Chronic obstructive pulmonary disease (COPD) significantly reduces quality of life and is one of the main causes of chronic morbidity and mortality worldwide. Acute exacerbation of COPD (AECOPD) is a life-threatening condition that causes rapid deterioration of respiratory symptoms (worsening of dyspnea, cough and/or abundant sputum production) requiring urgent treatment. This review article examines the evidence underlying supplemental oxygen therapy and ventilator support during exacerbations of COPD. In the introduction, we discuss the epidemiology and pathophysiology of hypercapnic respiratory failure, and then we explain that the key to achieving appropriate levels of oxygenation is using controlled low-flow oxygen therapy. In patients with risk of hypercapnia a target oxygen saturation (SaO ) range of 88%–92% 2 is now generally accepted unless hypercapnia is disproved by gas analysis of arterial blood. However, if the partial pressure of carbon dioxide in arterial blood (PaCO ) is normal, oxygen therapy may target the usual saturation range of 94%–98%. 2 Many COPD patients may have a lower stable SaO , such that chasing this target (94%-98%) is not usually necessary unless 2 the patient is unwell. Further, we review current recommendations for ventilatory support in patients with AEHOBP. Noninvasive ventilation has assumed an important role in managing patients with acute respiratory failure. The use of invasive ventilation is the last remaining option, associated with a poor outcome.

The aim of this study was to perform a comparative analysis applied conventional (traditional) and protective mechanical lung ventilation in clinical conditions with regard to intraoperative parameters changes of oxygenation, ventilation and acid-base status. This was a prospective study that included 240 patients. All patients underwent the same elective surgery (classic cholecystectomy). Patients were divided into two groups of 120 patients, A and B. In group A during the operation had received conventional lung ventilation with tidal volume of 10-15 ml/kg body weight, respiratory rate 12/min. and a PEEP zero. In group B was applied protective lung ventilation with a tidal volume of 6-8 ml/kg body weight, respiratory rate 12/min. and a PEEP of 7 mbar. Monitoring of oxygenation included the monitoring SaO2 and PaO2. Monitoring of ventilation included the determination of the value of tidal volume and minute volume ventilation, peak inspiratory pressure (Ppeak), medium pressure in the airway (Paw.mean), PEEP, PaCO2 and EtCO2. Monitoring of acid-base status was performed via determination of the pH values of arterial blood. Monitoring was carried out in four intervals: T1 - 5-10 minutes after the establishment of the airway, T2 - after opening peritoneum, T3 - after removal of the gallbladder, T4 - after the closure of the abdominal wall. All monitoring results are presented as mean. The statistical significance of differences in mean values was tested by t - test mean values in the case of two independent samples. As a statistical significance test taken as standard values p <0.01 and p <0.001. Comparative analysis of the value of SaO2, PaO2, Ppeak did not reach statistical significance. Statistical significance there is in the analysis of values of tidal volume and Paw.mean (p <0.001). Analysis of PaCO2 and pH of arterial blood showed no statistical significance in the first interval measurements but did interval T2-T4 (p <0.001). Based on the results of this study, it can be concluded that the applied types of mechanical ventilation of lungs during the performance of surgical procedures of medium duration, have not led to significant changes in terms of maintaining the parameters of oxygenation, ventilation and acid-base status, and they stayed in normal, physiological range.

Cilj ove studije je bio da definišemo faktore koji bi mogli da poboljšaju ishod reanimacije pacijenata koji su doživeli vanbolnički akutni zastoj srca poštujući "Utstein" model sakupljanja podataka. U dvogodišnjoj prospektivnoj studiji ispitano je 200 pacijenata koji su doživeli vanbolnički akutni zastoj srca i faktori koji su povezani sa preživljavanjem. 78% pacijenata je doživelo akutni zastoj srca kardijalne etiologije, 65% u kućnim uslovima, 3,7% je reanimirano od strane spasilaca, 36% je zatečeno u ventrikularnoj fibrilaciji (VF) ili ventrikularnoj tahikardiji (VT) bez pulsa, 64% u asistoliji/električnoj aktivnosti bez pulsa (PEA), 52% pacijenata je intubirano na mestu nastanka akutnog zastoja srca i preživljavanje do otpusta iz bolnice je bilo značajno veće u ovoj grupi pacijenata. Prosečno vreme stizanja do pacijenata bilo je 6,6 minuta. 66,7% pacijenata je defibrilirano nakon 4 i više minuta. 131 (65,5%) pacijent je proglašen mrtvim na terenu, 69 pacijenata je transportovano u bolnicu. 53 (76,8%) pacijenta iz grupe transportovanih je umrlo za vreme transporta ili na odeljenju reanimacije, 7 je umrlo nakon prijema u bolncu a 9 je preživelo do otpusta iz bolnice. Multivarijantnom logističkom regresijom je utvrđeno da su varijable značajno povezane sa preživljavanjem: starosno doba, endotrahealna intbacija na terenu i vreme stizanja do pacijenta. Uspeh reanimacije bio je značajno veći kod mlađih pacijenata, kod onih intubiranih na terenu i kod onih kod kojih je ekipa hitne medicinske pomoći stigla u kraćem vremenskom intervalu.

