Morfina nasal: Avaliacao da analgesia e dos efeitos colaterais no tratamento da dor pos-operatoria em criancas

Background and Objectives - Postoperative pain is one of the major discomforts but often under treated, especially in the pediatric patient. The aim of this study was to evaluate nasal morphine postoperative analgesia as an alternative drug administration route and show its applicability, effectiveness, tolerability and side effects. Methods - Participated in this study 20 patients aged 3 to 13 years, physical status ASA I and II sequentially submitted the different small and medium-size surgeries. Analgesia was obtained with nasal morphine hydrochloride in aqueous solution in variable concentrations of 2%, 1%, 0.5%, 0.25% and 0.125%. The dose for each instillation has been 0.1 mg.kg -1 at three-hour intervals for 36 postoperative hours. Quality of analgesia in pre-verbal age patients was evaluated by a pain intensity scale based on facial expression and crying, sleep, motor activity, sociability and food ingestion was used. Standardized evaluations were performed at 3-hour intervals. A four-grade scale was used to evaluate tolerability, where: 1) Good; 2) Regular; 3) Bad; 4) Very bad. Result - Postoperative analgesia results have proven to be good and safe, especially from the third evaluation on (6 hours). Drug tolerability has been good, although side effects were observed, especially nausea and vomiting. Conclusions - Patients and relatives accepted the method very well. The nasal route was considered an adequate way for opioid administration although more studies are needed to accept it as a routine for postoperative morphine analgesia.

Articaine and mepivacaine efficacy in postoperative analgesia for lower third molar removal: a double-blind, randomized, crossover study

Objective: Comparison of the clinical efficacy of 4% articaine in relation to 2% mepivacaine, both with 1:100,000 epinephrine, in the prevention of postoperative pain after lower third molar removal. Study design: Twenty patients underwent removal of bilateral lower third molars under local anesthesia (articaine or mepivacaine) in 2 separate appointments, in a double-blind, randomized, and crossed manner. Objective and subjective parameters were recorded for paired comparison of postoperative courses. Results: Duration of analgesia provided by articaine and mepivacaine was 198.00 ± 25.86, and 125.40 ± 13.96 min, respectively (P = .02), whereas the duration of anesthesia was 273.80 ± 15.94 and 216.85 ± 20.15 min, respectively (P = .06). Both solutions exerted no important effects upon arterial pressure, heart rate, or oxygen saturation (P > .05). Conclusions: Articaine provides a longer period of analgesic effect and a tendency for a longer period of anesthesia as compared to mepivacaine. The presence of a vasoconstrictor agent in local anesthetic solutions does not seem to influence hemodynamic parameters during lower third molar removal in healthy subjects. © 2006 Mosby, Inc.

Abscesso do músculo psoas em paciente submetida à analgesia por via peridural. Relato de caso

BACKGROUND AND OBJECTIVES: Psoas muscle abscess is a rare complication of epidural analgesia. The adequate approach to this complication is fundamental for a good resolution. The objective of this report was to discuss the diagnosis and treatment of psoas muscle abscess. CASE REPORT: A female patient, 65 years old, with neuropathic pain in the lower limbs, difficult to control with systemic drugs. The patient was treated with epidural opioid and local anesthetic as an alternate treatment. Twenty days after the continuous epidural administration, the patient complained of lumbar pain, headache, and fever. A CT scan of the pelvis showed an abscess of the psoas muscle, thus, closed drainage and antibiotics were indicated. CONCLUSIONS: An adequate, continuous supervision of the patient is necessary when an epidural catheter is placed, and it should continue after its removal. © Sociedade Brasileira de Anestesiologia, 2007.

Sobre a analgesia pós-operatória da morfina, cetamina ou da associação em cadelas submetidas à ovariossalpingohisterectomia eletiva

This study aimed to evaluate the post operative analgesic effects of morphine or ketamine alone or their combination in 24 healthy bitches, weighing 11.01±8.69kg and aging 27±17 months, submitted to elective ovariohysterectomy. The animals were distributed to one of the three treatments after the anaesthetic induction: morphine (GM, n=8, 0.5mg kg-1 IM), ketamine (GK, n=8, 2.5mg kg-1 IM) or ketamine combined to morphine (GKM) using the same doses previously described. Sedation score and pain assessment were performed blindly two hours before surgery and at 1, 2, 4, 8, 12, and 24 hours after extubation, using the Dobbins scale (sedation) and visual analogue scale (pain) and Glasgow modified pain scale (GMPS). Rescue analgesia was performed with 1.0mg kg-1 of morphine and if not sufficient, followed by 0.2mg kg-1 of meloxicam, both IM, when the GMPS reached above 33% of the total score. Non parametric data were analyzed using Friedmańs test followed by Dunńs test for differences in time. Kruskal-Walliś test followed by Dunńs test were used to investigate differences in the number of analgesic rescues and among groups at each time. Parametric data were evaluated by ANOVA followed by Tukey's test (P<0.05). Except for GMPS, where the values of GM were greater than for GKM at 1h post-extubation, there were no other differences among groups. The number of rescue analgesia was greater in GM (11 in total; twice in 3 animals,) when compared to GKM (3; twice in 1 animal) and GK (2; twice in 1 animal). Analgesia provided by pre-incisional ketamine was more effective when compared to morphine. According to that, ketamine alone may be used as a preemptive analgesic in bitches undergoing ovariohysterectomy; however, rescue analgesia may be necessary.

Comparison of intrarectal ozone, ozone administered in acupoints and meloxicam for postoperative analgesia in bitches undergoing ovariohysterectomy

Since all analgesics currently available for use in dogs have been associated with some adverse effects, the search for an effective analgesic that does not cause harm is important. This study investigated the postoperative analgesic effects of ozone administered either intrarectally or into acupoints in bitches undergoing ovariohysterectomy (OH). Twenty-four healthy adult bitches were randomly assigned to one of the three treatments 10min after sedation, as follows: 0.2mg/kg of intramuscular (IM) meloxicam (M); rectal insufflation of 10mL of 30μg/mL ozone (OI), or acupoint injection of 0.5mL ozone (30μg/mL; OA). Following sedation with acetylpromazine, anaesthesia was induced with propofol and fentanyl and maintained with isoflurane/O2. Pain was assessed using the modified Glasgow pain scale (MGPS) and the visual analogue scale (VAS) on the day before surgery, before anaesthesia, and at 1, 2, 4, 6, 8, 12 and 24h after surgery. Rescue analgesia was performed using 0.5mg/kg of morphine IM if MGPS was >3.33 points.No statistically significant differences in pain scales were found among the three analgesic protocols or the time points in each group ( P>. 0.05). Two dogs treated with OA required rescue analgesia. Meloxicam, rectal insufflation of ozone and ozone injected into acupoints provided satisfactory analgesia for 24. h in bitches undergoing elective OH. Ozone had no measurable adverse effects and is an alternative option to promote pain relief. © 2013 Elsevier Ltd.
