Evaluation of postoperative pain and toxicological aspects of the use of dipyrone and tramadol in cats

Objectives The aim of this study was to evaluate the effects of dipyrone and tramadol, used for 5 days, on postoperative pain, hematological and biochemical parameters, and oxidative markers on erythrocytes. Methods Twenty-eight healthy cats underwent ovariohysterectomy and were randomly allocated to four groups (each n = 7), according to the postoperative treatment administered intravenously: control (saline 1 ml q8h), DIP1 (dipyrone 25 mg/kg q24h), DIP2 (dipyrone 25 mg/kg q12h) and DIP3 (dipyrone 25 mg/kg q8h). All animals received tramadol (2 mg/kg q8h). Pain was assessed by visual analog (VAS), multidimensional UNESP and Glasgow pain scales for cats preoperatively and at 3, 6, 12, 24, 36 and 48 h after extubation. Venous blood was collected daily for 5 days, and on day 10, to perform a complete blood count (CBC) and determine the percentage of Heinz bodies (HBs). Serum biochemistry was evaluated preoperatively and on days 5 and 10; superoxide dismutase (SOD), catalase (CAT), myeloperoxidase (MPO) and lipoperoxidation were evaluated preoperatively and on days 3, 5 and 10. Results Control cats had higher pain scores than DIP3 cats by UNESP ( P = 0.0065), and DIP2 ( P = 0.0035) and DIP3 cats ( P = 0.0108) by VAS 3 h postoperatively. Rescue analgesia was required by two animals in the control group and one each in the DIP1 and DIP2 groups. There was no difference in SOD or CAT among groups. On day 5, MPO was more active in DIP2 than in DIP3 cats ( P = 0.0274). No difference in lipoperoxidation among treatment and control cats was found. CBC remained constant and without statistical difference among groups. Control, DIP2 and DIP3 cats presented a similar percentage of HBs on day 10. Biochemical variables were similar among groups and times. Conclusions and relevance The administration of dipyrone in cats, when used in combination with tramadol, did not ensure better analgesia than tramadol alone. Dipyrone did not significantly affect biochemical variables and oxidative markers, despite minimal, clinically irrelevant, hematological differences between groups.

ABSTRACTObjectives: There are conflicting reports in the past literature documenting the tendency of anemia in patients with periodontitis. Hence, this study was undertaken to assess whether periodontitis may cause an anemic state, by evaluating and comparing the red blood cell count, levels of hemoglobin, hematocrit, erythrocyte sedimentation rate (ESR), serum iron and serum ferritin between subjects with and without periodontitis.Methods: In this cross-sectional study, 140 systemically healthy subjects of both sexes (mean age 46 years) were recruited as control group (50 subjects without periodontitis) and study groups comprising 30 patients each with mild, moderate and severe chronic generalized periodontitis. Periodontal parameters and orthopantamographs were taken for all the groups and then 5 mL venous blood samples were sent for complete blood count and biochemical analysis. Inter-group and intra-group comparisons were performed for all the assessed parametersResults: The periodontal parameters were significantly higher (P≤.05) in periodontitis patients. Except for the ESR, which was significantly higher (P=.03) in the mild periodontitis group than the control group, hematological and biochemical parameters were not significantly different (P>.05) among the study groups or between the control and study groups. This difference was not evident even among the male and female subjects of both control and study groups (P>.05).Conclusions: Within the limits of this cross-sectional study, it can be concluded that the presence and severity of periodontitis may not affect the hematological and biochemical parameters of an individual. Further long term studies are however encouraged to validate these findings. (Eur J Dent 2012;6:287-294)softening of enamel (erosion).

Background Postoperative pain is one of the most complications in endoscopic sinus surgery. We aimed to evaluate the effect of the sphenopalatine ganglion block (SPGB) with bupivacaine on postoperative pain in patients undergoing endoscopic sinus surgery. Methods and Materials: In this clinical trial, 40 patients who indicated functional endoscopic sinus surgery were selected and then divided into 2 parallel groups as intervention and control. The intervention group was received 1.5 mL of bupivacaine 0.5% (injected to sphenopalatine ganglion) and while control was injected 1.5 mL of normal saline at the same injection site. Also, the visual analogue scale (VAS) was recorded immediately after anesthesia, along with 6, 12, 24, 48 h, 7 days, and 21 days after the operation for all patients. Results Immediately after anesthesia, as well as 6, 12, and 24 h after the operation, VAS in the intervention group was significantly lower than in the control group ( P < .05, for all). However, there were no significant differences between the 2 groups regarding VAS 48 h as well as 7 and 21 days after surgery ( P > .05, for both). Also, the rescue analgesia in the intervention group was significantly lower than in the control group ( P = .01). Conclusion SPGB with bupivacaine 0.5% (1.5 mL) was a simple, effective, safe, and noninvasive method for the management of postoperative pain in the patients undergoing endoscopic sinus surgery.

