{"title":"[Postoperative apnea--a special risk for former preterm infants].","authors":"M Abel","doi":"","DOIUrl":"","url":null,"abstract":"Infants who had been originally preterm are subject to a particularly high risk after surgical interventions involving anaesthesia, due to a tendency to experience disturbance of respiratory regulation. Of a total of 130 originally preterm infants who had to undergo anaesthesia for so-called minor surgery, respiratory anomalies were seen in 66%, 48%, 10% and 7% of the infants in the age groups of 40, 50, 60 and 80 weeks after conception, respectively. Therapeutic measures were necessary only in patients up to a post-conceptional age of 40 to 50 weeks, the respective incidences being 24% and 20%. To minimise the risk of postoperative early and late apnea in ex-preterm infants, the following measures are presented and discussed: elective surgical interventions should be postponed until after the 50th post-conceptional week; in individual cases, indication for perioperative theophylline/caffeine treatment can be made more precise by means of preoperative ECG-coupled impedance pneumography; all measures of preoperative preparation, choice of anaesthetics and of adjuvant drugs, as well as perioperative infusion therapy, must be taken in full consideration of all neonatal previous diseases; patients up to the 50th week after conception require intensive-care monitoring primary and post-anaesthesiologically for at least 24 hours. In all patients who were older than 50 week after conception, two hours of intensive-care monitoring in the so-called \"recovery from anaesthesia room\" followed by 12 hours of ECG and apnea monitoring proved sufficient; in ex-preterm infants, even minor surgery should be performed on an in-patient basis only, to ensure proper monitoring.","PeriodicalId":7813,"journal":{"name":"Anasthesie, Intensivtherapie, Notfallmedizin","volume":"25 6","pages":"396-8"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13433308","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A literature review].","authors":"A Kaltofen, K H Lindner, H Ensinger, F W Ahnefeld","doi":"","DOIUrl":"","url":null,"abstract":"After intravenous administration of epinephrine, serum potassium level shows a typically biphasic course. The initial rise is followed by a persistent fall to a lower level than the starting-concentration. The initially observed hyperkalemia is supposed to be caused by a potassium release from hepatocytes, mediated by an alpha 1-adrenoreceptor stimulation. The subsequent hypokalemia seems to be caused by the beta 2-mimetic component of epinephrine effecting the uptake of this ion into striated muscle cells. There are numerous clinical reports of marked hypokalemia as a consequence of beta 2-mimetic therapy. The additive effect of elevated endogenous catecholamines with the therapeutically applied epinephrine during cardiopulmonary resuscitation may be the cause of the elevated potassium levels often observed under these conditions. On the other hand, low serum potassium levels were measured in patients after successful resuscitation, as well as in patients with multiple trauma and with severe head injury. Moreover, hypokalemia seems to be a frequent event in the acute phase of myocardial infarction. A catecholamine-induced potassium shift into the cell is considered to be the cause of this decrease. The question whether in the case of myocardial infarction the hypokalemia is in itself arrhythmogenic as yet is not resolved. Because of the present knowledge about the influence of catecholamines on potassium metabolism it seems advisable to monitor potassium levels regularly during the above situations.","PeriodicalId":7813,"journal":{"name":"Anasthesie, Intensivtherapie, Notfallmedizin","volume":"25 6","pages":"405-10"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13433311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A significant decrease of HEP content was found in all groups. In group I and II a significant decrease of HEP was found after one hour of cold storage. After 4 and 8 hours cold storage ATP content was significantly higher in group II. Cardioplegic arrest of dog hearts resulted in a significantly delay of HEP depletion. In group III a significant decrease of ATP was only seen after 12 hours and in group IV already after 6 hours of cold storage. Hearts preserved with the newly developed UW solution showed significantly lower ATP values after 10, 12 and 24 hours than NIH preserved hearts.

No correlation could be found between EVLW and the values of alveolar arterial oxygen difference (AaDO2) and intrapulmonary right-left shunt (Qs/Qt) or haemodynamic values such as CVP, PCWP, mean pulmonary arterial pressure, or the 24 h fluid balance. It was, therefore, not possible to estimate a prognostic trend based on a single measurement of EVLW. However, the course EVLW was more appropriate to perceive the prognostic trend of ARDS because a rapid decrease of very high EVLW was correlated with a decrease of AaDO2 (r = 0.87); whereas lethal ARDS (fibrosis) was associated with moderately increased, unchanged EVLW. However, during the ECCO2-R treatment the repeated estimation of EVLW and AaDO2 is a useful tool to assess recovery because other parameters such as Qs/Qt and chest computer tomography during long-term bypass are very difficult or impossible to employ for this purpose. A change of EVLW with increasing PEEP level could not be found. The reproducibility of 858 EVLW values was excellent with a coefficient of variation of 4.9 +/- 3.5%.","PeriodicalId":7813,"journal":{"name":"Anasthesie, Intensivtherapie, Notfallmedizin","volume":"25 6","pages":"411-5"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13280607","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These patients were compared to 48 patients in the previous 12-month period who had only interventional antibiotic therapy in case of established infections. This selective decontamination of the digestive tract (SDD) reduced the colonisation of the respiratory tract, thus also decreasing incidence of nosocomial pneumonia. There were fewer urinary tract infections, while the incidence of wound infections and septicaemia was influenced to microorganism a lesser degree. The number of gram-negative isolated microorganism was reduced, leading to a shift towards gram-positive organisms, especially S. epidermidis. During the 12-month study period there was no change of antibiotic sensitivity of the isolated microorganisms. Although we encountered no problems associated with multiresistant pathogens, routine microbiological surveillance is strongly recommended to detect changes in antibiotic resistance at an early stage.","PeriodicalId":7813,"journal":{"name":"Anasthesie, Intensivtherapie, Notfallmedizin","volume":"25 6","pages":"416-23"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13330604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following informed consent in 30 patients scheduled for minor gynaecological procedures, anaesthesia was induced with midazolam (0.2-0.3 mg/kg b.w. i.v., group I n = 10), diazepam (0.3-0,4 mg/kg b.w., i.v., group II n = 10) or flunitrazepam (0.03-0.04 mg/kg b.w., i.v., group III n = 10). Auditory evoked potentials were recorded before, during and after induction of general anaesthesia on vertex (positive) and mastoides on both sides (negative). Auditory clicks were presented binaurally at 70 dBnHL with a frequency of 9.3 Hz. Using the electrodiagnostic system Pathfinder I (Nicolet), 1000 successive stimuli were averaged over a 100 ms poststimulus period and analysed off-line. Latencies of the peak V, Na, Pa were measured. By means of Fast-Fourier transformation-analysis corresponding power spectra were calculated to analyse energy portions of the AEP frequency components. In the awake state AEP showed an oscillatory component between 20 and 100 ms poststimulus latency. Corresponding power spectra indicated a predominant 30-40 Hz frequency. After induction of general anaesthesia using midazolam, diazepam and flunitrazepam, there was no increase in latencies of the peaks V, Na, Pa, but only a small decrease in amplitudes Na/Pa without statistical significance. The auditory evoked mid-latency neuronal oscillation persisted under induction of general anaesthesia with midazolam, diazepam, flunitrazepam.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":7813,"journal":{"name":"Anasthesie, Intensivtherapie, Notfallmedizin","volume":"25 6","pages":"383-90"},"PeriodicalIF":0.0,"publicationDate":"1990-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13432731","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
