A comparison of the effects of thoracolumbar interfascial plane (TLIP) block and erector spinae plane (ESP) block in postoperative acute pain in spinal surgery.

PURPOSE: Spinal surgeries are a very painful procedure. New regional techniques for postoperative pain management are being considered. The present study aimed to evaluate the hypothesis that the ultrasound-guided erector spinae plane (ESP) block would lead to lower opioid consumption compared to the thoracolumbar interfascial plane (TLIP) block after lumbar disk surgery. The study's primary objective was to compare postoperative total opioid consumption, and the secondary objective was to assess postoperative pain scores. METHODS: Sixty-eight patients who underwent elective lumbar disk surgery were randomly assigned to either the ESP block group or the TLIP block group. The current pain status of the patients in both the ESP and TLIP block groups was assessed using the Numerical Rating Scale (NRS) at specific time intervals (30 min, 1, 6, 12 and 24 h) during the postoperative period. The number of times patients administered a bolus dose of patient-controlled analgesia, (PCA) within the first 24 h was recorded. RESULTS: In the ESP group, the total opioid consumption in terms of morphine equivalents was found to be significantly lower (ESP group: 7.7 ± 7.0; TLIP group: 13.0 ± 10.1; p < 0.05). The NRS scores were similar between the groups at 30 min, 1, 6, and 12 h, but at 24 h, they were significantly lower in the ESP group. Moreover, the groups had no significant difference regarding observed side effects. CONCLUSION: This study demonstrated the analgesic efficacy of both techniques, revealing that the ESP block provides more effective analgesia in patients undergoing lumbar disk surgery.

May the first-line treatment for foreign body aspiration in childhood be flexible bronchoscopy?

INTRODUCTION: Rigid bronchoscopy (RB) is the traditional treatment in foreign body (FB) aspiration in childhood but is a traumatic and invasive procedure. However, flexible optic bronchoscopy (FoB) is a noninvasive and nontraumatic respiratory intervention. The aim of this study was to evaluate FoB as a first-line treatment modality in pediatric cases presenting with a preliminary diagnosis of FB aspiration. METHODS: Subjects who underwent FoB under general anesthesia with the preliminary diagnosis of FB aspiration were enrolled in this cross-sectional study. Two cases were inherited from pediatric surgery because they were not removed with FoB. The demographic, clinical, and radiological findings at the presentation were recorded. Results of success rate and complications were recorded. RESULTS: Among the FB aspiration cases age range of 7 months to 16 years. FoB demonstrated a FB in the airways of 31 (62.2%) subjects. The duration of the symptoms in the subjects was 9.1 ± 8.8 days. Three of the cases were taken over from pediatric surgery because they were not removed with RB. Most commonly encountered FB's were organic materials (n = 20, 64%). FoB was successful in removing the FB from the proximal and also distal airways in 93% of the subjects. No significant complications and side effects were observed except post-FoB cough. CONCLUSION: This result has shown that FoB for the treatment of FB aspiration is successful in removing FB aspiration from both the proximal and distal airway that the RB cannot remove. Furthermore, FoB did not have any significant airway complication. FoB may be used as the first-line treatment modality for FB aspiration instead of RB in childhood the fact that noninvasive and nontraumatic respiratory intervention.

Two different methods of lidocaine inhalation before diagnostic flexible bronchoscopy: effects on post-bronchoscopy respiratory symptoms

