Obturator Nerve Block for Transurethral Resection of Bladder Tumors.

Background: Bladder tumors are identified and treated using a surgical procedure called as transurethral resection of bladder tumors (TUR-BT). During TUR-BT resection, stimulation of the obturator nerve may cause violent adductor muscle spasms. The "obturator reflex," as this disorder is known, generally causes the legs to move inadvertently (leg jerking). Since this condition can cause several complications, it is preferable to avoid it. Objective: In this study, we investigated the effectiveness of spinal anesthesia combined with obturator nerve block or general anesthetic without muscle relaxant in preventing adductor muscle spasm during TUR-BT procedures. Methods: Forty consecutive patients were enrolled in a prospective observational evaluation and divided into two groups. Patients in Group I underwent spinal anesthesia along with an obturator nerve block, while those in Group II underwent general anesthesia without a neuromuscular relaxant. The following details were recorded: time for obturator block performance, the severity of the motor blockade, the length of the procedure in both groups because a probable adductor spasm might make it more difficult. The level of the surgeon's pleasure was noted throughout the surgery. Additionally, the patient's satisfaction and any issues that may have arisen were documented (the incidence of vascular puncture, hematoma, nerve damage, and visceral injury was noted). Results: Block performance time in Group I was 4.8±0.5 minutes, whereas it was 5.0±0.3 minutes in Group II. The ease of access for the two groups was the same. Group I demonstrated increased patient and surgeon satisfaction with a general anesthesia without neuromuscular relaxants and an obturatorius nerve block. Mean surgical time did not differ between the groups.There were no complications in either group. Conclusion: During such operations, routine use of ONB in combination with spinal anaesthetic or general anesthetic without a neuromuscular blocker can enhance oncological outcomes for patients, reduce complication rates, and extend the period of time spent living without disease.

Pain and Multimodal Analgesia in Laparoscopic Cholecystectomy.

Background: The administration of high doses of opioids during surgery can lead to higher postoperative pain scores at rest and when coughing. Multimodal analgesia may lower the need for opioids during surgery and the suffering of postoperative pain. Multimodal analgesia can be achieved by providing non-opioid drugs (lidocaine, ketamine, and magnesium sulfate), three different types of drugs. Each of these drugs as different analgesic effects and they belong to three different pharmacological groups. The aim of this study is to develop a better understanding of the effects of each drug (lidocaine, ketamine, and magnesium sulfate) on postoperative analgesia, the needs for rescue analgesics, and analyze the total amount of fentanyl during the intraoperative period in patients undergoing laparoscopic cholecystectomy. Methods: 120 patients were enrolled in this randomized controlled study. They were classified as ASA 1 and 2 and were scheduled for laparoscopic cholecystectomy. They were further divided into 3 groups. Group 1, or the lidocaine group, had received lidocaine at 1 mg/kg and a continuous intravenous infusion with lidocaine at 2 mg/kg/h. Group 2, or the ketamine group, received ketamine at 0.5 mg/kg. Group 3, or the magnesium sulfate group, received a continuous intravenous infusion of magnesium sulfate at 1.5 gr/kg. The intensity of postoperative pain was assessed using a VAS score at rest and when coughing, with evaluation at 1, 4, 8, 12, and 24 hours, postoperatively. Also, the needs for rescue analgesics and the total amount of fentanyl during the intraoperative period in all groups was also followed. Results: The patients from the lidocaine group had the highest scores of pain in the postoperative period at rest and when coughing, and the ketamine group had the lowest pain scores. Rescue analgesia was given the most to lidocaine group, and less so in the magnesium group. The magnesium group received the highest dose of fentanyl during surgery and the lowest dose was received by patients from the lidocaine group. Conclusion: Multimodal analgesia can lower the need for opioids in the intra- and postoperative period after laparoscopic cholecystectomy.

Is Multimodal Anesthesia Effecting Postoperative Nausea and Vomiting in Laparoscopic Cholecystectomy?

