A Rare Cause of Epistaxis: Nasopharyngeal Leech Infestation.

Leeches are rare cause of foreign body in airways. A 23-year-old male, experiencing epistaxis and difficulty in swallowing is presented. During nasopharyngoscopy, a moving leech was observed on the nasopharynx posterior wall in midline location, and removal of the leech was decided under general anaesthesia. The flexible nasopharyngoscopy was inserted, but removal was unsuccessful due to the leech's movements. Leeches are blood-sucking parasites, so neuromuscular blocking agent was given to prevent the movement. After administration, motion of the leech was lost and easily removed undamaged. In patients presenting with unexplained epistaxis, hemoptysis, dyspnea, and foreign body sensation in the airway, leech infestation should be included as the differential diagnosis and history of contact with stream water should be questioned. We concluded that use of low dose neuromuscular blocking agents facilitates the gentle removal, and could be necessary for successful management of removal of leech under general anaesthesia.

Transnasal Sphenopalatine Ganglion Block for Management of Postdural Puncture Headache in Non-Obstetric Patients.

BACKGROUND: This study investigated the efficacy and safety of transnasal sphenopalatine ganglion block (SPGB) for treatment of postural puncture headache (PDPH) in non-obstetric patients. METHODS: This retrospective study was conducted at the Ankara Research and Educational Hospital, in Turkey, and included 26 non-obstetric patients (age, ≥18 years) who were diagnosed with PDPH and unresponsive to conservative therapy or unable to continue it because of side effects. Transnasal SPGB was performed in each nostril. Pain severity was assessed with the Visual Analogue Scale (VAS) at 15 min, 30 min, 24 h, and 48 h after the procedure, while patients were seated. The patients were monitored for 48 h for adverse effects (AEs). Patient treatment satisfaction was assessed at 48 h after the procedure by using the Patient Global Impression of Change (PGIC) scale. RESULTS: Headache at 15 min post-procedure was relieved rapidly. At 24 h post-procedure, nearly half of patients (42.3%) had no pain, and all patients (100%) had a VAS score of <3. Nasal discomfort, throat numbness, and nausea were AEs reported after SPGB; however, these AEs were completely relieved at 24 h after the procedure. According to the PGIC scale scores at 48 h post-procedure, 73.1% of patients evaluated themselves as "much improved" and 26.9% evaluated themselves as "very much improved". CONCLUSION: When PDPH does not respond to conservative treatment, it may be treated effectively with transnasal SPGB, which is a noninvasive, safe, well-tolerated, and straightforward method with a low complication rate.

Effect of sevoflurane anaesthesia on nasal mask in endoscopic retrograde cholangiopancreatography: is it a preferred alternative?

Background/aim: Endoscopic retrograde cholangiopancreatography (ERCP) often requires deep sedation. Propofol provides adequate sedation and amnesia at subhypnotic doses, but safe guarding the patient's airway is important for preventing respiratory depression or hypoxic events. This study compared sedation levels, operator satisfaction, intraoperative and recovery characteristics using sevoflurane with nasal mask and propofol in ERCP. Material and methods: Sixty-one patients underwent ERCP (Group I: propofol, n = 31; Group II, sevoflurane, n = 30), with sedation controlled by the Ramsay sedation scale (RSS). The patients' demographic data, procedure length, overall drug dose, hemodynamic changes, duration of recovery and Aldrete scores during recovery were evaluated. In addition, satisfaction of the gastroenterologist was evaluated. Results: The mean sphincterotomy satisfaction scores were statistically significant (P= 0.043). The Aldrete scores and RSS of the groups were similar; there was a significant difference between groups at the beginning of the procedure regarding peripheric oxygen saturations and Group II's saturation levels increased during sedation. Conclusion: In ERCP, propofol infusion provides shorter recovery duration and adequate sedation levels. Sevoflurane and oxygen with a nasal mask can be chosen to generate specific anaesthesia in patients, especially for strong airway support and safety treating hypoxemic patients.