Background/aim: Use of topical anesthesia before flexible bronchoscopy for the evaluation of the upper airways prevents cough and stridor during and after the procedure while reducing the need for sedation. In practice, lidocaine is the medication of choice before bronchoscopy. There various types of nebulizers used for inhalation treatments. In this study, we compared the respiratory tract symptoms after flexible bronchoscopy between children who received pre-procedure topical lidocaine with mesh or jet nebulizers. Materials and methods: We enrolled 4­18 years old subjects that underwent flexible bronchoscopy due to treatment-resistant asthma in this retrospective case-control study. Twenty subjects received topical lidocaine with jet nebulizers while 20 received it with mesh nebulizers. Age, sex, duration of bronchoscopy, duration of anesthesia, time to awaken, and time to recovery were recorded as well as cough and laryngospasm scores after flexible bronchoscopy. Results: Severe cough after flexible bronchoscopy was not encountered in the mesh nebulizers group but was seen in 10% of the jet nebulizers group (p = 0.027). On the other hand, age, sex, duration of bronchoscopy, duration of anesthesia, time to awaken, and time to recovery were not significantly different between the mesh and jet nebulizer groups (p = 0.44, 0.34, 0.51, 0.88, 0.88, and 0.22, respectively). Moreover, croup and laryngospasm scores between the two groups were similar (p = 0.62, 0.50 respectively). Cough score was significantly worse jet nebulizers group (p = 0.03). Conclusion: Topical lidocaine application with mesh nebulizers decreases the most common complication, cough, after flexible bronchoscopy in children more effectively compare to jet nebulizers. Thus, mesh nebulizers may be a faster way of nebulization before flexible bronchoscopy as an alternative to jet nebulizers.

Isolation and in vitro cultivation of human urine-derived cells: an alternative stem cell source.

OBJECTIVE: For in vitro tissue engineering in urology, stem cells are commonly isolated from tissue specimens obtained during open or endoscopic surgery. Within the context of the present study our aim was to isolate cells from human urine by an alternative and safe technique rather than using the indicated method. MATERIAL AND METHODS: After human urine samples had been collected from young and healthy donors via urethral catheterization, cells were precipitated by centrifugation and cultured. Following this isolation procedure, cells were characterized by immunocytochemical method using specific antibodies. RESULTS: When these cells were characterized by immunocytochemical methods using specific antibodies some of them were positive for mesenchymal stem cell marker CD90 while the others were labelled with urothelial marker cytokeratin 7. When all these results were taken into consideration, urothelial cells together with stem cells were observed in the urine- derived cell population. CONCLUSION: According to the results obtained from this study human urine may be preferred as an alternative stem cell and urothelial cell source in that this method is and easily reproducible non-invasive method.

Effects of low-dose propofol vs ketamine on emergence cough in children undergoing flexible bronchoscopy with sevoflurane-remifentanil anesthesia: a randomized, double-blind, placebo-controlled trial.

STUDY OBJECTIVE: To determine the effects of low-dose ketamine and propofol on cough during emergence and the recovery period when administered at emergence in children undergoing fiberoptic bronchoscopy for bronchoalveolar lavage (FOBL) with sevoflurane-remifentanil anesthesia. DESIGN: Randomized, double-blind, placebo-controlled trial. SETTING: Operating room, postoperative recovery area. PATIENTS: Sixty-eight children aged 1 to 8 years old undergoing elective diagnostic FOBL. INTERVENTIONS: After discontinuation of anesthetics at the end of FOBL, patients were randomly divided into 3 groups: in group K, children were administered 0.5 mg/kg of ketamine; in group P, 0.5 mg/kg of propofol; and in group C, 0.1 mL/kg of normal saline. MEASUREMENTS: Anesthesia time, procedure time, emergence time, and recovery time were recorded. Coughing and delirium scores were recorded as the patient fully emerged from anesthesia (time 0) and 5, 10, 15, and 20 minutes later. MAIN RESULTS: The percentage of children with moderate or severe cough during emergence was similar in all groups. Mean delirium scores at emergence (T0) were significantly lower in group K than those in group P and in group C (P = .0001 and P = .02). Mean delirium score at 5 minutes in group K (6 [5-10]) was significantly lower than that of group C (P = .02) and similar to that of group P. The recovery time of group K was significantly longer than that of group C and group P (P = .01 and P = .03, respectively). CONCLUSIONS: Ketamine or propofol given at the end of sevoflurane-remifentanil general anesthesia in children undergoing FOBL did not decrease cough more than normal saline during the emergence period. Ketamine and propofol, compared to normal saline, had a beneficial effect on decreasing the incidence of emergence delirium. Ketamine lengthened recovery time.