Background: Multimodal anesthesia represents a technique that can improve analgesia and lower the occurrence of opioid side effects in the postoperative period, such as postoperative nausea and vomiting (PONV). It can be achieved by providing different types of medication during the intraoperative period which can decrease the need for opioids. PONV happens more often in patients who have received large amounts of opioids during laparoscopic cholecystectomy. In this study, our aim was to observe the occurrence of PONV between three different groups of patients who received lidocaine, ketamine and magnesium sulfate in combination with fentanyl in the intraoperative period. We also observed any additional nausea and vomiting in the three groups as well as the amount of fentanyl given to these groups during operation. Materials and methods: 120 patients aged 20-65 years old were included in this randomized and prospective study, ASA classification 1 and 2, scheduled for laparoscopic cholecystectomy. Patients were classified into three groups randomly: Group 1 (lidocaine group-LG), these patients received lidocaine at 1 mg/kg during induction to general anesthesia and 2 mg/kg/h after intubation in continuous intravenous infusion; Group 2 (ketamine group-KG) these patients received ketamine at 0.5 mg/kg during induction to general anesthesia; and Group 3 (magnesium group-MG) these patients received magnesium sulfate at 1.5 gr/hr as a continuous intravenous infusion after intubation. In all three groups, patients additionally received bolus doses of fentanyl. Postoperative nausea and vomiting were monitored in all three groups at 1, 4, 8, 12, and 24 hours after surgery as a primary objective, and if patients had complainant of vomiting, they were treated with 10 mg of metoclopramid. Between the five control time points, additional nausea and vomiting was recorded as well, as a secondary objective. The third objective was to measure of the total amount of fentanyl given in the intraoperative period. Results: Patients from the lidocaine group experienced less PONV and they received less fentanyl compared to patients of ketamine and magnesium groups. Patients from the ketamine group had more nausea than other groups. In the magnesium group, the rate of vomiting was higher, and they received higher amounts of fentanyl during surgery. Additional nausea and vomiting occurred in 3 patients in the LG, 2 in the KG, and 3 in the MG between the five control time points. The patients from the magnesium group received the highest dose of fentanyl during surgery (307.50 ± 130.4), followed by the patients from the ketamine group (292.50 ± 60.5), and then patients from the lidocaine group (258.75 ± 60.9). The doses of fentanyl that patients received during surgery in all three groups were not statistically significant. Conclusion: Multimodal anesthesia has been shown to lower PONV 24 hours after laparoscopic cholecystectomy and can lower need for opioids during laparoscopic cholecystectomy.

Challenging Treatment of a Female Patient with Extensive Fournier's Gangrene - Case Report.

Fournier's gangrene (FG) is a necrotizing fasciitis of the genital, perianal and perineal regions, caused by multiple anaerobic/aerobic infection. It is a rare but very serious condition with multiple long-term complications and high mortality rate. Early diagnosis and multidisciplinary approach in treatment of complicated cases of FG are crucial to the successful outcome. We report a case of an extensive FG in a 59-years-old female patient with multiple risk factors such as obesity, type 2 diabetes and hypertension. She was hospitalized as an emergency case with diabetic ketoacidosis, sepsis and extensive necrotic lesions located perineal, perianal, genital and spread to inguinal, hypogastric, gluteal and sacrococcygeal region. Fournier's gangrene was diagnosed, and after prompt resuscitation, intravenous fluids, broad-spectrum antibiotics, insulin infusion, emergency aggressive surgical debridement was performed. Several aerobic and anaerobic bacteria were isolated from wound culture and hemoculture. Patient has second debridement after four days. After second debridement was applied metabolic control, broad-spectrum antibiotics coverage, dressing the wound and negative pressure wound therapy (NPWT). Patient was discharged home five weeks after a second debridement in good condition. One month later she underwent reconstructive surgical treatment. Besides extensive FG and multiple comorbidity she was successfully managed with good outcome. Fournier's gangrene remains a life-threatening and fulminant disease which need urgent diagnosis and aggressive medical and surgical treatment, to achieve a reduction in long term complications and mortality rate.

Patient-reported health-related quality of life after colorectal surgery.

