1.Wake-up tests in scoliosis surgery using nalbuphine hydrochloride
Philippine Journal of Surgical Specialties 1985;7(1):35-40
Method: In this study, a modification of the Vauzelle method of wake up test was employed. A relatively new analgesic drug, nalbuphine Hydrochloride, was used in a balanced anesthetic technique, in searching for a better methid of anesthesia that will allow awakening and spinal cord monitoring during surgey.
Results: All patients were sucessfully awakened and were able to move their feet on command in 2 to 5 minutes (mean = 3.3 min. ) after the surgeon requested for the test. All patients were breathing spontaneously after the muscle relaxant was partially reversed. None required naloxone for the procedure. No complications related to the test were noted, such as self- extubation nor excessive struggling that may jeopardize the rod fixation. There were no neurological complications in this series.
Conclusion: The result of our study in 5 patients indicate that balanced anesthesia with nalbuphine hydrochloride can be recommended for intraoperative awakening to monitor spinal cord function during surgery. The rapid return of wakefulness effective analgesia, reduced blood loss, stable cardiovascular system and minimal respiratory depression, make it one of the anesthetics of choice for the special procedure.

BACKGROUND: The effectiveness of preemptive analgesia is still controversial. This study was designed to compare the effects of nalbuphine used in the pre-anesthesia period and after surgery for pain control when performing adenoidectomy or tonsillectomy in children. METHODS: Two hundreds four patients (aged 3 to 12 years) were randomly allocated into two groups: the preemptive group (group P, n = 98) and the intraoperative group (group I, n = 106). Nalbuphine 0.1 mg/kg was administered into the patients before induction of anesthesia in group P and it was injected at least 10 minutes after the beginning of surgery in group I. The anesthesia was performed in the conventional fashion. The pain score, the sedation score and the agitation score were checked and recorded in the postanesthetic room (PAR) at arrival (0), at 15 minutes and at 30 minutes. RESULTS: The pain scores for PAR 0, 15 and 30 minutes were significantly lower in group I than those in group P. The other sedation scores or agitation scores were similar in both groups. CONCLUSIONS: Nalbuphine used during the pre-anesthetic period was less effective than that used in the intraoperative period for pain control when performing adenoidectomy or tonsillectomy in children.

Nalbuphine, a mixed agonist-antagonist type opioid, can precipitate abstinence syndrome in opioid-dependent patients especially in large doses. We can prevent this syndrome by avoiding the injection of agonist-antagonist type opioid to the patient who already has used opioid for a long time, and the method of relatively small dose increments in its use. We experienced a case of opioid withdrawal symptom in chronically morphine-administered patient via epidural catheter after using intramuscular nalbuphine for analgesia. The symptom was promptly relieved by intravascular morphine injection without any problems.

This study was performed to compare the effects of epidural morphine and nalbuphine with general anesthesia for relief of pain after abdominal surgery. Patients were devided into three groups like Group I(General anesthesia), II(Epidural mor- phine) and III(Epidural nalbuphine). Pain score, gas passing and ambulation time were checked in all groups respectively. And side effects inclduing urinary retention and respiratory changes were evaluated too. The results were as follow. 1) The effects of epidural morphine and nalbuphine on pain relief were better than general anesthesia. And the effect of epidural morphine was superior to epidural nalbuphine too. 2) Ambulation time was the shortest in epidural morphine group. 3) Urinary retention, gas pasing time and respiratory changes were similar in a11 groups.

Nalbuphine, a recently introduced agonist-antagonist analgesic is considered to have analgesic potency similar to morphine in common clinical doses and has been reported to possess an ceiling effect on respiratory depression and to be effective in reversing respiratory depression induced by oxymorphone or hydromorphone. To evaluate the respiratory depression of nalbuphine hydrochloride, we use displacement of CO2 response by a rebreathing method as the index of respiratory depression. Eight healthy male subjects were given the nalbuphine at a dose of 0.1 mg/kg(nalbuphine group) or same volume of normal saline as a placebo(placebo group) intravenously, at interval of 2 weeks by a double blind test. We measured end-tidal PCO2(PETCO2), minute ventilation (VE), tidal volume(VT), and respiratyory frequency(f) at 10 min, 30 min, 60 min and 90 min after the injection. The linear regression equations of VE in response to PCO2 10 min, 30 min, 60 min and 90 min after injection are y=-11.3+0.34X(R=0.66), y=-11.5+0.3X(R=0.53), y=-9.85+0.33X(R =0.61) and y=-11.8+0.37X(R=0.67) in placebo group and y=-11.1+0.30X(R=0.54), y= 13.1+0.35X(R=0.64), y=-11.3+0.33X(R=0.66) and y=-13.4+0.37X(R=0.63) in nalbuphine group.There were no significant differences in the slope of the CO2 response curves between placebo group and nalbuphine group. But there were rightward displacements of the CO2 response curves, which were significant rightward displacements at 60 min and 90 min after the injection(P<0.05). These findings demonstrate that nalbuphine hydrochloride might be a respiratory depressant.

Cardiovascualar effects of a verapamil infusion were investigated in six dogs given nalbuphine-nitrous anesthesia. Verapamil 0.2 mg/kg was given followed by an infusion of 3 and 6 mcg/kg per minute. Verapamil significantly reduced the systemic vascular resistanee index and mean arterial pressure. The decrease in afterload led to an increase in cardiac index, since was little change in myocardial contractility(LV dp/dt). Administration of calcium chloride, 20 mg/kg, did not reverse tbe hemodynamic effects of verapamil. The data indicate that in dogs verapamil be even in high concentrations, during nalbuphine-nitrous oxide anesthesia without serious adverse hemodynamic sequences.

