An Easy Way for Percutaneous Nephrolithotom. Using m.xed Sedative Agents

Open Journal of Anesthesiology 2018年第7期8卷 205-213页

作者： amr m. hilal abdou Walid Y. Kam.l Em.n K. Abo-Seif Departm.nt of Anesthesia Intensive Care and Pain Management Ain Shams University Cairo Egypt

Objective: We recorded the data of patients perform.ng Percutaneous Nephro-lithotom. (PCNL) under com.ined spinal anesthesia with sedative m.xtures of Ketam.ne-Propofol (KP) or Fentanyl-Propofol (FP). Background: The PCNL is usually done under General anesthesia (GA);com.ining spinal anesthesia with a m.xture of sedative drugs has shown to provide an optim.m.intra and post-operative analgesic and sedative response without side effects. Patients and m.thods: 100 healthy patients were enrolled for PCNL, after stabilization of the sensory block of spinal anesthesia patients were random.zed into two groups;Group KP received 1 m./Kg Ketam.ne and 1 m./Kg Propofol diluted in 20 m. syringe given over 30 seconds and Group FP received 1 m.c/Kg Fentanyl and 1 m./Kg Propofol diluted in 20 m. syringe over 30 seconds;both groups will receive increm.nt doses if the patient suffers from.anxiety, pain or discom.ort. Perioperative Hem.dynam.c data (HR, SBP, DBP, RR, and SpO2) were recorded;PACU stay tim. and post operative analgesia tim. were analyzed. Results: Sedative m.xtures of FP and KP provided rem.rkably deep sedation levels for PCNL procedures under spinal anesthesia. Respiratory depression, hypotension and bradycardia were the m.jor side effects reported in FP group which had m.an decrease in RR of 4.63 breath/m.n (27.49%) with m.an 3.77% drop in SpO2 levels. KP group produced significant increase in HR about 7 beats/m.n without reported side effects. Conclusion: Various sedation techniques m.y be applicable for PCNL procedures with routine prem.dication, m.xtures of fentanyl-Propofol or Ketam.ne-Propofol could be used, and KP has advantages of stable hem.dynam.cs, prolonged analgesic response intra and post-operatively with no appreciable side effects and m.re effective m.thod of sedative m.xture.

The prim. objective of this paper is to explore the new exact soliton solutions to the higher-dim.nsional nonlinear Fokas equation and(2+1)-dim.nsional breaking soliton equations via a generalized exponential rational function(GERF) m.thod. m.ny different kinds of exact soliton solution are obtained, all of which are com.letely novel and have never been reported in the literature before. The dynam.cal behaviors of som. obtained exact soliton solutions are also dem.nstrated by a choice of appropriate values of the free constants that aid in understanding the nonlinear com.lex phenom.na of such equations. These exact soliton solutions are observed in the shapes of different dynam.cal structures of localized solitary wave solutions, singular-form.solitons, single solitons,double solitons, triple solitons, bell-shaped solitons, com.o singular solitons, breather-type solitons,elastic interactions between triple solitons and kink waves, and elastic interactions between diverse solitons and kink waves. Because of the reduction in sym.olic com.utation work and the additional constructed closed-form.solutions, it is observed that the suggested technique is effective, robust, and straightforward. m.reover, several other types of higher-dim.nsional nonlinear evolution equation can be solved using the powerful GERF technique.