Abstract Background: preoperative oral pregabalin controls postoperative pain & decreases anesthetic requirements in total intravenous anaesthesia . In this study, we hypothesized that preoperative pregabalin reduces inhaled isoflurane requirements. Methods: Study was conducted in a university hospital, included 50 women (18-60 yrs.), ASA I or II, admitted to undergo elective abdominal hysterectomy under general anaesthesia. Time of study: June to September 2017. Exclusion criteria were allergy or hypersensitivity to pregabalin; patients on calcium channel blockers, antiepileptic drugs, antidepression drugs, any analgesics or sedatives, or oral hypoglycemic agents; and patients with severe cardiovascular, renal, hepatic or neurological dysfunction. Interventions: giving either oral pregabalin 150 mg or placebo to patients of both groups. Primary outcome measures: inhaled isoflurane requirements to maintain haemodynamics ± 20% of baseline& bispectral index (BIS) of 40 - 60, measured using MAQUET Flow-I anaesthetic machine. Secondary outcomes : attenuation of pressor response to intubation, postoperative pain, first time for rescue analgesia, total anaglesics and adverse effects. Results: Isoflurane consumption was significantly less in pregabalin group (7.80 ± 1.27ml h -1) versus (12.27 ± 2.49 ml h-1) in control group, (P= 0.00). Better haemodynamic stability was in pregabalin group after intubation. First postoperative hour :the mean VAS score was significantly higher in control group (7.10 ± 1.20) compared to pregabalin group (4.50 ± 1.70), P<0.001. All patients in control group received pethidine intramuscular. More patients in pregabalin group suffered dizziness. Conclusion: preoperative pregabalin 150 mg ,1 h before total abdominal hysterectomy has an inhaled anaesthetic-sparing effect, maintain haemodynamics and optimizes postoperative analgesia.

Rescue Analgesia

Background: The analgesic properties of ketamine are associated with its non-competitive antagonism of the N-methyl-D-aspartate receptor; these receptors exhibit an excitatory function on pain transmission and this binding seems to inhibit or reverse the central sensitization of pain. In the literature, the value of this anesthetic for preemptive analgesia in the control of postoperative pain is uncertain. The objective of this study was to ascertain whether preoperative low-dose ketamine reduces postoperative pain and morphine consumption in adults undergoing colon surgery.Methods: In a double-blind, randomized trial, 48 patients were studied. Patients in the ketamine group received 0.5 mg/kg intravenous ketamine before surgical incision, while the control group received normal saline. The postoperative analgesia was achieved with a continuous infusion of morphine at 0.015 mg∙kgˉ¹∙hˉ¹ with the possibility of 0.02 mg/kg bolus every 10 min. Pain was assessed using the Visual Analog Scale (VAS), morphine consumption, and hemodynamic parameters at 0, 1, 2, 4, 8, 12, 16, and 24 hours postoperatively. We quantified times to rescue analgesic (Paracetamol), adverse effects and patient satisfaction.Results: No significant differences were observed in VAS scores between groups (P>0.05), except at 4 hours postoperatively (P=0.040). There were no differences in cumulative consumption of morphine at any time point (P>0.05). We found no significant differences in incremental postoperative doses of morphine consumption in bolus, except at 12 h (P =0.013) and 24 h (P =0.002). The time to first required rescue analgesia was 70 ± 15.491 min in the ketamine group and 44 ± 19.494 min in the control (P>0.05). There were no differences in hemodynamic parameters or patient satisfaction (P>0.05).Conclusions: Preoperative low-dose-ketamine did not show a preemptive analgesic effect or efficacy as an adjuvant for decreasing opioid requirements for postoperative pain in patients receiving intravenous analgesia with morphine after colon surgery.

