Forholdet mellom SikkerhetsrÄdet og Den internasjonale straffedomstolen.
Denne Oppgaven tar for seg problemstillinger som oppstÄr i forholdet mellom FNs sikkerhetsrÄd og den internasjonale straffedomstolen. Jeg har valgt Ä se pÄ de juridiske spÞrsmÄlene rundt den rollen SikkerhetsrÄdet er gitt i The Rome Statute of the International Criminal Court, vedtatt 17. juli 1998.
Vurderingstemaet i oppgaven er Ä se pÄ (i) hvilke samarbeidsmekanismer som foreligger, og (ii) hvordan man sÞker Ä lÞse konflikter som mÄtte oppstÄ i SikkerhetsrÄdets forhold til ICC
Minimum effective volume of ropivacaine 7.5mg/ml for an ultrasound-guided infraclavicular brachial plexus block
Background - Ultrasound guidance has been shown to reduce the minimum effective volume (MEV) of local anaesthetics for several peripheral nerve blocks. Although the lateral sagittal infraclavicular block (LSIB) is a wellâestablished anaesthesia method, MEV for this technique has not been established. Our aim with this study was to determine the MEV using ropivacaine 7.5âmg/ml for the LSIB method.
Methods - Twentyâfive adult American Society of Anesthesiologists physical status IâII patients scheduled for hand surgery received an ultrasoundâguided LSIB with ropivacaine 7.5âmg/ml. A successful block was defined as anaesthesia or analgesia for all five sensory nerves distal to the elbow, 30âmin after local anaesthetic injection. The MEV for a successful block in 50% of the patients was determined by using the staircase upâandâdown method introduced by Dixon and Massey. Logistic regression and probit transformation were applied to estimate the MEV for a successful block in 95% of the patients.
Results - The patients received ropivacaine 7.5âmg/ml volumes in the range of 12.5â30âml. The MEVs in 50% and 95% of the patients were 19âml [95% confidence interval (CI), 14â27] and 31âml (95% CI, 18â45), respectively.
Conclusions - For surgery distal to the elbow, the MEV in 95% of patients for an ultrasoundâguided LSIB with ropivacaine 7.5âmg/ml was estimated to be 31âml (95% CI, 18â45âml). Further studies should determine the factors that influence the volume of local anaesthetic required for a successful infraclavicular block
