Ischiorectal Block with Bupivacaine for Post Hemorrhoidectomy Pain
Rajabi, Mehdi,Hosseinpour, Mehrdad,Jalalvand, Faranak,Afshar, Mohammad,Moosavi, Golamabbas,Behdad, Samin The Korean Pain Society 2012 The Korean Journal of Pain Vol.25 No.2
Background: Hemorrhoid is one of the most common surgical diseases occurring in the anorectal region. In this study, we evaluated the effect of ischiorectal fossa block on alleviating post hemorrhoidectomy pain. Methods: In this study, 90 patients suffering from hemorrhoids were evaluated. They were randomly divided into 3 groups. The first group had no block, the second group an ischiorectal block with placebo (normal saline), and the third group a preemptive ischiorectal block with bupivacaine. Postoperative variables such as pain intensity, pethidine consumption, nausea, and vomiting were compared between the groups. Results: The postoperative pain score in group 1 was $8.5{\pm}1.3$ and $8.1{\pm}0.9$ (P=NS) in group 2. The post operative analgesic demand was $3.1{\pm}1.5$ and $3.3{\pm}1.8$ hours in groups 1 and 2, respectively (P=NS). The post operative pain score and analgesic demand were $4.2{\pm}2.1$ and $9.3{\pm}2.7$ hours, respectively, in group 3 (P < 0.0001). Conclusions: Preemptive ischiorectal block reduces the posthemorrhoidectomy pain and opioid demand.

소염제 piroxicam (PX, 4-hydroxy-2-methyl-N-2-pridyl-2H-1, 2-benzothiazine-3-carboxadiamide-1,1-dioxide)의 착물형성을 전이금속이온, Co(II), Ni(II), Cu(II), Zn(II)과 함께 메탄올(MeOH)/물 이성분 혼합물에서 25$^{\circ}C$, 일정한 pH=5.0와 I=0.1 M에서 분광광도법으로 연구하였다. 컴퓨터 프로그램 SQUAD를 스팩트라 데이터로부터 원하는 정보를 얻는데 사용하였다. Fitting 과정의 output은 안정도 상수, 평가한 안정도 상수의 표준편차, 농도분포 다아그램, 모든 종의 스팩트럼 프로파일이다. Co(II), Ni(II), Cu(II), Zn(II)의 PX 착체의 안정도 순서는 Cu(II) > Co(II) > Ni(II) ${\approx}$ Zn(II) 순서이다. 이것은 이들 금속이 온들이 기하학적 경향이 다른 이유일 것이다. PX의 산성도 상수는 다른 pH 값에서 흡수 스펙트럼으로 부터 위의 조건에서 역시 결정하였다. 컴퓨터 프로그램 DATAN을 PX의 산성도 상수의 결정하는 데 사용하였다. 산성도 상수의 validity는 잘 알려진 컴퓨터 프로그램 SPECFIT/32을 사용하였다. 안정 및 산성도 상수의 용매성질, 음이온과 같은 다른 인자의 효과에 관하여 자세하게 논의하였다. The complex formation of anti-inflamatory drug piroxicam (PX, 4-hydroxy-2-methyl-N-2--pridyl-2H-1,2-benzothiazine-3-carboxadiamide-1,1-dioxide) with transition metal ions Co(II), Ni(II), Cu(II) and Zn(II) in methanol(MeOH)/water binary mixtures were studied by spectrophotometric method at 25$^{\circ}C$, constant pH = 5.0 and I = 0.1 M. The computer program SQUAD was used to extract the desired information from the spectral data. The outputs of the fitting processes were stability constants, standard deviations of the estimated stability constants, concentration distribution diagrams and spectral profiles of all species. The sequence of the stability constants of PX complexes with Co(II), Ni(II), Cu(II) and Zn(II) follow the Cu(II) > Co(II) > Ni(II) ${\approx}$ Zn(II) order. This may be due to different geometry tendencies of these metal ions. The acidity constants of the PX were also determined under above condition from its absorption spectra at different pH values. The computer program DATAN was used for determination of acidity constants of PX. The validity of the obtained acidity constants was checked by a well known computer program SPECFIT/32. The effects of the different parameters like solvent nature, cations characteristics on the stability and acidity constants were thoroughly discussed.