Background: There is currently no consensus regarding the appropriate treatment for postoperative pain after arthroscopic partial meniscectomy (APM). Prescribing a mild non–anti-inflammatory protocol of rescue analgesia may be sufficient to avoid the side effects of opioids or anti-inflammatories. Purpose/Hypothesis: The purpose was to compare the efficacy of pain reduction after APM in nonarthritic knees using betamethasone or celecoxib as anti-inflammatory analgesics versus acetaminophen or tramadol as rescue analgesics. The hypothesis was that there is no advantage for anti-inflammatories in achieving postoperative immediate pain relief after APM in nonarthritic knees compared with a simple nonopioid treatment. Study Design: Cohort study; Level of evidence, 2. Methods: This 3-arm controlled study evaluated postoperative pain levels and analgesic consumption in patients who underwent primary APM (under general anesthesia) at a single institution from December 2018 to December 2019. Patients were prospectively divided into 3 treatment groups: (1) betamethasone injection at the end of the procedure, (2) oral celecoxib prescription, or (3) neither treatment (control). All groups were instructed to take supplementary acetaminophen as needed. Patients were also allowed to take tramadol as needed to evaluate the need for opioids. At postoperative weeks 1, 2, and 3, patients completed the Knee injury and Osteoarthritis Outcome Score (KOOS) Pain subscale, and results were compared between time points and groups. Results: A total of 99 patients were included in the treatment groups: betamethasone group (32 patients), celecoxib group (30 patients), and control group (37 patients). At baseline, there were no statistically significant differences between the groups in age, sex, body mass index, level of activity, comorbidities, or surgical findings. KOOS Pain scores improved at every time point for all 3 groups ( P < .001), and no differences in scores were observed among groups. The consumption of acetaminophen or tramadol as rescue analgesia throughout the follow-up period was negligible among groups. Conclusion: During the first 3 postoperative weeks after APM in nonarthritic knees, pain was efficiently controlled by betamethasone or celecoxib; however, pain was also efficiently controlled by minimal consumption of acetaminophen with negligible use of tramadol. Therefore, acetaminophen could be prescribed as an effective first-line postoperative analgesic after APM.

Erector Spinae Plane Block

The Aim: This prospective, randomised controlled study aimed to investigate the efficacy and respiratory effects of postoperative pain management with erector spinae plane block (ESPB) in patients undergoing percutaneous nephrolithotomy surgery. Methods: A total of 60 ASA I-II patients aged 18–65 years, scheduled to undergo percutaneous nephrolithotomy (PCNL) were included. Patients were randomized either to the ESPB or control group. Ultrasound-guided ESPB with 15mL 0.5% bupivacaine at the T11 level was performed preoperatively using the in-plane technique in the ESP group. In both groups, 1gr of intravenous paracetamol was administered intraoperatively. Postoperative pain and agitation was evaluated using VAS, Dynamic VAS at 0, 6 and 24 hours and the Riker sedation-agitation scale at 0th Hours after surgery. Peak expiratory flow rate(PEFR) and SPO2 were measured in preoperative examination and at the 0th, 6th, 24th hours postoperatively. In the postoperative period, intravenous tramadol (100mg) was administered as a rescue analgesic when VAS ≥ 4. Time and number of the rescue analgesias, mobilization time and length of hospital stay were also recorded and analyzed. Results: A significantly lower VAS and DVAS were observed at 0th, 6th, 24th hours in the ESPB group (p < 0.05 for each timepoint). Also number of and time to rescue analgesia decreased in the ESPB group (p< 0.05 and 0.01 respectively). Postoperative/preoperative PEFR ratio was lower and there were more agitated patients in control group (p<0.05). Conclusion: ESPB may have additional clinical advantages while providing effective analgesia in patients who underwent PCNL comparing to intravenous analgesia.

Background: Laparoscopic cholecystectomy (LC) is now the gold standard technique for the treatment of gallstones disease. Although pain after LC is less intense than after open cholecystectomy, some patients still experience considerable discomfort during early postoperative hours. The aim of this study is to evaluate the effect of intraperitoneal and port site instillation of local anaesthetics on pain relief in early postoperative period following LC.Methods: This is a randomized, prospective analytical study among patients subjected to elective laparoscopic cholecystectomy. Patients were divided into 3 groups as; Group 1 was control, Group 2 was assigned to receive portside infiltration of bupivacaine, while group 3 received combined port site and intraperitoneal instillation of bupivacaine. The evaluation of postoperative pain was done according to the visual analog scale and the dosage of narcotic analgesics consumed and duration of hospital stay was also recorded.Results: At 1st post-operative hour, minimum VAS score was in group 3 (p=0.003). At 4th post-operative hour, Minimum VAS score was in group 3(p=0.015). At 8th post-operative hour, Minimum VAS score was in group 3, (p=0.044). Patients in group 3 received a lower total amount of rescue analgesia and they also had the shortest hospital stay after LC, compared to the patients in the other groups. As regarding the incidence of right shoulder pain, group 3 has minimal no of patients experienced rt shoulder tip pain.Conclusions: Infiltration of bupivacaine into port site and intraperitoneal space is simple, inexpensive and effective technique to minimize early postoperative pain and can be practiced for elective LC.