The Efficacy of Femoral Block and Unilateral Spinal Anaesthesia on Analgesia, Haemodynamics and Mobilization in Patients undergoing Endovenous Ablation in the Lower Extremity.

OBJECTIVE: This study aimed to investigate the efficacy of femoral block and unilateral spinal anaesthesia on analgesia, haemodynamics and mobilization during endovenous ablation in patients with lower extremity venous insufficiency. METHODS: Forty patients of ASA physical status I and II, with ages ranging between 30 and 45 years, and who were scheduled for endovenous laser ablation for varicose veins were prospectively enrolled in this study. Patients were randomized into a unilateral spinal anaesthesia group (group HS, n=20) or a femoral block group (group F, n=20). Group HS received 7.5-10 mg of heavy bupivacaine for unilateral spinal anaesthesia, while group F received 100 mg prilocaine for femoral block with ultrasound guidance. The level of motor blockage (Bromage score), visual pain score, mean heart rate and mean arterial pressures were recorded at postoperative 0, 1, 2, 3d and 6 h, respectively. RESULTS: Perioperative visual pain score values in both groups were <4. None of the groups required an additional analgesic agent. Bromage scores were significantly lower in group F than in group HS during the postoperative period (p<0.01). Motor function returned to normal in all patients at 3 h in group F and at 6 h in group HS. Postoperative mean heart rate and arterial pressure did not differ between the groups (p>0.05). CONCLUSION: In patients with lower extremity venous insufficiency who were undergoing endovenous laser ablation, an ultrasound-guided femoral block provided similar analgesia with that of unilateral spinal anaesthesia. In group F, the duration of anaesthesia and mobilization time was shorter.

[Comparison of thoracic epidural and paravertebral analgesia for postoperative pain control after thoracotomy]. / Torakotomi sonrasi postoperatif agri kontrolünde torakal epidural ve paravertebral blogun karsilastirilmasi.

OBJECTIVES: In the present randomized, controlled, and blinded study, the effects of thoracic paravertebral analgesia were compared to those of epidural analgesia on postoperative pain, hemodynamics, and respiration rate following thoracotomy. METHODS: Patients scheduled for elective open-lung surgery were included. One hour prior to surgery, thoracic epidural catheters were used in 18 patients (ED group), and ultrasound-guided paravertebral catheters were used in 17 patients (PV group). Standard general anesthesia was administered to all. Following anesthesia, postoperative analgesia of levobupivacaine 0.1% and morphine 0.1 mg mL-1 was administered via catheter. Patient-controlled analgesia (PCA) regime with tramadol was initiated, and amounts of local anesthetics and tramadol demanded and delivered within the first 24 hours were recorded. Visual analog scale (VAS) pain score, sedation score, side effects, and vital signs (blood pressure, heart rate, and respiratory rate) were assessed by an observer blinded to patient data at 1, 2, 3, 4, 6, 12, and 24 hours. RESULTS: Differences in PCA bolus demands and deliveries were not statistically significant between the PV group (26.8±1.3 and 33.1±4.5) and the ED group (25.1±3.5 and 32.5±4.3). Neither were differences in VAS scores statistically significant (p=0.3). Rates of sedation among the PV group were lower than those of the ED group at 1 hour (p=0.001). Five patients in the ED (%28) group experienced hypotension (p=0.02). CONCLUSION: Paravertebral block with levobupivacaine 0.1% and morphine 0.1 mg mL-1 may be an alternative form of pain relief following thoracotomy.

The Effect of Flexible Bronchoscopy on Anxiety in Children.