<b>Introduction:</b> Colorectal cancer is one of the most common cancers worldwide. In most of these patients, quality of life is deteriorated. </br></br> <b>Aim:</b> The aim of our study was to analyze how the disease affects health-related quality of life (HRQoL) and to examine the role of demographic, disease-related, and other factors in the overall quality of life. The second aim was to identify areas where HRQoL could be improved. </br></br> <b> Material and methods:</b> A cross-sectional questionnaire survey was conducted. The study included a modified version of EQ-5D, as well as clinical and socioeconomic characteristics of the country. Patients over the age of 18, who had colorectar surgery, and were followed up at our clinic, were included in the survey. </br></br> <b>Results:</b> In patients after colorectal surgery, bowel control is a major concern that has an impact on their quality of life. The majority of patients expressed gratitude for the care they received and thanked the health-care providers for it. With the EQ-5D modified questionnaire, the concept of "perfect" health was reviewed and analyzed. A response "no difficulty" in any of the five domains was classified as perfect health. Only one-third of the patients said their health was "ideal" (no problems in any of the EQ-5D five domains). </br></br> <b>Discussion:</b> According to the results of this study, patients with CRC have considerably poorer HRQoL than the general population, as indicated by the EQ-5D utility scores. This discovery is in line with some previous research. </br></br> <b>Conclusion:</b> Colorectal surgery survivors' total HRQoL has been found to be lower than in the general population.

Epinephrine and Dexamethasone as Adjuvants in Upper Extremity Peripheral Nerve Blocks in Pediatric Patients.

Introduction: Regional anesthesia in children in recent years has been accepted worldwide. The increased interest in it is partly due to the use of ultrasonography which provides confidence and accuracy to the anesthesiologic team. Adjuvants are used to extend the duration of the sensory and motor blocking, limiting the cumulative dose of local anesthetics. The use of adjuvants in peripheral nerve blocks in the pediatric population is still under research. Aim: To observe the effect of epinephrine and dexamethasone as adjuvants to local anesthetics in peripheral upper extremity nerve blocks in pediatric patients. Materials and methods: The study included 63 patients, aged group 4-14 years, admitted to the University Clinic of Pediatric Surgery for surgical treatment of upper limb fractures in the period of January 2020 until March 2021. Patients were randomized into three groups, and all patients in the groups received analgo-sedation prior to peripheral nerve block. Patients in group 1 (21 patients) received supraclavicular, or interscalene block with 2 ml lidocaine 2% and bupivacaine 0.25% (max 2mg/kg) with a total volume of 0.5ml/kg. In group 2, the patients (21) received 25 µg of epinephrine in 2 ml of 2% solution of lidocaine and 0.25% bupivacaine (max 2 mg/kg) with a total volume of 0.5 ml/kg, and in group 3, the patients (21) received 2% lidocaine 2ml and 0.25% bupivacaine (max 2mg/kg) in combination with 2mg dexamethasone with a total volume of 0.5ml/kg. Results: Results showed that in patients in group 1, the average duration of the sensory block was 7 hours, while the duration of the motor block was 5 hours and 30 minutes. In group 2 (epinephrine), the durations of both sensory and motor block were prolonged for about 30 minutes on average compared to the first group. In group 3 (dexamethasone) the duration of the sensory and motor block was significantly longer compared with the first two groups (p<0.0001). Conclusion: Epinephrine and dexamethasone prolong the duration of action of local anesthetics in peripheral nerve blocks of the upper extremity in pediatric patients and thus reduce the need for analgesics in the postoperative period.

Survey of Current Difficult Airway Management Practice.

BACKGROUND: Even for the most experienced anesthesiologists "can't ventilate can't intubate" scenario in difficult airway management is challenging, and although rare it is life-threatening. AIM: The aim of this survey was to analyse the current practice of difficult airway management at our University teaching hospital. MATERIAL AND METHODS: A ten-question-survey was conducted in the Tertiary University Teaching Hospital "Mother Theresa", Clinic for Anesthesia, Reanimation and Intensive Care. The survey included demographic data, experience in training anaesthesia, practice in management of anticipated and non-anticipated difficult airway scenario, preferable equipment and knowledge of guidelines and protocols. Responses were noted, evaluated and analysed with the SPSS statistical program. RESULTS: The overall response rate was very good; 94.5% answered the survey. During the assessment of the level of comfort with diverse airway equipment, there was diversity of answers due the experience of anaesthesia training, although the most frequent technique among all responders for anticipated difficult intubation was video laryngoscopy (48%). As for non-anticipated difficult intubation when conventional techniques failed to secure the airway most of the responders answered that they used supra-gothic airway device - laryngeal mask (38%) as a rescue measure. CONCLUSION: Airway assessment, adequate training, experience, and availability of essential equipment are the pillars of successful airway management.