Results of genicular nerve ablation by radiofrequency in osteoarthritis-related chronic refractory knee pain

Background/aim: The aim of this study was to investigate the medium- to long-term effects of radiofrequency (RF) ablation of genicular nerves for chronic refractory knee pain due to osteoarthritis (OA). Materials and methods: Forty-eight patients who underwent RF ablation of the genicular nerves were evaluated retrospectively. The visual analogue scale (VAS) score, Western Ontario and McMaster universities osteoarthritis index (WOMAC index), opioid and nonsteroidal antiinflammatory drug (NSAID) use score, quality of life score, and treatment satisfaction score were examined at 1, 3, and 6 months after the procedure. Results: The mean VAS scores were significantly lower at the 1-, 3-, and 6-month evaluations compared with the preoperative values (P < 0.001). A significant decrease was observed in the WOMAC index compared with preoperative values (P < 0.001). It was found that 66.7% of opioid users and 56.3% of NSAID users stopped using medication. No serious complications were encountered during or after the procedure. Conclusion: In chronic refractory knee pain due to OA, the application of RF ablation to the genicular nerve is an effective and safe treatment option in the medium to long term.

Glass ionomer application for vocal fold augmentation: Histopathological analysis on rabbit vocal fold.

OBJECTIVES/HYPOTHESIS: The aim of this study was to investigate the use of glass ionomer cement (GIC) as an injection material for vocal fold augmentation and to evaluate the biocompatibility of the material. STUDY DESIGN: Ten adult New Zealand rabbits were used. METHODS: Under general anesthesia, 0.1-cc GIC was injected to one vocal fold and the augmentation of vocal fold was observed. No injection was applied to the opposite side, which was accepted as the control group. The animals were sacrificed after 3 months and the laryngeal specimens were histopathologically evaluated. RESULTS: The injected and the noninjected control vocal folds were analyzed. The GIC particles were observed in histological sections on the injected side, and no foreign body giant cells, granulomatous inflammation, necrosis, or marked chronic inflammation were detected around the glass ionomer particles. Mild inflammatory reactions were noticed in only two specimens. The noninjected sides of vocal folds were completely normal. CONCLUSION: The findings of this study suggest that GIC is biocompatible and may be further investigated as an alternative injection material for augmentation of the vocal fold. Further studies are required to examine the viscoelastic properties of GIC and the long-term effects in experimental studies. LEVEL OF EVIDENCE: NA.

The effect of esmolol on corrected-QT interval, corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients taking an angiotensin-converting enzyme inhibitor / Efeito de esmolol sobre o intervalo QT corrigido e alterações da dispersão do intervalo QT corrigido observadas durante a indução da anestesia em pacientes hipertensos que receberam um inibidor da enzima conversora de angiotensina / Efecto del esmolol sobre el intervalo QT corregido y alteraciones de la dispersión del intervalo QT corregido observadas durante la inducción de la anestesia en pacientes hipertensos que recibieron un inhibidor de la enzima convertidora de la angiotensina

BACKGROUND AND OBJECTIVES: The importance of minimizing the exaggerated sympatho-adrenergic responses and QT interval and QT interval dispersion changes that may develop due to laryngoscopy and tracheal intubation during anesthesia induction in the hypertensive patients is clear. Esmolol decreases the hemodynamic response to laryngoscopy and intubation. However, the effect of esmolol in decreasing the prolonged QT interval and QT interval dispersion as induced by laryngoscopy and intubation is controversial. We investigated the effect of esmolol on the hemodynamic, and corrected-QT interval and corrected-QT interval dispersion changes seen during anesthesia induction in hypertensive patients using angiotensin converting enzyme inhibitors. METHODS: 60 ASA I-II patients, with essential hypertension using angiotensin converting enzyme inhibitors were included in the study. The esmolol group received esmolol at a bolus dose of 500 mcg/kg followed by a 100 mcg/kg/min infusion which continued until the 4th min after intubation. The control group received 0.9% saline similar to the esmolol group. The mean blood pressure, heart rate values and the electrocardiogram records were obtained as baseline values before the anesthesia, 5 min after esmolol and saline administration, 3 min after the induction and 30 s, 2 min and 4 min after intubation. RESULTS: The corrected-QT interval was shorter in the esmolol group (p = 0.012), the corrected-QT interval dispersion interval was longer in the control group (p = 0.034) and the mean heart rate was higher in the control group (p = 0.022) 30 s after intubation. The risk of arrhythmia frequency was higher in the control group in the 4-min period following intubation (p = 0.038). CONCLUSION: Endotracheal intubation was found to prolong corrected-QT interval and corrected-QT interval dispersion, and increase the heart rate during anesthesia induction with propofol in hypertensive patients using angiotensin ...