Introduction: antibiotic prophylaxis in surgical patients is defined as the use of antibiotics to prevented infection of the operating field. Applies in cases where the infection is not clinically manifested. The aim of this paper is to demonstrate the importance of the prophylactic use of antibiotics in the prevention of postoperative infection for patient's inguinal hernia. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica, which is part of the "preventive use of antibiotics in surgical patients, through follow-up prospective study of 200 patients. The first group (study group-Group I) consisted of 100 patients with inguinal hernia, in which we apply the prophylactic use of antibiotics. Study group was divided into two subgroups: (Group IA), 50 patients with inguinal hernia in which the solution methods with installation of mesh. (Group IB), 50 patients with inguinal hernia where the tension applied in the treatment methods of treatment. In the second group of patients (control group-Group II) with the same number of patients in the postoperative tre- atment are therapeutic dose used antibiotics. Research results: In our study, the prophylactic purposes, we used compound II generation cephalosporine cefuroxime (Nilacef), which are given in intravenous bolus, the induction of anesthesia, in a dose of 1.5 grams. In 100 patients examined groups, we used prophylactic cefuroxime 100 ampoules (Nilacefa) of 1.5 grams, whi- le the treatment of 100 patients in the control group used for therapeutic purpose 894 ampoules of different antibiotics. Pos- toperative wound infection in patients with prophylactic application of antibiotics are not recorded, while we were in the gro- up where the applied dose of antibiotics therapeutics wound infection noted in two (2%) patients. The average number of days of treatment the study group, the postoperative period was 2.81 days, while patients with a therapeutic dose of antibiotics the average number of days was 5.28. Cost of treatment cefuroksim 50 patients, the prophylactic use amounted to 32,460RSD, while the cost of antibiotics applied in the postoperative treatment of the control group, in which we applied the therapeutic dose antibiotic treatment, was 253,961.52 RSD, which is 7.8 times more expensive. Conclusion: The prophylac- tic application of antibiotics reduced the non-critical use of antibiotics, the incidence of infection of the operating field, mor- bidity and mortality due to postoperative infection, the frequency of resistance to antibiotics, antibiotics to minimize the ef- fect of Bacterian normal flora of the patient, changes in the defense system of the patient, and thus the cost of hospital treat- ment of surgical patients.

Among all ALS procedures, effective airway management is vital in the treatment of critically ill patients. The aim of this study was to evaluate the impact of pre-hospital endotracheal intubation and early defibrillation on outcome of cardiac arrest (CA) patients. We examined 200 patients suffering from out-of-hospital cardiac arrest (OHCA) in a prospective cohort study in a two years period. We determined survival from CA to discharge from hospital and the factors associated with survival. We calculated the time intervals until shock decisions were made. Shock decisions were verified according to EKG downloads. 52% of patients were intubated in the field, survival to discharge from hospital was significantly higher among patients who were intubated in the field. Survival rates in patients with VF/VT was 9.7% compared to patients with asystole/PEA (1.6%). 66.7% of patients were given the shock after 4 minutes. Low survival to hospital discharge may be due to low number of CA patients who were intubated in the field and long "interval to shock delivery" (there are no AED). Existing literature shows that the first minutes are a critical time frame for successful resuscitation and this is an argument towards the introduction of AEDs used by bystanders.

Background: In hernia inguinal regions that are usually on the front wall of the belly may appear epigastric, umbilical and postoperative (incision-ventrale) hernia. Incision (postoperative-ventral) hernia is the kind of hernia that occurs in the area before surgical incision made through the entire thickness of the abdominal wall. Purpose: The aim of this paper is to indicate the frequency incision, epigastric and umbilical hernia, and the validity of some methods used in surgical treatment. Materials and methods: The making of the material used Surgical Clinic KBC Pristina in Gracanica. This prospective study we included 107 (3.43%) patients with hernia abdominal front wall, which were operated in the Surgical Clinic from 2003- 2009th year. Results and discussion: the anterior abdominal wall hernia, are recorded in 48 (44.86%) male patients and in 59 (55.14%) female patients. Age is of great influence on the frequency of anterior abdominal wall hernia, because we have the largest number of hernia 45 (43.14%) recorded in patients older than 61 years. Free hernia we found in 68 (63.55%) and hernia incarcerate of 39 (36.45%) patients. Incision (postoperative) we found a hernia in 44 (41.12%), umbilical in 36 (33.65%) and epigastric of 27 (25.23%) patients. Postoperative hernia is most often occurring after longitudinal laparotomia. We have them registered in 19 (43.18%) patients with infraumbilical, in 10 (22.72%) with supraumbilical, in five (11.36%) with subcostal, with four (9.09%) with transrectal, at two (4.55%) with pararectal laparotomia, in two (4,55%) patients after lumbotomia made with two (4,55%) after Phanensthil incision. The treatment of the anterior abdominal wall hernia in 72 (67.21%) patients, we used prolen net, while in 35 (32.79%) patients made plastic abdominal wall. Drainage was used in 62 (57.94%) operated patients. In 78 (72.90%) patients applied the prophylactic dose of antibiotics, while in 29 (27.10%) patients applied therapeutic dose. The length of treatment of patients who applied prophylactic dose of antibiotics was 2.48 days and length of treatment of patients with therapeutic dose applied was 4.82 days. Prospective studies of patients in the postoperative complications are recorded in four (3.74%) patients. We had wound infection in two (1.87%) and recidive hernia in two (1.87%) patients. Conclusion: This surgical method, when it comes to herniotomia, a direct comparison with the number of postoperative recurrence. Implantation of mesh has found its place and it is a revelation in the resolution of abdominal wall hernia.

