Dacryocystorhinostomy (DCR) is the procedure designed to treat primary or secondary adult anatomical obstruction. External DCR is the traditional surgical approach, however endoscopic DCR can be done. In the past, general anaesthesia (GA) has been considered as the gold standard for DCR surgery; endotracheal intubation and throat pack offer an important function as protective mechanisms of the patient’s airway against blood aspiration. Head up position, hypotensive anaesthesia, incision infiltration with lidocaine/epinephrine together with insertion of nasal pack soaked in decongestant solution are a routine measures to guard against intraoperative bleeding that may hinder surgical site visualization. Increase awareness of regional anaesthesia efficacy contemplated the surgeons towards the use of such techniques. The basic concept of local anaesthesia for DCR involves blockade of infratrochlear, infraorbital and anterior ethmoidal nerves either by separate injections or by local infiltration along with intranasal preparation. It has been found that DCR under regional anaesthesia minimizes intraoperative bleeding, inpatient stay and reduce health care expenditure. Further, many patients prefer regional anaesthesia due to less postoperative pain. These benefits are desirable particularly in elderly population in whom GA constitute a threat for their life.</p></div>","PeriodicalId":81055,"journal":{"name":"Current anaesthesia and critical care","volume":"21 4","pages":"Pages 180-183"},"PeriodicalIF":0.0,"publicationDate":"2010-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.cacc.2010.02.010","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84348021","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}

Typically, the anaesthetist administers boluses of approximately 200–250 ml of colloid solution whilst measuring changes in stroke volume or another measure of fluid responsiveness, such as stroke volume variation. When the stroke volume measurements indicate that the cardiovascular system is no longer fluid responsive, the patient is assumed to be close to the upper flat phase of the Frank–Starling Curve. Research using TFA suggests that post-operative complications such as ileus and length of hospital stay are reduced when fluid therapy is managed in this way. Most of the positive evidence for TFA has been achieved using the oesophageal Doppler (CardioQ, Deltex Medical, Chichester UK), although other cardiac output monitors are available, there are few clinical outcome studies that justify their use in routine practice. Widespread adoption of TFA for patients undergoing major surgery will help achieve the goals of enhanced recovery.</p></div>","PeriodicalId":81055,"journal":{"name":"Current anaesthesia and critical care","volume":"21 3","pages":"Pages 108-113"},"PeriodicalIF":0.0,"publicationDate":"2010-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.cacc.2010.01.001","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75917743","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}