JUSTIFICATIVA E OBJETIVO: É óbvia a importância de minimizar as respostas simpatoadrenérgicas exageradas e o intervalo QT e a dispersão do intervalo QT que podem ocorrer por causa de laringoscopia e intubação traqueal durante a indução da anestesia em pacientes hipertensos. Esmolol diminui a resposta hemodinâmica à laringoscopia e à intubação. Porém, o efeito de esmolol sobre a redução do intervalo QT prolongado e a dispersão do intervalo QT induzida pela laringoscopia e intubação é controverso. Pesquisamos o efeito de esmolol sobre a hemodinâmica e o intervalo QT corrigido e as alterações da dispersão do intervalo QT observadas durante a indução da anestesia em pacientes hipertensos que receberam inibidores da enzima conversora de angiotensina (IECA). MÉTODOS: Foram incluídos no estudo 60 pacientes, estado físico ASA I-II, com hipertensão arterial essencial e que receberam IECA. O grupo esmolol recebeu uma dose em bolus de 500 mcg kg-1, seguida por infusão contínua de 100 mcg kg-1 min-1 até o quarto minuto após a intubação. O grupo controle recebeu solução salina a 0,9%, semelhantemente ao grupo esmolol. Os valores da pressão arterial média e da frequência cardíaca e os registros do eletrocardiograma foram obtidos durante a fase inicial pré-anestesia, cinco minutos após a administração de esmolol e solução salina, três minutos após a indução e 30 segundos, dois minutos e quatro minutos após a intubação. RESULTADOS: O intervalo QT corrigido foi menor no grupo esmolol (p = 0,012), o intervalo de dispersão do intervalo QT corrigido foi maior no grupo controle (p = 0,034) e a frequência cardíaca média foi maior no grupo controle (p = 0,022) 30 segundos após a intubação. O risco da frequência de arritmia foi maior no grupo controle no quarto minuto após a intubação (p = 0,038). CONCLUSÃO: Descobrimos que a intubação traqueal prolonga o intervalo e a dispersão do intervalo QT corrigido e aumenta a frequência cardíaca durante a indução da ...

JUSTIFICACIÓN Y OBJETIVO: Es evidente la importancia que tiene minimizar las respuestas simpatoadrenérgicas exageradas y el intervalo QT y la dispersión del intervalo QT que pueden ocurrir a causa de la laringoscopia e intubación traqueal durante la inducción de la anestesia en pacientes hipertensos. El esmolol disminuye la respuesta hemodinámica a la laringoscopia y a la intubación. Sin embargo, su efecto sobre la reducción del intervalo QT prolongado y la dispersión del intervalo QT inducida por la laringoscopia e intubación es controvertido. Investigamos el efecto del esmolol sobre la hemodinámica y el intervalo QT corregido, y las alteraciones de la dispersión del intervalo QT observadas durante la inducción de la anestesia en pacientes hipertensos que recibieron inhibidores de la enzima convertidora de la angiotensina. MÉTODOS: Fueron incluidos en el estudio 60 pacientes, estado físico ASA I-II, con hipertensión arterial esencial y que recibieron inhibidores de la enzima convertidora de la angiotensina. El grupo esmolol recibió una dosis en bolos de 500 mcg/kg, seguida de infusión continua de 100 mcg/kg/min hasta el cuarto minuto después de la intubación.

