Abstract:

Abstract Objective To analyse , all phases of palliative sedation therapy ( PST ) procedure in our Palliative Care Unit , in patients who died during the palliative care process ( PCP ) . Method A retrospective and descriptive study was conducted . The clinical histories of patients admitted to a Chronic and Long Term Care Hospital in Valencia during the period from July 15 , 2009 and June 15 , 2010 were reviewed . The general variables of the patients , as well as those specific to the PST , were analysed . The data analysis was performed using SPSS 15 .0 statistical program . Results PST was performed on 51 patients ( 17 .7% of deaths ) . The majority ( 76 .5% ) were over 64 years old , with an oncological disease ( 63% ) and , on admission , total dependence ( 76 .5% ) , and with a significant degree of cognitive impairment ( 65% ) and malnutrition ( 84 .5% ) . The most common refractory symptoms ( RS ) were : dyspnea ( 38 .5% ) , pain ( 23% ) , non - specific suffering ( 23% ) , and agitation ( 20 .5% ) . The steps of PST that were recorded less frequently were : near death situation ( 37% ) , and intensity ( 41% ) , and the reason for the refractoriness ( 31% ) of the RS . The informed consent ( IC ) was given mostly by the family ( 83% ) , and on the same day the PST was started ( 81% ) . The use of artificial hydration ( AH ) was low ( 12% ) . As a sedative drug was used in 96% of cases , Midazolam ( MDZ ) was the drug most used for sedation ( 96% ) , administered in the vast majority ( 98% ) as a continuous and subcutaneous infusion . The final mean dose of MDZ was 28 mg/day . A major opioid ( 100% ) and an anticholinergic ( 68% ) were associated with PST . Data on the PST monitoring had been recorded in 71% of patients , with acceptable control of the RS in 80% of cases . The average duration of the PST was 68 hours . Non - oncological patients ( NO ) with PST were less likely to be included in the PCP on admission , as well as being more dependent , and less likely to give IC , compared to oncological patients ( O ) . Conclusions The frequency of use and duration of the PST and the RS and their control are within the ranges reported in the literature . It is almost exclusively performed with , and there is little use of AH . There is still significant scope for improvement in certain steps of the PST . To do an Advance Care Planning before the last days of life would increase patient involvement in the IC for PST . The differences in the use of PST in oncological patients and non - oncological patients depends more on distinct clinic and care characteristics than that of the technique itself .
