Background: Ultrasound (US)‐guided supraclavicular or infraclavicular blocks are commonly used for upper extremity surgery. The aims of this randomized study were to compare the block performance and onset times, effectiveness, incidence adverse events patient's acceptance US‐guided blocks. We hypothesized that approach, being more superficial easier visualize using a 10 MHz transducer, will produce faster extensive sensory block. Methods: One hundred twenty patients two equal groups: (S)...

Background : The single‐injection axillary block is rapidly performed but gives unpredictable results. Axillary by multiple nerve stimulation technique (MNS) better results, takes longer to perform. Transarterial (TA) injections of high doses local anaesthetics are very successful. This double‐blind study compared both effectiveness and anaesthesiologic time consumption in 100 patients, having an either TA or MNS techniques. Methods 45 mL 1% mepivacaine with adrenaline 5 μg/mL was used each...

Background: This randomized study was designed to compare discomfort caused by axillary or infraclavicular blocks in ambulatory patients. We identified which of the three block components, needle passes, local anesthetic (LA) injections, and electrical stimulations, is most painful quantified pain intensity on a visual analog scale (VAS 0–100). also assessed onset quality analgesia, adverse events patients' acceptance. Methods: Eighty patients were studied. In group – A, four LA injections...

Ultrasound allows visualization of in plane needle insertion toward a nerve and the perineural spread local anesthetic (LA) solution. However, advancement final positioning catheters is difficult to visualize. We assessed feasibility long axis scans for controlling catheter placement.Four orthopedic patients scheduled continuous peripheral blocks (interscalene, femoral, midfemoral sciatic, popliteal sciatic), had inserted under ultrasound guidance. After obtaining adequate short images...

Ultrasound (US)-guided infraclavicular (IC) and axillary (AX) blocks have similar effectiveness. Therefore, limiting procedural pain may help to choose a standard approach. The primary aims of this randomized study were assess patient's during the block recognize its cause.Eighty patients randomly allocated IC or AX group. A blinded investigator asked quantify on Visual Analogue Scale (VAS 0-100) indicate most unpleasant component (needle passes, paraesthesie local anaesthetics injection)....

We have prospectively assessed pain and anxiety of spinal puncture in 180 adult patients randomly allocated to one three equal groups. On the morning surgery group 1 had an EMLA patch, whereas 2 3 placebo patches. Group also infiltration analgesia with ml lignocaine 2% adrenaline, immediately before block. Spinal anaesthesia was performed 25 gauge sharp needles without introducer or 25,27 blunt 20,22 introducers. Patients on a 10‐cm visual analogue scale after removal needle. Pain scores...

Lateral sagittal infraclavicular block by single injection has a faster performance time and causes less discomfort than does axillary multiple injections. This prospective, descriptive, multicenter study assessed effectiveness, onset time, incidence of adverse events verified the noninvasive measurements from magnetic resonance imaging (MRI).One hundred sixty patients were anesthetized use lateral following MRI recommendations for needle insertion. Each patient received mixture that...

In most studies of cardiac output changes after spinal anaesthesia, the time-resolution is limited. The aim this study was to demonstrate with high during onset anaesthesia in elderly patients.We investigated 32 patients aged 60 yr scheduled for elective lower limb surgery. Fourteen received concurrent cardiovascular medication. Cardiac measured every 10 s using a pulse wave algorithm derived from radial artery pressure curve, calibration lithium chloride (LiDCOplus). Data collection ended...

Decreased antibiotic susceptibility among microorganisms isolated from intensive care unit (ICU) patients is found to be associated with high total consumption or inappropriate use of antibiotics in the ICUs. The aims this study were: 1) characterize Danish ICUs, and four ICUs expectedly large differences levels consumption, 2) estimate association between consumption. This was done by: a retrospective questionnaire annual supply 1995 30 Denmark, 2‐month prospective microbiological samples...

Background : Wake‐up tests may be necessary during scoliosis surgery to ensure that spinal function remains intact. Methods Intra‐ and postoperative wake‐up were performed together with somatosensory cortical evoked potentials (SCEPs) monitoring in 40 patients randomized either midazolam (M) or propofol (P) infusions for surgery. Other anaesthetic medication was similar both groups. At the surgeon's request, N 2 O turned off discontinued. In M group, flumazenil given refracted doses....

Background: Intra‐arterial regional anaesthesia (IARA) may be useful for ambulatory hand surgery in patients with poor veins. This randomized, double‐blind study assessed which of the three doses lignocaine gives optimal analgesia a minimum adverse effects. Methods: A preservative‐free, alkalinized 0.5% 1, 2 or 2.89 mg/kg body weight was injected into radial arteries 60 adult patients, allocated to equal groups, produce carpal tunnel releases, capsulotomies, tenosynovectomies, palmar...