Comparison of Four Different Supraglottic Airway Devices in Terms of Efficacy, Intra-ocular Pressure and Haemodynamic Parameters in Children Undergoing Ophthalmic Surgery.

OBJECTIVE: The aim of this study was to compare insertion parameters of four different types of supraglottic airway devices (SGAD) (Classic LMA, I-gel LMA, Proseal LMA, Cobra PLA) in children undergoing ophthalmic surgery and to determine the effect on intra-ocular pressure (IOP) and haemodynamic responses during insertion. METHODS: Sixty American society of Anesthesiologists (ASA) I-II children aged 1-10 years undergoing extra-ocular ophthalmic surgery were randomly divided into four groups (Group LMA, Group I-gel LMA, Group PLMA and Group CPLA) in this prospective, randomised study. Anaesthesia was induced with decreasing sevoflurane concentrations (8%-2%) in a mixture of 50% N2O-O2. All SGADs were inserted under deep anaesthesia. The characteristics of insertion (number of attempts, ease and time), oropharyngeal leak pressure (OLP) and complications were recorded. IOP in both eyes, heart rate (HR), mean arterial pressure (MAP) and EtCO2 were measured before and 2 and 5 min after insertion of the SGADs. RESULTS: There was no difference between the groups in terms of the characteristics of insertion. The mean IOP did not increase significantly in all groups. MAP and HR changes were similar among the groups during follow-up. In all groups, HR increased 2 min after insertion (statistically insignificant) and returned to the baseline value 5 min after insertion. A statistically significant correlation was seen between HR increase and IOP values before and after insertion of the SGADs (p=0.006, correlation coefficient=0.352). Desaturation was seen in one patient in Groups LMA, PLMA and CPLA, and laryngospasm was seen in two patients in Group CPLA and in one patient in Group LMA. CONCLUSION: It was seen that during insertion of Classic LMA, I-gel LMA, Proseal LMA and Cobra PLA, IOP did not increase and haemodynamic stability was maintained in children undergoing extra-ocular ophthalmic surgery.

The mean blood pressure, heart rate values and the electrocardiogram records were obtained as baseline values before the anesthesia, 5min after esmolol and saline administration, 3min after the induction and 30s, 2min and 4min after intubation. RESULTS: The corrected-QT interval was shorter in the esmolol group (p=0.012), the corrected-QT interval dispersion interval was longer in the control group (p=0.034) and the mean heart rate was higher in the control group (p=0.022) 30s after intubation. The risk of arrhythmia frequency was higher in the control group in the 4-min period following intubation (p=0.038). CONCLUSION: Endotracheal intubation was found to prolong corrected-QT interval and corrected-QT interval dispersion, and increase the heart rate during anesthesia induction with propofol in hypertensive patients using angiotensin converting enzyme inhibitors. These effects were prevented with esmolol (500mcg/kg bolus, followed by 100mcg/kg/min infusion). During induction, the blood pressure tends to decrease with esmolol where care is needed.

[Effects of ketamine and midazolam on emergence agitation after sevoflurane anaesthesia in children receiving caudal block: a randomized trial]. / Efeitos de cetamina e midazolam sobre a incidência de agitação pós-anestesia com sevoflurano em crianças submetidas ao bloqueio caudal: estudo randomizado.

