Seizures may ccur in regular benzdiazepine users Respiratry rate shuld be mnitred cntinuusly until respiratry rate returns t baseline level. Flumazenil has a shrt half-life (much shrter than diazepam) and respiratry functin may recver then deterirate again. Nte: If respiratry rate des nt return t nrmal r patient is nt alert after initial dses give, then assume sedatin is due t sme ther cause. 5 Apprved by Medicines Management Grup Octber 2016

Temperature 2. Pulse 3. Bld pressure 4. Respiratin rate Every 5-10 minutes fr ne hur and then half hurly until patient is ambulatry. If the patient is asleep r uncnscius, the cntinuus use f pulse ximetry t measure xygen saturatin is desirable. A nurse shuld remain with the patient until ambulatry. ECG and haematlgical mnitring are als necessary when parenteral antipsychtics are administered, especially when higher dses are used. Hypkalaemia, stress and agitatin place the patient at risk f cardiac arrhythmias. A crash bag shuld be available within 3 minutes 8.7 Remedial Measures in ADULTS 1 Prblem Acute Dystnia (including culgyric crisis) Reduced respiratry rate (<10 per minute) Or xygen saturatin (<90%) Irregular r slw pulse (<50/min) Fall in Bld pressure (>30 mmhg rthstatic drp r <50 mmhg diastlic) Increased Temperature Remedial Measures Give prcyclidine 5-10mg IM Give xygen raise legs; Ensure that patient is nt lying face dwn. Give flumazenil if benzdiazepine-induced respiratry depressin suspected. If induced by any ther sedative agent and Dr is nt immediately available: TRANSFER TO A MEDICAL BED AND VENTILATE MECHANICALLY Refer t specialist medical care immediately Lie patient flat, tilt bed twards head. Mnitr clsely. Withhld antipsychtics: (risk f NMS and perhaps arrhythmias). Check Creatinine kinase 8.8 Guidelines fr the Use f Clpixl Acuphase (zuclpenthixl acetate) Acuphase shuld nly be used after an acutely psychtic patient has required repeated injectins f shrt-acting antipsychtic drugs such as halperidl r lanzapine r sedative drugs such as lrazepam. Acuphase shuld nly be given when enugh time has elapsed t assess the full respnse t previusly injected drugs therefre allw 15 minutes after IV injectins r 60 minutes after IM administratin. Acuphase shuld never be administered: In an attempt t hasten the antipsychtic effect f any ther antipsychtic therapy Fr rapid tranquillisatin At the same time as ther parenteral antipsychtics r benzdiazepines At the same time as dept medicatin 6 Apprved by Medicines Management Grup Octber 2016

7 8. Rapid Tranquillisatin As a test dse fr zuclpenthixl decanate dept T a patient wh is physically resistive (risk f intravasatin and il emblus). T patients wh accept ral medicatin T patients wh are antipsychtic-naïve T patients wh are less than 12 years ld. T patients wh are sensitive t EPSE T patients wh are uncnscius T patients wh are pregnant T patients with hepatic r renal impairment T patients with cardiac disease Dse Onset and duratin f actin Acuphase shuld be given in a dse f mg, up t a maximum f 400mg ver a tw week perid. This maximum duratin ensures that a treatment plan is put in place. It des nt indicate that there are knwn harmful effects frm mre prlnged administratin, althugh such use shuld be very exceptinal. There is n such thing as a curse f Acuphase. The patient shuld be assessed befre each administratin. Injectins shuld be spaced at least 24 hurs apart. Nte, Zuclpenthixl acetate is widely misused as a srt f chemical straightjacket. In reality, it is a ptentially txic preparatin with very little published infrmatin t supprt its use. It is perhaps best reserved fr thse few patients wh have a prir histry f gd respnse t Acuphase that is, thse patients wh have an advance directive recmmending the use f Acuphase during psychtic episdes. Sedative effects usually begin t be seen 2 hurs after injectin and peak after 12 hurs. The effects may last fr up t 72 hurs. Nte: Acuphase has n place in rapid tranquillisatin: its actin is nt rapid. 8.9 NICE Clinical Guidelines NICE NG10, May 2015, Vilence and Aggressin: Shrt term management in mental health, health and cmmunity settings. NICE defines Rapid Tranquillisatin as the use f medicatin by the parenteral rute (usually intramuscular r exceptinally, intravenus) if ral medicatin is nt pssible r apprpriate and urgent sedatin with medicatin is needed. All staff that prescribe and administer the abve medicatins shuld be: Aware f the risks assciated with pharmaclgical management f acutely disturbed patients, such as: damage t the therapeutic relatinship between service user and Health Care Prfessinal (NICE endrses requesting service users accunts f their experiences upn discharge t anther unit) 7 Apprved by Medicines Management Grup Octber 2016

Aware that there are preferred levels f administratin (the preferred methd f drug administratin being PO, then intramuscular IM and then, and nly if immediate tranquillisatin is essential, IV) and that: if patient will accept ral and is nt psychtic, NICE recmmends ral lrazepam. Alternatively, if psychtic and taking ral, cnsider an antipsychtic (e.g. halperidl r lanzapine) in additin t ral lrazepam. if patient will nt accept ral (r, frm previus experience, this is cnsidered ineffective) cnsider IM lrazepam fr nn-psychtic patients. Alternatively, if psychtic and nt accepting ral, cnsider use f IM lrazepam in additin t IM antipsychtic (e.g. halperidl r lanzapine). IM Lrazepam and IM Olanzapine can nly be given cncurrently if a minimum f ne hur has elapsed between the tw agents (When using antipsychtics parenterally, ensure ready availability f parenteral prcyclidine. NICE als recmmends parenteral benztrpine, but this prduct has, since, been discntinued in the UK.)
