Comparison of postoperative analgesic efficacy of intraoperative single-dose intravenous administration of dexketoprofen trometamol and diclofenac sodium in laparoscopic cholecystectomy

STUDY OBJECTIVE The aim of this study is to compare the effects of intravenous single-dose dexketoprofen trometamol and diclofenac sodium 30 minutes before the end of the surgery on relief of postoperative pain in patients undergoing laparoscopic cholecystectomy. DESIGN A randomized fashion. SETTING AND PATIENTS Sixty (American Society of Anesthesiologist class I-II) patients undergoing laparoscopic cholecystectomy were divided into 2 groups INTERVENTION Patients in group DT received 50 mg dexketoprofen trometamol, whereas patients in group DS received 75 mg diclofenac sodium, intravenously 30 minutes before the end of surgery. MEASUREMENTS Postoperative pain intensity, morphine consumption with patient-controlled analgesia, time to first analgesic requirement, complications, rescue analgesic (intravenous tenoxicam 20 mg) requirement, and duration of hospital stay were recorded. MAIN RESULTS Postoperative pain visual analog scale scores were similar in the follow-up periods (P > .05). Patient-controlled analgesia morphine consumption was significantly less in group DT compared with group DS in all postoperative follow-up periods (2 and 4 hours: P < .01; 8, 12, 18, and 24 hours: P < .001). In the postoperative period, the first analgesic requirement time was significantly longer in group DT compared with group DS (P < .01). In addition, the number of patients requiring rescue analgesic was higher in group DS compared with group DT (P < .01). Other follow-up parameters were similar. CONCLUSION In our study, administration of intravenous single-dose dexketoprofen trometamol 30 minutes before the end of surgery provided effective analgesia with reduced consumption of opioids and requirement for rescue analgesic compared with diclofenac sodium in patients undergoing laparoscopic cholecystectomy. For this reason, we believe that, as a part of multimodal analgesia, dexketoprofen trometamol provides more effective analgesia than diclofenac sodium in patients undergoing laparoscopic cholecystectomy.

Conscious sedation for endoscopic retrograde cholangiopancreatography: dexmedetomidine versus midazolam.

OBJECTIVE Midazolam and dexmedetomidine, which are used for sedation during endoscopic retrograde cholangiopancreatography, were compared to evaluate the differences in efficacy, hemodynamics, and side effects. MATERIALS AND METHODS Fifty patients aged between 18 and 80 were randomly assigned to two groups according to American Society of Anesthesiologists (ASA) classification: Group M received midazolam with an initial bolus infusion of 0.04 mg/kg intravenously (i.v.), followed by additional doses of 0.5 mg i.v. midazolam, titrated to achieve a Ramsay sedation scale score of 3-4. Group D received dexmedetomidine with an initial bolus infusion of 1 mcg/kg/hr i.v. over 10 minutes, followed by a continuous infusion of 0.2-0.7 mcg/kg/hr, titrated to achieve an RSS of 3-4. A Mini Mental Status Examination (MMSE) was performed prior to sedation and in the recovery room once the Modified Aldrete Score (MAS) reached 9-10. Patient heart rates, arterial pressure and pain were evaluated. RESULTS Patients in Group D had lower heart rates at 20, 25, 30, 35 and 40 minutes following the initiation of sedation (p<0.05). There was no statistical difference in arterial pressure, RSS, MMSE or respiratory rate between the two groups. Coughing, nausea and vomiting occurred in 3 patients in Group M (12%), whereas no patient in Group D experienced these symptoms. The procedure elicited a gag response in 7 patients in Group M (28%) and in 4 patients in Group D (16%), with no significant difference between groups (p>0.05). When patient and surgeon satisfaction was compared between the two groups, Group D showed higher surgeon satisfaction scores (p<0.05). CONCLUSION The use of dexmedetomidine for conscious sedation during short, invasive procedures, such as endoscopic retrograde cholangiopancreatography, could be a superior alternative to the use of midazolam.