BACKGROUND: The effect of epidural analgesia for labor on obstetric outcome is controversial. The purpose of this study is evaluating the influence of epidural analgesia on cesarean section in nulliparous women. METHODS: We retrospectively investigated 979 nulliparous women ASA graded I - II. EPI (n = 230) was received epidural analgesia with 0.2% ropivacaine and 75microgram fentanyl. N-EPI (n = 749) was received no epidural analgesia but nalbuphine 10 mg intramuscularly. We compared the rate and causes of cesarean section, instrumental delivery rate and fetal outcomes between EPI and N-EPI. RESULTS: Cesarean section rate was not different between the EPI (18%) and N-EPI (23%). Causes of cesarean section were progress failure (83% in EPI and 80% in N-EPI) and fetal distress (17% in EPI and 20% in N-EPI) and there were no differences between two groups. Instrumental delivery rate was higher in EPI (8%) than N-EPI (5%). Fetal outcome was not different between two groups. CONCLUSIONS: Epidural analgesia did not increase cesarean section rate and did not influence on causes of cesarean section. But epidural analgesia increased the vacuum delivery rate.

BACKGROUND: The present study was performed to elicit what effect nalbuphine would have on isoflurane MAC (minimum alveolar concentration) in the patients undergoing lower abdominal surgery. METHODS: Sixty-two women were randomly allocated to one of five study groups to receive an intravenous injection of no nalbuphine (group I), 0.25 mg/kg (group II), 0.5 mg/kg (group III), 1.0 mg/kg (group IV), 1.5 mg/kg (group V). Anesthesia and tracheal intubation were induced with propofol 2 mg/kg, succinylcholine 1 mg/kg. Patients were inhaled at a preset end-tidal concentration of isoflurane, which was maintained for 20 min. Response to skin incision, movement or no movement, was determined 30 minutes after nalbuphine injection. The isoflurane concentration of the next patient in the same group moved up or down in steps of 0.1~0.3%, according to the previous patient's response. MAC was determined using the "up-down" method and logistic regression. RESULTS: The MAC's of isoflurane were 1.09 vol% end-tidal in the control group, 0.89 vol% in group II, 0.65 vol% in group III, 0.55 vol% in group IV, and 0.51 vol% in group V. CONCLUSIONS: It would be suggested that nalbuphine dose-dependently reduce the isoflurane MAC, and have ceiling effect on the reduction of isoflurane MAC.

BACKGROUND: This study was undertaken to reduce the side effects of epidural morphine through the addition of nalbuphine in 37 cesarean delivery. METHODS: Forty patients were divided into 2 groups; M(control) group: bolus administration of morphine 2 mg in 0.5% bupivacaine and continuous epidural 41 hour-infusion of morphine 7mg, N(experimental) group: bolus administration of morphine 2 mg in 0.5% bupivacaine combined with nalbuphine 10mg and continuous epidural 41 hour-infusion of morphine 7mg combined with nalbuphine 10mg via the Paragon infusor. RESULTS: During the postoperative 48 hours, their pain scores and side effects were recorded at 6, 12, 18, 24, 30, 36, 42 and 48 hours. The analgesic effects were good in two groups(mean VAS <3.0) and pain scores were statistically significant at 18 and 30 hour. The incidence of pruritus, nausea, vomiting and urinary retention was decreased in group N(p<0.05). CONCLUSIONS: We concluded that continuous epidural morphine combined with nalbuphine was one of recommendable methods to reduce side effects of morphine.

Journal of the Korean Surgical Society 2003;64(5):429-433
PURPOSE: The PerFix(R) plug is preformed as a Marlex mesh hernia plug, and consists of a fluted outer layer combined with an inner arrangement of eight mesh "petals." In contrast to hand-rolled hernia plugs, which can collapse on themselves, the PerFix(R) plug's petals maintain the device's open conelike shape. The fluted design allows the plug to more readily conform to the configuration of any indirect or direct defect. METHODS: Bewteen January 1996 and April 2000 126 conventional herniorrhaphies (C group: Bassini: 23, Shouldice: 15, McVay: 5, Lichtenstein: 83) were performed, and between May 2000 and April 2002, 124 PerFix(R) plug repairs (P group) were completed. The operation times, lengths of hospital stay, visual analogue pain scales, time of analgesics use, and complication and recurrence rates were compared between these two groups. RESULTS: The operation times and lengths of hospital stay for groups C and P were 56.4 vs. 31.1 minutes and 4.4 vs. 2.8 days, respectively, so where significantly shorter in the P group (P<0.01). The times of use for the analgesics, AAP and Nubaine, were 6.6 vs. 0.6 times and 1.7 vs. 0.9 times, in group C and P, respectively, so were significantly fewer in the P group (P<0.01). There were 5 recurrences (3.9%) in the C group during the follow up period (2~6 years), but there were none in the P group during the follow up period (5 months~2 years). The complications were similar in both groups. CONCLUSION: Compared with conventional surgical techniques, including the Lichtenstein tension free method, the PerFix(R) plug method is the most simple, and shows superiority in the following areas; the operation time, length of hospital stay, times of analgesics use and recurrence. However, with regard to the recurrence, longer follow up and observation periods are required.