Hypernatremia-induced Neurologic Complications After Hepatic Hydatid Cyst Surgery: Pretreat to Prevent.

INTRODUCTION: Surgery is effective treatment for echinococcosis; however, there is a risk of hypertonic saline resorption and acute hypernatremia. AIM: We report two cases of severe hypernatremia following hydatid cyst removal. CASE REPORTS: A 17-year-old girl underwent surgical removal of hepatic hydatid cyst. Following the surgery, she developed seizures evolving to status epilepticus, and was sedated and mechanically ventilated. Blood chemistry showed hypernatremia. Fluid resuscitation with 5% dextrose infusions was started in combination with furosemide. Electrolytes were monitored frequently until plasma sodium levels normalized, 30 hours later. The patient was seizure free 48 hours later. The second patient is a 70-year-old man with hepatic hydatid cyst. After the surgery he became somnolent and confused due to severe hypernatremia. Intravenous administration of five percentage dextrose was initiated and high doses of furosemide. Sodium level normalized within 38 hours. The patient's mental status improved. CONCLUSION: A hospital protocol was established aiming to prevent hypernatremia and neurological complications.

Side Effects of Intravenous Patient-Controlled Analgesia with Remifentanil Compared with Intermittent Epidural Bolus for Labour Analgesia - A Randomized Controlled Trial.

INTRODUCTION: Epidural analgesia is considered a gold standard in obstetric anaesthesia and analgesia. However, in situation when it is contraindicated, unwanted by the patient or simply unavailable, remifentanil can be an excellent alternative. The goal of our study is to analyse the side effects of intravenous patient-controlled analgesia (IV PCA) with remifentanil compared with epidural analgesia during delivery. MATERIAL AND METHODS: This study included 155 pregnant women in term for birth, divided into 2 groups: a remifentanil group (RG), and an epidural group (EG). Patients in the RG received intravenous PCA with remifentanil, while patients in the ЕG received epidural analgesia with programmed intermittent bolus dosing. Our primary outcome was maternal safety; the secondary outcome was neonatal safety. RESULTS: The results present a significantly lower SaO2 value of the parturients in the RG (96.95 ± 1.4 vs 98.22 ± 0.6), and a significantly higher respiratory rate per minute in the EG at all time points after the onset of analgesia (20.85 ± 1.4 vs 18.67 ± 0.9). There was more frequent sedation, nausea and vomiting in the RG, while in the EG there was a more elevated temperature, itching and irregularities in the CTG record. Regarding the newborn, there was no significant difference between the two groups in the Apgar scores, pH, pCO2, pO2, and bicarbonate, while there was a significantly lower value of the base excess in the RG group. CONCLUSION: PCA with remifentanil is safe for the mother, foetus and the newborn, with minimal side effects. Continuous respiratory monitoring, oxygen supply and following of all consensus recommendations are mandatory.

Pain Relief as an Integral Part of the Palliative Care.

BACKGROUND: Palliative therapy represents active care for patients whose illness has such nature that is not responding to the curative treatment. The palliative care aims to provide comfort and prevention from the suffering of the patients at the end of their life. Treatment of the pain presents an important integral part of palliative care. AIM: This article aims to discuss and answer to some of the analgesic regimes and therapeutic dilemmas. RESULTS: Pain control, in addition to the other treatments such as alleviation of psychological, sociological and spiritual problems, has a priority. The proper pain management can achieve a better quality of life for the patients and their families. CONCLUSION: It can be concluded that because of the different origin of the pain, the use of analgesic therapy should be individualised and adapted to the real need of every person. Finally, only a good organisation and institutionalisation of the palliative care in one society could permit better prevention of suffering at the end of the life.

Opioid Free Anesthesia for Laparotomic Hemicolectomy: A Case Report.