Comparison of Esmolol to Nitroglycerine in Controlling Hypotension During Nasal Surgery

OBJECTIVE The aim of this study was to compare esmolol to nitroglycerine in terms of effectiveness in controlling hypotension during nasal surgery. MATERIALS AND METHODS After approval by our institutional Ethics Committee, 40 patients were recruited and randomized into two drug groups: esmolol (Group E) and nitroglycerine (Group N). In group E, a bolus dose of 500 μg/kg esmolol was administered over 30 sec followed by continuous administration at a dose of 25-300 μg/ kg/min to maintain systolic arterial pressure at 80 mmHg. In group N, nitroglycerine was administered at a dose of 0.5-2 μg/kg/min. RESULTS During the hypotensive period, systolic arterial pressure, diastolic arterial pressure, mean arterial pressure, and heart rate were decreased 24%, 33%, 27% and 35%, respectively, in group E (p<0.001, p<0.001, p<0.001, p<0.001) and were decreased 30%, 33%, 34% and 23%, respectively, in group N (p<0.001, p<0.001, p<0.001, p<0.001). The decrease in heart rate was higher in group E during the hypotensive period (p=0.048). During the recovery period, diastolic arterial pressure and heart rate were decreased 9% and 18%, respectively, in group E (p=0.044, p<0.001). Systolic arterial pressure, diastolic arterial pressure, and mean arterial pressure were decreased 7%, 3% and 7%, respectively, in group N (p=0.049, p=0.451, p=0.045). CONCLUSION Esmolol provides hemodynamic stability and good surgical field visibility and should be considered as an alternative to nitroglycerine.

Deksmedetomidin ve esmololün derlenme döneminde oluşan artmış hemodinamik yanıt tedavisindeki etkinliklerinin karşılaştırılması

Objectives: Our aim was to compare effectiveness of esmolol and dexmedetomidine in the treatment of increased hemodynamic response during anesthesia recovery period. Materials and methods: 60 ASA I-II patients whom scheduled for elective surgery with endotracheal intubation were randomized before extubation according to their hemodynamic parameters that were increased 20% of their baseline values in order to receive 1mg/kg esmolol (Group Esmolol, n= 30) or 0.5 µg/kg dexmedetomidine (Group Dexmedetomidine, n= 30). Heart rate (HR), systolic and diastolic blood pressures (SBP,DBP), peripheral oxygen saturation (SpO 2 ), end tidal carbon dioxide (ETCO 2 ) values, extubation time, recovery time were recorded. The duration till having pain requiring analgesic was recorded and cognitive functions were evaluated with short memory orientation concentration test at 20th and 50th minutes. Results: After drug, HR reductions were significant at all periods in group Dexmedetomidine (Z2-Z10: p<0.001, Z11:p=0.001, Z12, p=0.006). In group Dexmedetomidine SBP value was high at 3rd min after drug (p<0.001), and SBP values were lower in all periods before and after extubation (Z6- Z10: p<0.001, Z11: p=0.02, Z12: p=0.04). In group Dexmedetomidine DBP value was higher at 1st min after drug (p=0.001), DBP values were lower at 10th min after drug and before extubation (p= 0.045, p=0.001). The duration of pain requiring analgesic and recovery period were longer in dexmedetomidine group (p<0.001, p<0.001). Conclusions: Although esmolol and dexmedetotimidine attenuated hemodynamic response during recovery period, dexmedetotimidine was more effective in hemodynamic stabilization and the duration of pain requiring analgesic was longer. Esmolol provided faster recovery time. J Clin Exp Invest 2012; 3(1): 53-60

Fatal Hydrothorax Due to Misplacement of a Nasoenteric Feeding Tube

Blind nasoenteric intubation was attempted in a patient with chronic parkinsonism. The tube was inadvertently misplaced and penetrated the left pleural cavity. The next day, the patient developed cardiopulmonary arrest during dietary supplement infusion. This complication ultimately led to the patients death. We have reviewed the known complications of nasoenteric tube placement and conclude that difficult insertion in patients at risk from tube misplacement should be followed by chest radiography to confirm the correct placement of the tube before nutritional support is started.