BACKGROUND AND OBJECTIVES: Emergence agitation is a common postanaesthetic problem in children after sevoflurane anaesthesia. We aimed to compare the effects of ketamine and midazolam administered intravenously, before the end of surgery, for prevention of emergence agitation in children who received caudal block for pain relief under sevoflurane anaesthesia. METHODS: 62 American Society of Anesthesiologists patient classification status I children, aged 2-7 years, scheduled for inguinal hernia repair, circumcision or orchidopexy were enrolled to the study. Anaesthesia was induced with sevoflurane 8% in a mixture of 50% oxygen and nitrous oxide. After achieving adequate depth of anaesthesia, a laryngeal mask was placed and then caudal block was performed with 0.75mLkg(-1), 0.25% bupivacaine. At the end of the surgery, ketamine 0.25mgkg(-1), midazolam 0.03mgkg(-1) and saline were given to ketamine, midazolam and control groups, respectively. Agitation was assessed using Paediatric Anaesthesia Emergence Delirium scale and postoperative pain was evaluated with modified Children's Hospital of Eastern Ontario Pain Scale. RESULTS AND CONCLUSIONS: Modified Children's Hospital of Eastern Ontario Pain Scale scores were found higher in control group than in ketamine and midazolam groups. Paediatric Anaesthesia Emergence Delirium scores were similar between groups. Modified Children's Hospital of Eastern Ontario Pain Scale and Paediatric Anaesthesia Emergence Delirium scores showed a significant decrease by time in all groups during follow-up in postanaesthesia care unit. The present study resulted in satisfactory Paediatric Anaesthesia Emergence Delirium scores which are below 10 in all groups. As a conclusion, neither ketamine nor midazolam added to caudal block under sevoflurane anaesthesia did show further effect on emergence agitation. In addition, pain relief still seems to be the major factor in preventing emergence agitation after sevoflurane anaesthesia.

Comparison of reversal and adverse effects of sugammadex and combination of - Anticholinergic-Anticholinesterase agents in pediatric patients.

BACKGROUND: We aimed to compare clinical effects of sugammadex versus combination of anticholinergic-anticholinesterase agents for reversing of nondepolarizing neuromuscular block in pediatric patients. MATERIALS AND METHODS: A total of 60 pediatric patients whom should be performed general anesthesia in the supine position were enrolled to this randomized double-blinded clinical trial. Fentanyl 1 µg/kg, propofol 2 mg/kg, rocuronium 0.6 mg/kg were used in induction and sevofluran, 50% O2-50% N2O in maintenance of anesthesia. Neuromuscular conductions were assessed by train of four (TOF)-Watch SX (Organon, Schering-Plough, Ireland) acceleromyograph. Patients were intubated at the moment of TOF 0. At the end of the operation emergence of T2 point was replied by 2 mg/kg sugammadex administration in group 1 and 0.06 mg/kg neostigmine +0.02 mg/kg atropine in group 2. At the moment of T0.9 inhalation, gases were ceased, and patients were extubated. Hemodynamic alterations, access to T0.9, extubation time, recovery parameters, drug consumptions and adverse effects were recorded. RESULTS: Train of four scores showed a lesser increase in group 2 than group 1 from 15(th) s to 30(th) min during post reverse period (from 6.9 ± 6.4 to 91.7 ± 7.2 in group 2 vs. from 35.4 ± 21.4 to 99.5 ± 1.0 in group 1) (p < 0.0004). Group 1 patients exhibited much more complete muscle strength rates than group 2 (P < 0.001). T0.9 and extubation times were significantly longer in group 2 than group 1 (P < 0.001). Comparison of adverse effects yielded no difference. CONCLUSION: Sugammadex can be considered as a safe agent in order to reverse neuromuscular block in pediatric patients.

Comparison of analgesic efficacy of intravenous Paracetamol and intravenous dexketoprofen trometamol in multimodal analgesia after hysterectomy.