Opioid free anesthesia (OFA) is deffined as anaesthesiological technique where opioids are not used in the intraoperative period (systemic, neuroaxial or intracavitary). Anaphylaxis caused by opioids (fentanyl) is very rare, and the reaction is presented with hypotension and urticaria. When we have proven allergy to fentanyl, patients' refusal of placing epidural catheter and refusal of receiving bilateral ultrasound guided transversus abdominis plane block (USG TAPB), we must think of using multimodal nonopioide analgesia. The concept of multimodal balanced analgesia is consisted of giving different analgesic drugs in purpose to change the pathophysiological process which is included in nociception, in way to receive more effective intraoperative analgesia with less adverse effects. This is a case report of a 60-year-old male patient scheduled for laparotomic hemicolectomy, who previously had proven allergy to fentanyl. We have decided to give him an opioid free anaesthesia. Before the induction to anaesthesia, the patient would receive dexamethasone (dexasone) 0.1 mg/kg and paracetamol 1 gr intravenously. The patient was induced into general endotracheal anesthesia according to a standardized protocol, with midazolam 0.04 mg/kg, lidocaine hydrochloride 1 mg/kg, propofol 2 mg/kg and rocuronium bromide 0.6 mg/kg. Anaesthesia was maintained by using sevoflurane MAC 1 in order to maintain mean arterial pressure (MAP) with a value of +/- 20% of the original value. After tracheal intubation, the patient had received ketamine hydrochloride 0.5 mg/kg (or 50 mg ketamine) in bolus intravenously and a continuous intravenous infusion with lidocaine hydrochloride (lidocaine) 2 mg/kg/hr and magnesium sulfate (MgSO4) 1,5 gr/hr. At the end of surgery the continuous intravenous infusion with lidocaine and magnesium sulfate was stopped while the abdominal wall was closed and 2.5 g of metamizole (novalgetol) was given intravenously. VAS score 2 hours after surgery was 6/10 and 1 gr of paracetamol was given and the patient was transferred to the Department. Over the next 3 days, the patient had a VAS score of 4-6/10 and only received paracetamol 3x1g and novalgetol 3x1 gr daily, every four hours.

The Influence of Smoking on the Variations in Carboxyhemoglobin and Methemoglobin During Urologic Surgery.

INTRODUCTION: Surgery is supposed to modulate the production of carbon monoxide by the reduction of heme oxygenase activity or transcriptional regulation of inducible heme oxygenase. On the other hand, the inhalation of tobacco smoke can substantially raise the level of carboxyhemoglobin in the blood. Furthermore, methemoglobin is maintained at a constant level. However, excessive production of methemoglobin relative to total methemoglobin reductase activity results in methemoglobin increase. AIM: The aim of our study was to investigate the perioperative variations of carboxyhemoglobin and methemoglobin during urologic surgeries, and at the same time to evaluate the changes in methemoglobin as a possible indicator of nitric oxide generation. Our second aim was to evaluate the effect of preoxygenation on the level of carboxyhemoglobin and methemoglobin and the influence of blood transfusion on their changes. MATERIAL AND METHODS: The study included 30 patients scheduled for urologic surgery under general endotracheal anesthesia, aged 18-60 years without any history of respiratory disease, divided into two groups. The study group comprised patients who were smoking cigarettes or tobacco pipe, while the control group included non-smokers. In both groups carboxyhemoglobin (COHb) and methemoglobin (MetHb) levels were determined preoperatively, after preoxygenation, and postoperatively. RESULTS: COHb levels were decreased postoperatively in both groups. The average values of COHb between the two groups were statistically significantly different (p=0.00). MetHb levels increased postoperatively in the group of smokers and decreased in the group of non-smokers. There were no statistically significant differences in the average postoperative MetHb levels between the two groups. CONCLUSION: Changes in carboxyhemoglobin and methemoglobin concentrations in arterial blood occur during urologic surgery, although these amplitudes are small when compared with carbon monoxide intoxication and methemoglobinemia. It is likely that organ perfusion and functions are affected by these monoxide gas mediators during urologic surgery.

Synergistic Effect of Hyperoxia and Biotrauma On Ventilator-Induced Lung Injury.