Mobbing Exposure of Anaesthesiology Residents in Turkey

OBJECTIVE In recent years, psychological problems that are caused by working conditions, like burn out syndrome, are more commonly observed. In our study, we aimed to evaluate mobbing exposure, factors causing mobbing and precautions for mobbing in residency students who are educated in anaesthesiology and reanimation clinics in Turkey. METHODS After obtaining consent from the ethics committee, we sent our questionnaires to the secretariats of the departments by postal mail. Completed questionnaires were collected in our departments secretariat blindly and randomly mixed. One hundred and one participants were returned the questionnaires. Data was statistically analysed in SPSS 21.0 software programme. RESULTS During residency programme, sated to have experienced mobbing one or more time. Interestingly, 5.9% participants complained of physical mobbing. Mobbing exposure was more common in females. The most serious new onset psychosomatic symptoms stated during residency were committing suicide (2%), addiction (16%), severe depression (18%), panic attack (8%), more accidents (7%) and tendency of violence (15%). In mobbing group there was statistically significant dissatisfaction rate. CONCLUSION In professions where mobbing is common, incidences of psychiatric diseases and suicide attempts are high are increased. Who are under risk for experiencing mobbing should be noticed carefully to ensure good judgement and problems should be inspected objectively in a detailed manner. Anesthesiology societies and other medical professional societies should establish mobbing committees. Thus, mobbing problems can be resolved and healthy career oppurtunities can be presented to residents.

Do metoclopramide and ondansetrone alter mivacurium-induced neuromuscular blockade? - a randomised trial

BACKGROUND We aimed to investigate the effects of metoclopramide and ondansetrone on mivacurium neuromuscular blockade. METHODS Seventy five, ASA I-II patients, aged 18-65 and scheduled for elective surgery requiring tracheal intubation were included in the study. The patients received metoclopramide 10 mg, ondansetrone 4 mg or normal saline 5 mL; group M, group O, group NS (n=25), respectively. Before anesthesia study drugs were administered in a volume of 5 mL. The level of plasma cholinesterase were obtained before and 5 minutes after the administration of study drugs and 5 minutes after the administration of mivacurium. Onset time, T25, T75, T25-75, T90 levels were compared with each other and differences between each patients were investigated. After recording T90, the study was terminated and surgery was started. RESULTS Onset time was significantly shorter in group M, than the other two groups. Onset time in group O was significantly shorter than in group NS. In Group M T25, T75, T90 and recovery indices were significantly greater than in Group NS (p<0.001). In Group O T25, T75 were greater than Group NS (p<0.01 and p<0.05, respectively). In Group M T75, T90 and emergence indices were significantly higher than Group O (p<0.001, p<0.01, p<0.001, respectively). In Groups M and O, plasma cholinesterase levels decreased significantly (p<0.001) after administration of study drugs and mivacurium. Plasma cholinesterase also was reduced in Group NS 5 minutes after the administration of mivacurium (p<0.001). CONCLUSION Ondansetrone is believed to be more reliable agent than metoclopramide when used with mivacurium.

Esmolol reduces pain on injection of propofol

Abstract Background and objective: This randomized, double-blind, placebo-controlled study was carried out to determine the effect of esmolol on the incidence and severity of pain during propofol injection using a venous retention technique, and to compare it with lidocaine and placebo. Methods: After institutional ethical approval, 150 ASA I-II patients (ages 21–70) undergoing general anaesthesia for elective surgery were randomized to receive esmolol (0.5 mg/kg) (n = 50), lidocaine (0.5 mg/kg) (n = 50) or saline (placebo group, n = 50) diluted into a 5 ml solution after tourniquet application (70 mmHg) on the forearm. The occlusion was released after 30 seconds and 25% of the calculated induction dose of propofol was administrated at the rate of 0.5 ml/s. The patients were observed and asked immediately if they had pain in the arm, and the response was recorded. Results: Twenty-seven patients in the esmolol group, 28 in the lidocaine group, and 8 in the placebo group reported no pain (both groups vs. pl...
