Abstract

Setting: 


     This study was conducted in Vicente Sotto Memorial Medical Center located at B. Rodriguez Street, Cebu City which is a tertiary level, government owned hospital with a 400 bed capacity.


Samples :


     The research sample are data of surgeries in patients with non-ruptured appendicitis as pre-operative diagnosis under spinal anesthesia as the anesthetic technique performed by the VSMMC anesthesia training residents last Jan 01-Dec 31, 2007. Data were collected from the anesthesia pink form records and operating room logbooks.


Main Outcome Measures:


     Data Collection Tool was used to gather all operative anesthesia records from Jan 01-Dec 31, 2007 who underwent appendectomy under spinal anesthesia ages 15-65 years old. Frequency and percentage of distribution utilized descriptive statistics. Chi-square test the differences using variables based as reported frequencies.


Results :


     The highest incidence of the patients who underwent appendectomy was within the age range of 15-35 years old (77%) and most of the cases were males (male n=304 vs. females n=164) (P = 0.438). The 3rd year anesthesia residents had the highest success rate in performing spinal anesthesia for non-ruptured appendicitis ages 15-65 years old. Bupivacaine 20 mg 0.5% Isobaric had the highest success rate among local anesthetics used for spinal anesthesia in appendectomy (P value =0.288). Out of 468 cases who underwent appendectomy from  January 01, 2007 to December 31, 2007, Bupivacaine 20 mg 0.5% Heavy had the highest failure rate 0.064% followed by Tetracaine 20 mg 0.056% and with Bupivacaine 20 mg 0.5% Isobaric 0%. (P=0.688).


Conclusion:


     The highest incidence of the patients who underwent appendectomy was within the age range of 15-35 years old and most of the cases were males. The 3rd year anesthesia residents had the highest success rate in performing spinal anesthesia for non-ruptured appendicitis ages 15-65 years old. Bupivacaine 20 mg 0.5% Isobaric had the highest success rate among local anaesthetics used for spinal anesthesia in appendectomy. Bupivacaine 20 mg 0.5% Heavy had the highest failure rate 0.64% who underwent appendectomy from January 01, 2007 to December 31, 2007.


 


 

Objectives

General Objectives:


   To determine the success rate of Tetracaine 20 mg, Bupivacaine 20 mg 0.5% Heavy, Bupivacaine 20 mg 0.5% Isobaric in spinal anesthesia, among patients 15-65 years old admitted at VSMMC for non-ruptured appendicitis CY Jan 01- Dec. 31, 2007.


Specific Objectives:


  1. To determine the clinical profile of patients in terms of 


      1.1 age interval


           a. 15-35 years old


           b. 36-60 years old


           c. >60 years old


      1.2 gender


   2. To determine which among the level of anesthesia residency has the highest success rate in performing spinal anesthesia in appendectomy among patients 15-65 years old?


      a) 1st year anesthesia residency


      b) 2nd year anesthesia residency


      c) 3rd year anesthesia residency


   3. To identify which local anesthetic is noted to have higher failure rate for an anesthetic procedure?


      a) Tetracaine 20 mg


      b) Bupivacaine 20 mg 0.5% Heavy


      c) Bupivacaine 20 mg 0.5% Isobaric