Although there is generally world trend in decreasing of number of smokers, expecially in developed part of world, smoking cigarettes still have large importance in morbidity and mortality of modern human population. Taking anamnestics data about smoking habit instruct anaesthesiologist to apply special strategy in general anaesthesia for a reason of possible complications provoked bby a chronic influence of nicotin and other tobbaco ingredients on different organs. In this article we wanted to examine influence of chronic tobbaco smoke exposing on arterial oxygen saturation SaO2 during and short period after general anaesthesia. Research was evaluated on patients in Emergency Center of Clinical Center of Serbia. Patients were divided in two groups (ASAI and II): group I smokers (n=40) and group II nosmokers (n=40). Our investigation has shown no statistical significant difference on SaO2 during general anaesthesia between two experimental groups. Immediately after general anaesthesia and extubation in postoperative period SaO2 dicreases (p<0.001) during transport from operating room to recovery room in both groups of patients,but the level of hypoxemia was significantly higher in smokers group. In this study we demonstrated that tobbaco smoking corellate with postoperative decrease of SaO2 after general anaesthesia, proposing an additional oxygen therapy in early postoperative period.

Echinococcus is a zoonosis, parasitic disease, caused by echinococcus granulosus, E. multilocolaris, E. Vogeli and E. oligarthus. The most frequent at humans is a cystic form of the disease caused by E. granulosus, and rarely the alveolar one caused by E. multilocolaris seu alveolaris. It can affect all the organs and tissues. The most affected ones are: liver (70- 80%) and lungs (10-25%), while rarely, at 5% it can be found in spleen, kidneys, brain, heart, pancreas, mussels and skeleton. The only secure treatment of the primary echinococcosis is the surgical one. It should start immediately after the diagnosis is set in order to avoid complications which follow echinococcosis. Several surgical methods are used in practice for live echinococcus treatment: partial pericystectomia, total cystopericystectomia and liver resection. Aim of the work is to show the importance of the echinococcus cyst of liver and treatment methods. The patient presented in the work is Dj.G., female, register number of the disease history 355/14.05.2007., 61 years old, hospitalized at Surgical Clinic because of the surgery of echinococcus cyst on the left liver lobe. Diagnosis was set by abdomen USG, CT of the abdomen, and laboratory analyses. During the surgery, we found a big echinococcus cyst localized in the second and third segment of liver, so we did a liver resection as a bisegmetectomia with total ekstirpacija of the cyst. Postoperative flow passed normally and the patient
was on the eight postoperative day sent to further home care in a generally and locally good state.

The Early Warning Score is a simple physiological scoring system that can be calculated at the patient's bedside, using parameters which are mesured in the majority of unwell patients. Patients suffering in-hospital cardiac arrest often have abnormal clinical observations documented prior to the arrest. Study objestives:This study assesses wheather these patients have less favourable outcome following in-hospital cardiac arrest. Matherials and the methods:For the present study, the patients' hospital charts were reviewed to identify possible abnormal observations within 8 h prior to the arrest. Results: From the total of 100 patients who sufferd in-hospital cardiac arrest, 64 patients had documentation of vital signs and 9 patients had no documentation of vital signs. Of the patients with documented vital signs 27 (29,7%) had normal vital signs and 64 (70,3%) had abnormal observations. Among these 64 patients the distribution was as follows: 17 patients (13,1%) had respiatory rate below 8 or over 20 per min, 40 (30,8%) had puls rate below 40 or over 140 beats per min, 20 patients (15,4%) had systolic arterial blood pressure below 90 or over 200 mmHg, 5 (3,7%) had temperature (˚C) below 36,1 or over 37,9 ˚C, 20 (15,4%) had oxygen saturation below 90%, 14 (10,8%) had decrease in consciousness and 14 (10,8%) had urine output below 50 ml/2hours). Compared with patients whose EWS were 0-2 (ОR 1,2; 95% CI: 0,935-1,507) patients with EWS 3 or more were 6,5 times more likely to die in first 24 hours (OR: 7,8; 95% CI: 1,205-50,205). Conclusions:Patients with documented clinically abnormal observations prior to in-hospital cardiac arrest have a worse outcome than those without. The main implication of these is that these patients need to be identified in time thereby possibly avoiding arrest. This can also be used when assessing the prognosis of in-hospital patients after achieved ROSC.