OBJECTIVES: Flexible bronchoscopy (FB) is a semi-invasive diagnostic tool that allows direct visualization of the airways. The use for diagnostic and therapeutic purposes in children is incrasing with the developments in modern anesthesia. Irrespective of the type of the invasive diagnostic procedure, these interventions are known to cause anxiety in patients. The aim of our study was to evaluate the anxiety and depression status in children hospitalized for bronchoscopy and to investigate the effects of FB. MATERIAL AND METHODS: Thirty children hospitalized for FB and 30 controls, aged 7 to 16 years, were enrolled in this study. Anxiety was evaluated with the "Hospital anxiety and depression scale" (HADS)" besides other parameters recorded. RESULTS: The mean HADS anxiety scores in the patient and control groups were respectively 10.1 (3.5) and 2.7 (1.3) (p= 0.001). The mean HADS depression scores were respectively 8.8 (3.7) and 2.2 (1.1) (p= 0.001). Among the patients, 50% had anxiety and 53.3% had findings while none in the control group showed signs of anxiety and depression. A positive correlation was found between the age and, anxiety and depression scores in patients' groups (respectively r1= 0.257; p= 0.05 and r2= 0.288; p= 0.02). CONCLUSION: Anxiety was demonstrated in nearly half of the children hospitalized for bronchoscopy. It has been observed that behavioral and physical problems may be encountered in approximately 40-60% of children who feel generalized anxiety before anesthesia, during the preoperative, postoperative period, and subsequent periods. These results suggest that the detection of children with increased anxiety and indicate the individual requirements can be assisted pharmacological and psychological supports.

Thromboelastography in the evaluation of coagulation disorders in patients with sepsis.

AIM: Unbalanced hemostasis and disseminated intravenous coagulopathy serve as key participants in organ dysfunction and disability. In this study we evaluated the coagulation profiles of patients diagnosed with systemic inflammatory syndrome (SIRS)-sepsis and multiple organ dysfunction syndrome. We also researched coagulation in sepsis by comparing thromboelastography (TEG) data with those of nonsepsis patients to determine the usefulness of the TEG device. MATERIALS AND METHODS: Data were collected from 55 anesthesiology and surgery intensive care unit (ICU) patients: 21 with SIRS-sepsis (Group S) and 34 patients without SIRS-sepsis (Group C). Blood samples were taken upon admission to the ICU (t1) and on day 3 of the ICU stay (t2). TEG data (R = reaction time, K = coagulation time, a = alpha angle, and MA = maximum amplitude) were recorded. TEG parameters were compared with routine coagulation and hemogram studies. RESULTS: The mean R value in Group C was higher than that of Group S at both t1 and t2. Group S had a significantly lower K value and higher alpha angle at t1 compared to Group C (P < 0.05). CONCLUSION: Hypercoagulability was observed in SIRS-sepsis patients in the ICU, as measured with TEG. We believe that TEG will be a useful tool in the evaluation of coagulation disorders developing in septic critically ill patients.

Ultrasound guided posterior femoral cutaneous nerve block.

The posterior femoral cutaneous nerve (PFCN) is a branch of the sacral plexus. It needs to be implemented as a complementary block for anesthesia or in the surgeries necessitating tourniquet in the suitable cases. We consider target oriented block concept within the PFCN block in the anesthesia implementations with the emergence of ultrasonic regional anesthesia in the practice and with the better understanding of sonoanatomy.

The effects of lornoxicam on neuroprotection following diffuse traumatic brain injury in rats.

AIM: In this study, the effects of lornoxicam on the prevention of secondary brain injury via the apoptotic pathway were studied in a rat model of head injury. MATERIAL AND METHODS: Thirty adult male Wistar albino rats were anesthetized, and experimental closed head trauma was induced by allowing a 450 g weight to fall two meters onto a metallic disk fixed to the intact skull. After head injury, the rats were randomly divided into two groups: Group I (n=15) rats were administered 2 mL saline intraperitoneally (controls); Group II (n=15) rats were administered 2 mL 1.3 mg kg-1 lornoxicam intraperitoneally. Brain tissue samples were divided into two pieces by interhemispheric incision for biochemical and histological analysis. RESULTS: TUNEL positivity was seen in neuroglia cells of the brain cortex in both groups. While the immunoreactivities of caspase 8, 9 and Fas/ Fas ligand were similar in both groups, the immunoreactivity of caspase 3 was greater in Group I than Group II. MDA was significantly lower in Group II than in Group I (p < 0.05). The decrease in SOD level was higher in Group I than Group II. CONCLUSION: Lornoxicam did not prevent apoptosis in this rat model of brain trauma but causes a decrease.