Patients undergoing mechanical ventilation in intensive care units (ICUs) may develop ventilator-induced lung injury (VILI). Beside the high tidal volume (Vt) and plateau pressure (Pplat), hyperoxia is supposed to precipitate lung injury. Oxygen toxicity is presumed to occur at levels of fraction of inspired oxygen (FiO2) exceeding 0.40. The exposure time to hyperoxia is certainly very important and patients who spend extended time on mechanical ventilation (MV) are probably more exposed to severe hyperoxic acute lung injury (HALI). Together, hyperoxia and biotrauma (release of cytokines) have a synergistic effect and can induce VILI. In the clinical practice, the reduction of FiO2 to safe levels through the appropriate use of the positive end expiratory pressure (PEEP) and the alignment of mean airway pressure is an appropriate goal. The strategy for lung protective ventilation must include setting up FiO2 to a safe level that is accomplished by using PaO2/FiO2 ratio with a lower limit of FiO2 to achieve acceptable levels of PaO2, which will be safe for the patient without local (lungs) or systemic inflammatory response. The protocol from the ARDS-net study is used for ventilator setup and adjustment. Cytokines (IL-1, IL-6, TNFα and MIP-2) that are involved in the inflammatory response are determined in order to help the therapeutic approach in counteracting HALI. Computed tomography findings reflect the pathological phases of the diffuse alveolar damage. At least preferably the lowest level of FiO2 should be used in order to provide full lung protection against the damage induced by MV.

The Effect of Rectus Sheath Block as a Supplement of General Anesthesia on Postoperative Analgesia in Adult Patient Undergoing Umbilical Hernia Repair.

BACKGROUND: Ultrasound guided rectus sheath block can block the ventral rami of the 7th to 12th thoracolumbar nerves by injection of local anesthetic into the space between the rectus muscle and posterior rectus sheath. The aim of this randomized double-blind study was to evaluate the analgesic effect of the bilateral ultrasound guided rectus sheath block as supplement of general anesthesia on patents undergoing elective umbilical hernia repair. METHODS: After the hospital ethics committee approval, 60 (ASA I-II) adult patients scheduled for umbilical hernia repair were included in this study. The group I (n=30) patents received only general anesthesia. In the group II (n = 30) patents after induction of general anesthesia received a bilateral ultrasound guided rectus sheath block with 40 ml of 0.25% bupivacaine. In this study we assessed demographic and clinical characteristics, pain score - VAS at rest at 2, 4, 6, 12 and 24 hours after operation and total analgesic consumption of morphine dose over 24-hours. RESULTS: There were statistically significant differences in VAS scores between the groups I and II at all postoperative time points - 2hr, 4 hr, 6 hr, 12 hr and 24 hr. (P < 0.00001). The cumulative 24 hours morphine consumption after the operation was significantly lower in the group II (mean = 3.73 ± 1. 41) than the group I (mean = 8.76 ± 2.41). This difference was statistically significant (p = 0.00076). CONCLUSION: The ultrasound guided rectus sheath block used for umbilical hernia repair could reduce postoperative pain scores and the amount of morphine consumption in 24 hours postoperative period.

Association of Single-Nucleotide Polymorhism C3435T in the ABCB1 Gene with Opioid Sensitivity in Treatment of Postoperative Pain.

BACKGROUND: The minimal effective analgesic concentration of opioids required for satisfactory analgesia may differ significantly among the patients. Genetic factors may contribute to the variable response to opioids by affecting their pharmacokinetics or pharmacodynamics. METHODS: Ninety nine patients undergoing abdominal surgery with colorectal anastomosis because of colorectal carcinoma were enrolled in the present study. C34535T was genotyped in all subjects and the patients were divided into three groups according to their genotype: CC-wild type homozygous, CT-mutant heterozygous and TT-mutant homozygous. Intravenous fentanyl, patient controlled analgesia was provided postoperatively for pain control in the first 24 hour after surgery. Opioid consumption, pain scores and the adverse side effects were evaluated. RESULTS: Our main result is that the patients in the CC genotype group consumed significantly more fentanyl (375.0 µg ± 43.1) than the patients in the TT group (295.0 µg ± 49.1) and the CT (356.4 µg ± 41.8) group in the treatment of postoperative pain. The patients in the TT group had lower VAS scores at 6h, 12h, 18 h and 24h postoperatively. There were no significant differences in the side effects among the three groups regarding the vomiting and the sedation score. The patients in the TT group had more frequently nausea score 1, than the patients in the other two groups. CONCLUSION: Our study indicates that the C3435T SNPs of the ABCB1 gene is associated with differences in the opioid sensitivity. The ABCB1 polymorphism may serve as an important genetic predictor to guide the acute pain therapy in postoperative patients.