BACKGROUND: [corrected] We aimed to evaluate analgesic efficacy, opioid-sparing, and opioid-related adverse effects of intravenous paracetamol and intravenous dexketoprofen trometamol in combination with iv morphine after total abdominal hysterectomy. MATERIALS AND METHODS: Sixty American Society of Anesthesiologist Physical Status Classification I-II patients scheduled for total abdominal hysterectomy were enrolled to this double-blinded, randomized, placebo controlled, and prospective study. Patients were divided into three groups as paracetamol, dexketoprofen trometamol, and placebo (0.9% NaCl) due to their post-operative analgesic usage. Intravenous patient controlled analgesia morphine was used as a rescue analgesic in all groups. Pain scores, hemodynamic parameters, morphine consumption, patient satisfaction, and side-effects were evaluated. RESULTS: Visual Analog Scale (VAS) scores were not statistically significantly different among the groups in all evaluation times, but decrease in VAS scores was statistically significant after the evaluation at 12(th) h in all groups. Total morphine consumption (morphine concentration = 0.2 mg/ml) in group paracetamol (72.3 ± 38.0 ml) and dexketoprofen trometamol (69.3 ± 24.1 ml) was significantly lower than group placebo (129.3 ± 22.6 ml) (P < 0.001). Global satisfaction scores of the patients in group placebo was significantly lower than group dexketoprofen trometamol after surgery and the increase in global satisfaction score was significant only in group placebo. CONCLUSION: Dexketoprofen trometamol and Paracetamol didn't cause significant change on pain scores, but increased patients' comfort. Although total morphine consumption was significantly decreased by both drugs, the incidence of nausea and vomiting were similar among the groups. According to results of the present study routine addition of dexketoprofen trometamol and paracetamol to patient controlled analgesia morphine after hysterectomies is not recommended.

The efficacy of intravenous paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children.

STUDY OBJECTIVE: To evaluate the efficacy and the quality of recovery with intravenous (IV) paracetamol versus tramadol for postoperative analgesia after adenotonsillectomy in children. DESIGN: Prospective, randomized, double-blinded clinical trial. SETTING: Operating room and Postanesthesia Care Unit (PACU) of a university-affiliated hospital. PATIENTS: 64 ASA physical status I and II children, aged 6 to 16 years, scheduled for adenotonsillectomy. INTERVENTIONS: All patients were premedicated with oral midazolam 0.5 mg/kg 30 minutes before surgery. Patients were randomized to two groups following induction of general anesthesia. The paracetamol group (n = 32) received 15 mg/kg of IV paracetamol and the tramadol group (n = 32) received 1.0 mg/kg of IV tramadol. MEASUREMENTS: Modified Hannallah pain scores, emergence agitation, Aldrete scores, sedation scores, time to first administration of analgesic, heart rate, and mean arterial blood pressure were recorded for each patient. Data were recorded every 5 minutes for the first 30 minutes and every 10 minutes for the remaining 30 minutes in the PACU, then at 2, 3, 4, 5, 6, 8, 12, and 24 hours in the ward. The frequency of postoperative nausea and vomiting also was noted. Satisfaction of parents and nurses was determined on a 4-point scale at the end of the study. MAIN RESULTS: No significant demographic differences between groups were noted. No statistically significant difference was found in postoperative pain scores in either group. Agitation scores, Aldrete scores, sedation scores, and number of patients who received rescue analgesia and time to administration of rescue analgesia were similar in both groups. CONCLUSIONS: The IV formulation of paracetamol was associated with similar analgesic properties and early recovery to that of IV tramadol after adenotonsillectomy in children.

Cardiac arrest after intracisternal papaverine instillation during intracranial aneurysm surgery. Case report.

Cerebral vasospasm induced by aneurysmal subarachnoid hemorrhage is still a leading cause of morbidity and death. This 50-year-old man underwent surgery for aneurysm clipping. After the aneurysm was clipped, papaverine was instilled into the surgical area. Bradycardia, hypotension, and sinus arrest developed in the first minute after applying the papaverine. Thus, the authors concluded that the application of papaverine to the surgical area can result in fatal bradycardia and hypotension.

Bilateral extraoral, infraorbital nerve block for postoperative pain relief after cleft lip repair in pediatric patients: a randomized, double-blind controlled study.