The effects of lornoxicam on brain edema and blood brain barrier following diffuse traumatic brain injury in rats.

BACKGROUND: In this experiment, the effects of lornoxicam on brain edema and the blood brain barrier (BBB) following diffuse traumatic brain injury (TBI) were studied. METHODS: Twenty adult male Wistar albino rats were anesthetized, and experimental closed head trauma was induced by the Marmarou method. After head injury, the rats were randomly divided into two groups: Group I was the control group, to which 2 ml saline was administered intraperitoneally, and Group II was the lornoxicam group, to which 2 ml 1.3 mg kg-1 lornoxicam was administered intraperitoneally. Twenty-four hours after head trauma, 99 mTc pentetate (DTPA) was injected at a dose of 37 MBq, and posterior planar images of each rat were obtained using an Infinia gamma camera. After imaging of BBB permeability, brain tissues were dissected from the cranium. The brain water content (BWC) of each sample was calculated using the wet-dry method. RESULTS: The lesion/background (L/b) ratio of Group I was 3.76±0.46 and 3.02±0.66 for early (5th min) and late (60th min) imaging, respectively. In Group II, the L/b ratios were 3.52±0.96 and 2.63±0.63 for early and late imaging, respectively (p>0.05). BWC was 79.6±2.5% and 77.5±1.1% for Groups I and II, respectively (p<0.05). CONCLUSION: In this rat model of TBI, lornoxicam reduced brain edema but did not affect BBB permeability.

Which implant is better for treating reverse obliquity fractures of the proximal femur: a standard or long nail?

BACKGROUND: Reverse obliquity fractures of the proximal femur have biomechanical characteristics distinct from other intertrochanteric fractures and high implant failure rate when treated with sliding hip screws. Intramedullary hip nailing for these fractures reportedly has less potential for cut-out of the lag screw because of their loadbearing capacity when compared with extramedullary implants. However, it is unclear whether nail length influences healing. QUESTIONS/PURPOSES: We compared standard and long types of intramedullary hip nails in terms of (1) reoperation (fixation failure), (2) 1-year mortality rate, (3) function and mobility, and (4) union rate. METHODS: We conducted a pilot prospective randomized controlled trial comparing standard versus long (≥ 34 cm) intramedullary hip nails for reverse obliquity fractures of the proximal femur from January 2009 to December 2009. There were 15 patients with standard nails and 18 with long nails. Mean age was 79 years (range, 67-95 years). We determined 1-year mortality rates, reoperation rates, Parker-Palmer mobility and Harris hip scores, and radiographic findings (fracture union, blade cut-out, tip-apex distance, implant failure). Minimum followup was 12 months (mean, 14 months; range, 12-20 months). RESULTS: We found no difference in reoperation rates between groups. Two patients (both from the long-nail group) underwent revision surgery because of implant failure in one and deep infection in the other. There was no difference between the standard- and long-nail groups in mortality rate (17% versus 18%), Parker-Palmer mobility score (five versus six), Harris hip score (74 versus 79), union rate (100% in both groups), blade cut-out (zero versus one), and tip-apex distance (22 versus 24 mm). CONCLUSIONS: Our preliminary data suggest reverse obliquity fractures of the trochanteric region of the femur can be treated with either standard or long intramedullary nails.

[Comparison of clinical effectiveness of thoracic epidural and intravenous patient-controlled analgesia for the treatment of rib fractures pain in intensive care unit]. / Toraks travmali hastalarda intravenöz hasta kontrollü analjezi ile torakal epidural hasta kontrollü analjezinin klinik etkinliginin karsilastirilmasi

