An exclusively unilateral block only affects the sensory, motor and sympathetic functions on one side of the body and offers the advantages of a spinal block without the typical adverse side effects seen with a bilateral block. The lack of hypotension, in particular, makes unilateral spinal anesthesia suitable for patients with cardiovascular risk factors e. g. aortic valve stenosis or coronary artery disease. Increasing numbers of surgical procedures are now being performed on an outpatient basis. Until now, spinal anesthesia has been considered unsuitable for this, not only because of the high incidence of intraoperative hypotension and postoperative urinary retention but also because of the prolonged postoperative stay before home discharge. This is not the case with unilateral spinal anesthesia: motor function returns rapidly, the incidence of urinary retention is extremely low, and patients are usually eligible for home discharge sooner than after bilateral spinal anesthesia or general anesthesia. The success of the technique depends on a number of factors. In addition to the local anesthetic, its concentration and dose, and the baricity of the injected solution, the shape of the spinal needle, the injection speed, the patient's position during injection, and the time the patient remains in this position after injection are equally important parameters. A number of intrathecally applied adjuvant drugs are used to give a more intense and/or longer-lasting block. For this review, we collated the published data on unilateral spinal anesthesia from journals with an impact factor greater than 1.0 and defined an optimized method for performing the technique. In order to achieve an exclusively unilateral block one should use 0.5 % hyperbaric bupivacaine injected at a rate of 0.33 ml/min or slower. During the injection and the following 20 min the patient should lie in the lateral decubitus position on the side intended for surgery with knees drawn to the chest. An injection of 5 mg (1 ml) hyperbaric bupivacaine 0.5 % provides an hour-long block to T 12, and a dose of 7.5 to 10 mg (1.5-2.0 ml) extends the block to T 6. Adding clonidine (0.5 to 1.0 A mu g/kg BW) to the injection prolongs the duration of the block to approximately two to three hours. During the 20-minute fixation period, the cephalad spread of the block can be influenced to a certain extent by raising or lowering the head of the table."],["dc.identifier.doi","10.1007/s00101-016-0232-x"],["dc.identifier.isi","000387657300006"],["dc.identifier.pmid","27778056"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/39072"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","1432-055X"],["dc.relation.issn","0003-2417"],["dc.title","Unilateral spinal anesthesia.

Infrequent use is due to the fact that obtaining selective unilateral block can be difficult, requiring attention to technique. We present a method with a high success rate that uses real-time monitoring of the sympathetic activity of the legs. In this prospective study, 56 patients scheduled for ambulatory knee arthroscopy had spinal anaesthesia in the lateral recumbent position, with hyperbaric bupivacaine 0.5% injected at 0.33 ml/min up to a maximum dose of 5 mg. Sympathetic tone of the legs was monitored by plantar electrical dermal resistance. The clinical effect was assessed by loss of sensation and muscle strength. The haemodynamic course and adverse events were monitored. The motor block was strictly unilateral in 55 patients (98%) and the sensory block was strictly unilateral in 53 patients (94%). The median decrease in systolic blood pressure was 6 mmHg. The time from subarachnoid puncture to arrival in the recovery room was 73 +/- 23 minutes; the duration of stay in the recovery room was 70 +/- 30 minutes. Three patients with a well-established block of adequate extent required conversion to general anaesthesia because of tourniquet pain. Urinary retention only occurred in the sole patient with bilateral block. This method of performing selective unilateral spinal anaesthesia using real-time monitoring of sympathetic tone of the legs has a high success rate and is associated with rapid eligibility for home discharge."],["dc.identifier.isi","000354420400011"],["dc.identifier.pmid","25943609"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37239"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Australian Soc Anaesthetists"],["dc.relation.issn","1448-0271"],["dc.relation.issn","0310-057X"],["dc.title","Selective unilateral spinal anaesthesia for outpatient knee arthroscopy using real-time monitoring of lower limb sympathetic tone"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