The objective of this study was to evaluate the effectiveness of bilateral extraoral infraorbital nerve block with 0.25% bupivacaine administered at the end of surgery in postoperative pain relief after cleft lip repair. Forty ASA I-II children were randomly divided into 2 groups. Group I received 1.5 mL 0.25% bupivacaine and group II received 1.5 mL saline. FLACC scores of the patients in the recovery room in group I were 4 times less than in group II (P = 0.001) and in the first 4 hours postoperatively were apparently less in group I (P = 0.001). Mean time to first paracetamol requirement was longer in group I (P = 0.001). Total paracetamol consumption was lower in group I (P = 0.001). None of the patients required rescue tramadol in group I, whereas all patients in group II needed. In group I, parent satisfaction scores were higher (P = 0.001). Vomiting incidence was higher in group II (P = 0.028). Bilateral extraoral, infraorbital nerve block administered at the end of surgery provides satisfactory analgesia with high parental satisfaction and lower complication rates and reduces rescue analgesic consumption in patients undergoing repair of cleft lip.

Effect of lornoxicam on postoperative analgesia after myomectomy.

BACKGROUND: In this prospective, randomized study, we evaluate the postoperative analgesic effect of lornoxicam after myomectomy operations. MATERIAL-METHOD: Forty ASA I-II patients scheduled for myomectomy operation were enrolled to this study. Patients were randomly divided into two groups and epidural block was performed with 0,75 % ropivacaine. After the operation, morphine Patient Controlled Epidural Analgesia (PCEA) combined with placebo (saline 2 ml iv) and morphine PCEA combined with lornoxicam 8 mg iv were administered to patients in Group I and Group II, respectively. Pain was assessed at the 0,1st, 2nd, 4th, 6th, 8th, 12th and 24th hours postoperatively. Chi-square and student's t tests were used for statistical analysis. RESULTS: VAS( Visual Analog Scale) scores were higher in Group I than Group II at 2nd, 4th, 6th and 24th hours. Total morphine consumption was 10.45+/- 4.03 in Group I and 4.25 +/- 1.74 in Group II. CONCLUSION: Single dose iv lornoxicam is a safe and an effective treatment option of post-myomectomy pain as it produces effective analgesia, reduces morphine consumption and does not increase the side effects.

The effect of opioid administration by different routes on the psychological functions of elderly patients.

Psychological status of patients during epidural and intravenous (i.v.) morphine administration are not known enough. It's known that after administration of morphine epidurally and intravenously plasma concentrations are similar but the concentrations in cerebrospinal fluide are different. The effects of two postoperative analgesia treatment regimens on the psychological and mental functions of the elderly after major orthopedic surgery were investigated in this randomized, blinded study. Morphine was used epidurally in Group E and intravenously in Group IV with patient controlled analgesia method for postoperative analgesia treatment. All patients were assessed for psychological status the day before surgery and 2 days after surgery using the Brief Symptom Inventory (BSI). The results of the BSI were assessed with the Global Severity Index (GSI). Nine subscales were also derived: depression, somatization, obsessive-compulsive, anxiety, interpersonal sensitivity, hostility, phobic anxiety, paranoid ideation, and psychoticism. There was not significant difference between the groups for preoperative and postoperative GSI results (p>0.05). Only interpersonal sensitivity subscale results in Group i.v. were decreased compared to the baseline (p<0.001). Preoperative BSI and submeasurement test scores revealed no correlation with total morphine consumption in both groups (p>0.05). Mental changes like agitation, time and place disorientation were seen equally in both groups. This study showed that after epidural and intravenouse morphine administration, no psychologycal changes were observed in the postoperative period compared with baseline. Patients who received morphine intravenously were showed less interpersonal sensitivity in the postoperative period.

The protective effects of intravenous anesthetics and verapamil in gut ischemia/reperfusion-induced liver injury.