BACKGROUND: The results of thoracic epidural and systemic patient controlled analgesia practice were evaluated retrospectively in patients with thoracic trauma. METHODS: Patients who were admitted to the intensive care unit between 1997 and 2003, with a diagnosis of multiple rib fractures related to thoracic trauma were evaluated retrospectively. Data were recorded from 49 patients who met the following criteria; three or more rib fractures, initiation of PCA with I.V. phentanyl or thoracic epidural analgesia with phentanyl and bupivacaine. RESULTS: There were no significant differences between the groups concerning injury severity score. APACHE II score (8.1+/-1.6 and 9.2+/-1.7) and the number of rib fractures (4+/-1.1 and 6.8+/-2.7) were higher in thoracic epidural analgesia group (p<0.05). Pain scores of patients who received thoracic epidural analgesia were significantly lower as from 6th hour during whole therapy (p<0.05). Length of intensive care unit stay (15.6+/-5.9 and 12.1+/-4.4 day) was found to be shorter in thoracic epidural analgesia group (p<0.05). There were no differences between the groups regarding mechanical ventilation requirement, pulmonary and cardiac complications. CONCLUSION: We suggest that the use of thoracic epidural analgesia with infusion of local anesthetics and opioids are more appropriate as they provide more effective analgesia and shorten length of intensive care unit stay in chest trauma patients with more than three rib fractures who require intensive care.

The effect of Misoprostol, a prostaglandin E1 analog, on apoptosis in ischemia-reperfusion-induced intestinal injury.

The aim of this study was to investigate whether Misoprostol, a synthetic prostaglandin (PG) E1 analog, has any effect on the prevention of apoptosis in ischemia-reperfusion (I/R)-induced intestinal injury. Thirty adult male Wistar albino rats were divided into three groups: group I=sham operated+saline; group II=I/R+saline; and group III=I/R+Misoprostol. Misoprostol (50microg/kg/d) was administered as an intragastric meal for 3 days. The terminal ileum was collected for histological and biochemical investigations. Apoptotic cells were detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end-labelled (TUNEL) reaction. Immunohistochemical analysis was performed to determine the distribution of inducible nitric oxide synthase (iNOS) and endothelial NOS (eNOS). Samples were also analyzed for malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). The number of TUNEL-positive cells was higher in group II when compared to the other two groups (p<0.05). In group III this value was higher when compared to group I, but lower than group II (p<0.05). iNOS immunoreactivity was not detected in ileum sections of group I animals, but moderate immunoreactivity was seen in group II and mild immunoreactivity in group III. The immunoreactivity of eNOS was moderate in ileum sections of all three groups. In ileum tissue, MDA was found to be higher in group II compared to group I (p<0.05), but there was no difference in group III. SOD was not different between groups I and III, but was significantly higher in group II (p<0.05). In our experimental model of I/R-induced intestinal injury, apoptosis is induced in enterocytes, whereas Misoprostol decreases enterocyte apoptosis in this experimental model. Our results indicate that Misoprostol may play a key role in the pathophysiologic events leading to failure of the intrinsic gut barrier defense mechanisms of intestinal epithelium.

Comparison of analgesic activity of the addition to neostigmine and fentanyl to bupivacaine in postoperative epidural analgesia.

OBJECTIVE: To compare the analgesic and side effects of bupivacaine in combinations with neostigmine and fentanyl using patient-controlled-epidural analgesia (PCEA) methods in the postoperative period after abdominal hysterectomy. METHODS: Seventy-five adult American Society of Anesthesiologists physical status I-II patients, aged 18-65 years were included in the study. The study took place in Celal Bayar University Hospital, Turkey between 2003-2004 years. After preoperative epidural catheterization, the patients were operated under general anesthesia. After surgery, the patients were randomly allocated in a double-blinded manner to receive PCEA and divided into 3 groups: Group B: 0.125% bupivacaine, Group N: 0.125% bupivacaine plus neostigmine 4 ug kg-1 and Group F: 0.125% bupivacaine plus 1 ug kg-1 fentanyl solutions (10 mL loading dose, 5 mL bolus dose, 10 min lockout time, 30 mL in 4 hour limit). During the following 24 hours, hemodynamic parameters, pain score using visual analog scale, total analgesic consumption, additional analgesic requirements, sedation, satisfaction, nausea scores and probable side-effects were evaluated. RESULTS: Total analgesic consumption was 143.7 +/- 7.2 mL in Group B, 123.4 +/- 6.2 mL in Group N and 106 +/- 8.3 mL in Groups F. The mean value in Group F was significantly lower than Group N and Group B (p<0.05), and was lower in Group N than Group B. Visual analog scale scores were lower in Group F than other groups (p<0.05). There were no differences in side effects between all groups. CONCLUSION: Fentanyl and neostigmine by the PCEA method can be used safely for postoperative analgesia after gynecologic surgery. They increase analgesia quality and satisfaction without an increase in side effects.