Rhabdomyolysis in Critically Ill Surgical Patients.

INTRODUCTION: Rhabdomyolysis is a syndrome of injury of skeletal muscles associated with myoglobinuria, muscle weakness, electrolyte imbalance and often, acute kidney injury as severe complication. THE AIM: of this study is to detect the incidence of rhabdomyolysis in critically ill patients in the surgical intensive care unit (ICU), and to raise awareness of this medical condition and its treatment among the clinicians. MATERIAL AND METHODS: A retrospective review of all surgical and trauma patients admitted to surgical ICU of the University Surgical Clinic "Mother Teresa" in Skopje, Macedonia, from January 1st till December 31st 2015 was performed. Patients medical records were screened for available serum creatine kinase (CK) with levels > 200 U/l, presence of myoglobin in the serum in levels > 80 ng/ml, or if they had a clinical diagnosis of rhabdomyolysis by an attending doctor. Descriptive statistical methods were used to analyze the collected data. RESULTS: Out of totally 1084 patients hospitalized in the ICU, 93 were diagnosed with rhabdomyolysis during the course of one year. 82(88%) patients were trauma patients, while 11(12%) were surgical non trauma patients. 7(7.5%) patients diagnosed with rhabdomyolysis developed acute kidney injury (AKI) that required dialysis. Average values of serum myoglobin levels were 230 ng/ml, with highest values of > 5000 ng/ml. Patients who developed AKI had serum myoglobin levels above 2000 ng/ml. Average values of serum CK levels were 400 U/l, with highest value of 21600 U/l. Patients who developed AKI had serum CK levels above 3000 U/l. CONCLUSION: Regular monitoring and early detection of elevated serum CK and myoglobin levels in critically ill surgical and trauma patients is recommended in order to recognize and treat rhabdomyolysis in timely manner and thus prevent development of AKI.

New technique of compression anastomosis in colorectal surgery - first results in 25 patients in Macedonia.

AIM: Clinical evaluation of the safety and effectiveness of compression anastomosis with ColonRing™ for large-bowel end-to-end anastomosis for rectal cancer and explanation of the procedure and the device itself since this device is used for the first time in our clinic. MATERIAL AND METHODS: In November, 2012, a team of surgeons from our clinic attended the Clinical practice workshop in Belgrade, Serbia which was organized by the World Congress of Compression Anastomosis (WCCA) and held by its President Prof. Dr. Steven Wexner from Cleveland Clinic in USA. On this workshop, all aspects of technical point of view were obtained and surgeons were certified for the technique. A total of 25 patients have been scheduled for elective colorectal surgery with subsequent compression anastomosis using ColonRing. All patients were operated for high and mid rectal cancers excluding the low rectal cancers, since those patients are usually diverted with decompressive ileostomy. Patients, who are diverted, are at higher risk of retaining the ring, after its dislodgement, in the ampulla of the rectum since they do not have natural excretion of stool via the anus. All patients were followed for anastomotic leak, anastomotic bleeding, stricture formation, device (ColonRing) handling in general and time of expulsion of the ring via anus. RESULTS: We used this technique for the first time in 2013 and since then a total of 25 patients underwent anterior resection of the rectum with subsequent colorectal compression anastomosis using ColonRing. Of all patients, 9 were female while 16 were male with median age of 64 years. All patients were operated for rectal cancers. The mean length of hospital stay was 7.4 days (range 5 to 9 days). None of the patients developed anastomotic bleeding or dehiscence. To date none of the patients developed anastomotic stricture, although some patients were followed for almost two years. The average day of expulsion from the body could not be calculated since despite, and although all patients were given instruction on how to check for ring expulsion, 21 of them did not report this event. Only 2 patients brought the ring to us. In two cases after 2 week of the initial operation, the ring was find and palpated on digital rectal examination, free in the ampulla of the rectum and was easily removed via the anus during the examination. Misfiring was reported in 1 patient (first patient) and reanastomosis was employed using another ColonRing, No perioperative mortality was observed in this patient population. CONCLUSION: End-to end colorectal anastomosis with the ColonRing is feasible and safe procedure with fast learning curve. To date, this type of anastomosis is possible in left sided colon lesions where anastomosis is contemplated below the promontory. We find the device easy to use with high level of confidence. Further prospective studies including comparison between the ColonRing device and the conventional staplers evaluating long-term anastomotic complications (i.e., leak or stricture) are needed to evaluate the benefits and limitations of this device.