BACKGROUND: We investigated the protective effects of IV anesthetics and verapamil in gut ischemia/reperfusion-induced liver injury. METHODS: Forty male Wistar Albino rats were randomly assigned to four groups of 10 rats each. Anesthesia was induced and maintained with propofol in Groups 1 and 3 and with thiopental in Groups 2 and 4 during the experiment. All animals developed intestinal ischemia after occlusion of the superior mesenteric artery for 30 min. Reperfusion was induced by removal of the microvascular clamp and was allowed to continue for 120 min. The animals in Groups 3 and 4 were given verapamil 10 min before reperfusion. Liver and ileum samples were taken for measurement of malondialdehyde (MDA) and histopathologic examination before ischemia and 30 and 120 min after reperfusion. Blood samples were also obtained for measurement of plasma tumor necrosis factor-alpha and interleukin-6 levels. RESULTS: Gut ischemia/reperfusion-induced significant increases in MDA contents of liver and gut and serum cytokines, consistent with histopathologic injury scores. Propofol effectively stabilized the MDA levels and decreased the tissue injury scores of the liver and gut. Tumor necrosis factor-alpha and interleukin-6 levels increased less in the propofol groups than in the thiopental groups. There was no additive preventive effect of verapamil on propofol. The addition of verapamil to thiopental was effective in decreasing the serum cytokines and liver MDA content. CONCLUSION: Propofol may offer advantages by inhibiting lipid peroxidation and inflammatory cytokine production in an animal model of gut ischemia/reperfusion-induced liver injury.

Efficacy of lornoxicam in postoperative analgesia after total knee replacement surgery.

In total knee replacement operation, patients have a severe pain in the postoperative period. Because of side effects of opioids, multiple postoperative pain treatment regimens are more suitable in these elderly patients. In this double-blind, randomized, placebo controlled study, the effect of lornoxicam administration (32 mg/48 hour) on morphine consumption and drug-related side effects were investigated in elderly patients undergoing total knee replacement. Group M (n=23) and Group L (n=23) received morphine with patient controlled analgesia (PCA) device postoperatively. Additionally Group L received lornoxicam 16 mg intravenously 15 minutes before surgery and 8 mg at postoperative 12th and 24th hours. Morphine consumption in Group L were significantly lower than in Group M at 2, 3, 6, 8, 24, 36 and 48th postoperative hours (p<0.05). At the end of 48th hour mean total morphine consumptions (mean+/-SD) for Group M and Group L were 63.70+/-15.70 mg and 34.60+/-16.32 mg, respectively. AUC (area under the curve) Morphine 0-48h in Group M was 59+/-13 and in Group L it was 30+/-13 (p<0.001). Incidence of side effects in Group M were 60% and 25% in Group L (p<0.05). In Group M, 8 patients (40%) experienced nausea and 3 (15%) patients experienced itching where as in Group L, 3 patients (15%) experienced nausea, 1 patient (5%) itching, 1 patient (5%) dry mouth. Lornoxicam administration in total knee replacement is associated with decreased morphine consumption for postoperative analgesia and fewer side effects.

The effect of 3-in-1 femoral nerve block with ropivacaine 0.375% on postoperative morphine consumption in elderly patients after total knee replacement surgery.

Total knee replacement (TKR) is one of the most painful orthopedic surgical procedures. This study was aimed to investigate the effect of a single-shot preoperative 3-in-1 femoral nerve block on postoperative pain by using 0.375% ropivacaine, and on the consumption of morphine by using PCA following the TKR surgery. Side effects were also evaluated in this setting. 34 patients were included in this study. Group R (n=17) received a 3-in-1 femoral nerve block (FNB) with 40 mll of ropivacaine 0.375%. Group S (n=17) received only a 2 mg loading dose of morphine 30 minutes before the end of surgery, and no block was performed. Both groups received general anesthesia and postoperatively had a PCA pump programmed to deliver morphine. VAS scores at rest, morphine consumption and adverse effects were recorded. Two patients were excluded from each group. Pain scores at 0, 1, 2, 3, 4, 6, 8 postoperative hours were significantly lower in group R in resting position (p<0.05). Group R experienced no pain at the recovery room and this state lasted 8 hours after the surgery while group S reached the acceptable score (VAS ? 3) one hour after leaving the recovery room. The morphine requirement was significantly lower in Group R at 12, 18, 24, 48 hr after TKR (p<0.001). Side effects were also lower in this group. Preoperative single-shot 3-in-1 FNB with 40 cc of ropivacaine 0.375% provides better VAS scores, less morphine consumption and fewer side effects in elderly patients when compared to the group with no block.