The effects of tramadol and fentanyl on gastrointestinal motility in septic rats.

In this study, we investigated the effects of tramadol and fentanyl on gastrointestinal transit (GIT) during acute systemic inflammation in an experimental model of cecal ligation and perforation (CLP). One-hundred-twenty male Swiss-Albino rats were divided randomly into 6 groups: Group I = sham-operated + saline; Group II = sham-operated + fentanyl; Group III = sham-operated + tramadol; Group IV = CLP + saline; Group V = CLP + fentanyl; Group VI = CLP + tramadol. Suspension of charcoal was administered as an intragastric meal to measure the GIT. GIT% (mean +/- sd) were 46.1% +/- 9.8%, 43.2% +/- 9.8%, 45.9% +/- 10.2%, 33.2% +/- 9.2%, 24.9% +/- 4.1%, and 31.8% +/- 8.4% in Groups I, II, III, IV, V, and VI, respectively. GIT% was significantly less in Group V than in Groups I, II, III, and IV (P < 0.05). The Group VI mean value was significantly lower than those of Groups I, II, and III (P < 0.05) but not different from those of Groups IV and V (P > 0.05). The antitransit effect of fentanyl was shown to have increased in the experimental sepsis model, but no decrease in GIT was obtained with tramadol. This was thought to be the result of an associated endogenic opioid system activation and receptor upregulation in sepsis.

Assessment of in-hospital cardiopulmonary resuscitation using Utstein template in a university hospital.

The aim of this study was to evaluate the effectiveness of in-hospital cardiopulmonary resuscitation (CPR) strategies and identify key predictors of post-CPR survival in a university hospital setting. Using a form recommended by the European Resuscitation Council, data regarding in-hospital CPR attempts from January 2001 to December 2002 were recorded and analyzed. The main outcomes of interest were immediate survival after CPR and survival to hospital discharge. Of 307 patients who suffered cardiac arrest in the study period, 103 (33.5%) were resuscitated. Of these 103 patients, 28 (27.2%) survived immediately and 12 (11.7%) survived to hospital discharge. The key predictors of immediate survival were CPR duration and initial cardiac rhythm as monitored by ventricular fibrillation/pulseless ventricular tachycardia (VF/VT). The key predictors of survival to hospital discharge were CPR duration, immediate defibrillation, Glasgow Coma Scale score, and Early Prediction Score. Together, our results suggest that in-hospital CPR strategies require improvement. They also underscore the importance of data collection and analysis in evaluating the effectiveness of inhospital CPR strategies.

Is skin disinfection with 10% povidone iodine sufficient to prevent epidural needle and catheter contamination?

BACKGROUND AND OBJECTIVES: Epidural space infection is a potential complication of epidural catheter placement. In this study, we investigated the incidence of epidural needle and catheter contamination after skin surface disinfection with 10% povidone-iodine (PI). METHODS: Sixty seven patients having surgery under epidural anesthesia were enrolled in this prospective study. After preparation with 10% PI, skin swab cultures were taken from the site of catheter insertion. Epidural needles were cultured immediately after epidural catheters were placed. Catheters were removed at 48 hours and 2 to 3 cm of the distal tips were cultured as well. RESULTS: Fifty-six skin swabs, 52 epidural needles, and 48 catheters were cultured. Although only 3.5% (2) colonization was observed on skin surface cultures, 34.6% (18) of the epidural needles and 45.8% (22) of the catheters were colonized. No systemic or local infection was observed. CONCLUSIONS: Our results suggest that despite skin surface disinfection with PI, there is still significant risk for contamination of needles and catheters during epidural catheterization.
