compare the effects of patient-controlled analgesia (PCA) with fentanyl alone, and PCA with fentanyl and intravenous (i.v.) propacetamol to determine the effects of pain control, cumulative opioid usage, and opioid ADR. Methods: The subjects were patients who underwent total knee arthroplasty at the Seoul Veterans hospital from January 1, 2015 to December 31, 2016. The study period was from postoperative day 0 (POD0) to day 3 (POD3), and the retrospective study was conducted using electronic medical records. Results: Pain severity was significantly low at POD1 (p = 0.017), POD2 (p = 0.003), and POD3 (p = 0.002) in the multimodal group. The fentanyl only group frequently reported both moderate and severe pain at a statistically significant level. This was consistent with the analysis of the pro re nata (PRN) intramuscular analgesia usage at the time of numerical rating scale (NRS) 4 and above. The opioid-sparing effect confirmed that the average opioid dose equivalent to i.v. morphine dose was 9.4 mg more than that used for the multimodal group in the fentanyl only group. The ADRs and length of stay between the two groups were not statistically different. Conclusion: The results of this study suggest that the combination therapy of fentanyl and i.v. propacetamol is superior to fentanyl monotherapy.

  • Background: Preemptive analgesia may decrease postoperative pain by preventing nociceptive inputs generated during surgery. The preemptive effect of intravenous nalbuphine was examined in gynecological surgery. Methods: Forty female patients scheduled for gynecological surgery were randomly allocated into two groups. Each patient received 10 mg of intravenous nalbuphine as a bolus dose at the closure of peritoneum in group I (n=20) and before the skin incision in group II (n=20). After the bolus dose, the intravenous patient controlled analgesia (IV-PCA) which contained 50 mg of nalbuphine, 120 mg of ketorolac, 0.25 mg of droperidol and 90 ml of 5% dextrose water was given continuously at the rate of 2 ml/min. The postoperative visual analogue scale pain score (VAS), the total amount of the analgesics used, the degree of satisfaction of the patients and the developement of side effects were examined for 2 days. Results: VAS were significantly lower in group II than in group I after 9 and 12 hours. The cumulative consumption of analgesics in group II was significantly less than in group I. Most patients were satisfied with this regimen. There were no remarkable side effects. Conclusions: Preemptive analgesia with intravenous nalbuphine decreased postoperative pain and analgesic requirement. The analgesic effect of IV-PCA with nalbuphine-ketorolac was effective in control of postoperative pain in gynecologic surgery.