Evaluation of Anesthesia Profile in Pediatric Patients after Inguinal Hernia Repair with Caudal Block or Local Wound Infiltration.

AIM: The aim of this study is to evaluate anesthesia and recovery profile in pediatric patients after inguinal hernia repair with caudal block or local wound infiltration. MATERIAL AND METHODS: In this prospective interventional clinical study, the anesthesia and recovery profile was assessed in sixty pediatric patients undergoing inguinal hernia repair. Enrolled children were randomly assigned to either Group Caudal or Group Local infiltration. For caudal blocks, Caudal Group received 1 ml/kg of 0.25% bupivacaine; Local Infiltration Group received 0.2 ml/kg 0.25% bupivacaine. Investigator who was blinded to group allocation provided postoperative care and assessments. Postoperative pain was assessed. Motor functions and sedation were assessed as well. RESULTS: The two groups did not differ in terms of patient characteristic data and surgical profiles and there weren't any hemodynamic changes between groups. Regarding the difference between groups for analgesic requirement there were two major points - on one hand it was statistically significant p < 0.05 whereas on the other hand time to first analgesic administration was not statistically significant p = 0.40. There were significant differences in the incidence of adverse effects in caudal and local group including: vomiting, delirium and urinary retention. CONCLUSIONS: Between children undergoing inguinal hernia repair, local wound infiltration insures safety and satisfactory analgesia for surgery. Compared to caudal block it is not overwhelming. Caudal block provides longer analgesia, however complications are rather common.

Seizure outcome following medical treatment of mesial temporal lobe epilepsy: Clinical phenotypes and prognostic factors.

OBJECTIVE: Surveys on mesial temporal lobe epilepsy (MTLE) repeatedly demonstrate that seizures are commonly resistant to antiepileptic drugs (AED), but patients usually came from third-level epilepsy centers, making the medically refractory population larger. The aim of our study is to evaluate patterns of seizure control and prognostic factors of general population of MTLE patients observed in clinical practice. METHODS: Sixty five MTLE patients were evaluated for demographic data, family history, febrile convulsions, detailed descriptions of auras and seizures, presence of secondarily generalized seizures, age at seizure onset, duration of epilepsy, epileptiform discharges in EEG, neuroradiological findings and AED schedules with therapeutic response. According to seizure frequency, patients were divided into three groups: (1) seizure-free (SF) patients at the time of evaluation, (2) patients considered as having infrequent seizures (IS) if they presented only auras or up to three dyscognitive (complex partial) seizures per year and (3) patients with higher rate were regarded as having frequent seizures i.e. being drug-resistant (DR). For each clinical parameter, the three groups were compared statistically. In addition, following the patterns of evolution over time, patients were categorized into two groups: continuous pattern, with no period of remission, and intermittent pattern, in which patients had at least one period of remission. RESULTS: Ten patients (15.4%) were seizure free, 19 (29.2%) had infrequent seizures, while 36 patients (55.4%) had frequent uncontrolled seizures. Ten (52.6%) IS patients and ten (27.7%) DR patients had a intermittent i.e. relapse-remitting pattern with at least one period of two years without seizures. Female patients dominated SF group and the gender difference with other groups reached statistical significance (p=0.02). Comparing the groups, DR group had longer seizure duration than IS group (12.6±10.9years vs. 22.8±10.6years, p=0.006). Number of tried AEDs (p<0.00006) was significantly lower in the seizure-free patients. Other variables are not related to course of the epilepsy. CONCLUSION: MTLE is a heterogeneous syndrome, 45% of patients in our series were having either rare auras or seizures or were seizure-free. The factors associated with drug resistance were longer duration of epilepsy, higher number of previously tried AED and male gender.