Objectives: To determine whether local anaesthetic infiltration of the long saphenous tunnel in patients undergoing unilateral, primary long saphenous stripping and multiple avulsions reduces early postoperative pain and requirement for opiate analgesia. Methods: Patients were randomized to receive either levobupivicaine or an equivalent volume of normal saline infiltrated around the groin incision and along the long saphenous tunnel. Analgesia and linear analogue pain scores at 1, 6 and 24 h postoperatively were recorded. Results: Fourteen patients received local anaesthetic and 13 patients received saline placebo. The anaesthetic group experienced a 22% reduction in pain scores 1 h postoperatively and a 48% reduction at 6 h although this failed to achieve statistical significance. However, the anaesthetic group were less likely to require morphine in recovery (2/14 [14%] versus 8/13 [62%]; P = 0.01). The high morphine requirements in the control group may have reduced the amount of pain those patients recorded on their pain scores and prevented statistical significance from being achieved. Conclusion: In varicose vein surgery, local anaesthetic infiltration to the groin wound and along the full length of the stripper track is associated with reduced postoperative pain and requirements for opiate analgesia.

Background. The aim of this retrospective study was to compare immediate postoperative pain scores and need for rescue analgesia in children who underwent pulpotomies and restorative treatment and those who underwent restorative treatment only, all under general anaesthesia.Methods. Ninety patients aged between 3 and 7 years who underwent full mouth dental rehabilitation under general anaesthesia were enrolled in the study and reviewed. The experimental group included patients who were treated with at least one pulpotomy, and the control group was treated with dental fillings only. The Wong-Baker FACES scale was used to evaluate self-reported pain and need for rescue analgesia. The data were analysed using the Kruskal-Wallis test, two samplet-tests, chi-square tests, and Pearson’s correlation analysis.Results. Ninety percent of the children experienced postoperative pain in varying degrees of severity. Immediate postoperative pain scores in experimental group were found to be significantly higher than in control group (x2=24.82,p<0.01). In the experimental group, 48% of the children needed rescue analgesia, compared with only 13% of the children in the control group (x2=13.27,p<0.05).Conclusion. Children who underwent pulpotomy treatment had higher postoperative pain scores and greater need for rescue analgesia than control group who underwent only dental fillings.

Background/Aim. Ropivacaine is a relatively new longacting local anesthetic. The aim of this study was to compare the postoperative analgesic effect of topical anesthetics ropivacaine 0.75% and lidocaine 2% with adrenaline in the postoperative treatment of periapical lesions in the maxilla. Methods. The study was conducted on 60 subjects, divided into two groups. The study-group received 0.75% ropivacaine without a vasoconstrictor, while the control group was treated with 2% lidocaine with adrenaline (1 : 80.000). Block anesthesia for n. infraorbitalis was used and local anesthetics were applied also on the palatine side for the end branches of n. nasopalatinus. The following parameters were observed: time elapsed from the application of an anesthetic until the first occurrence of pain after the surgery and first intake of an analgesic, the intensity of initial pain, pain intensity 6 h after the application of anesthetics and the total number of analgesics taken within 24 h after the completion of surgery. Results. The pain appeared statistically significantly earlier in the patients who had been given lidocaine with adrenaline (p < 0.001), while statistically significantly higher mean values of initial postoperative pain (p < 0.05) and pain intensity 6 h after the intervention (p < 0.01) were also registered in the same group of patients. In the period of 24 h upon the intervention, the study-group patients were taking less analgesics as compared to the control-group subjects (46.6% vs 73.3%), who were given analgesics earlier, although no statistically significant differences were observed related to the number of analgesic doses taken. Conclusion. The results of our study indicate a better postoperative analgesic effect of ropivacaine as compared to lidocaine with adrenaline.
