“…So in our study, we were able to obtain unilateral sensory blockade, 98.33% in Group B and 95% in Group BF patients. These observations are consistent with the findings of Barghi et al 11 Hence we can conclude that lower doses of bupivacaine without fentanyl lead to more unilateral distribution of sensory and motor block when needle gauge, speed of injection and lateral decubitus position time kept constant. In our study, none of the patients of either group had inadequate analgesia or required general anaesthesia for failed block that are similar to the results by Barghi et al and Singh et al…”

“…[7][8][9][10][11][12][13][14][15] Low dose local anesthetic solutions by using a pencilpoint needle and slow intrathecal injection have been reported to obtain satisfactory unilateral spinal anesthesia (USpA), which should also minimize the cardiovascular effects of spinal block. 13,[16][17][18][19] With addition of lipophilic opioid to local anaesthetic, it is possible to improve the quality of anaesthesia even when low dose bupivacaine is administered.…”

“…Since the duration of the local anesthesia is dependent on the dose administered, 1,3,18 lower doses of bupivacaine in spinal anesthesia have also been examined with unsatisfactory results for routine daycase use. 17,[19][20][21][22] Chloroprocaine is particularly well suited to ambulatory neuraxial anesthesia, producing a fast onset excellent sensory block. 23,24 However in the early 1980s, neurological deficits were observed after apparent intrathecal injection of a chloroprocaine solution containing sodium bisulfite intended for epidural administration.…”

“…In studies using hyperbaric bupivacaine, it was advised to give lateral position to the patient on the operation side approximately for 10-20 minutes to establish efficient unilateral spinal block (18,19). In our study, the patients were turned to lateral position on the operation side for 15 minutes and intratechal injection time was about 40 seconds.…”

Abs tractAim: Spinal anesthesia is frequently used for procedures involving the lower limbs. Compared with general anesthesia, low-dose spinal anesthesia is a cost-effective method and has advantages such as avoiding hypotension, longer duration of anesthesia and increased length of hospitalization. The aim of this trial was to compare two different low-dose bupivacaine drug regimens. Methods: Sixty unpremedicated patients were randomly allocated into two groups (n=30). There were no differences between the groups in age, weight, the American Society of Anesthesiologists (ASA) physical status classification, gender, and duration of surgery. We performed spinal anesthesia at the L3-4 interspace with the patient in the lateral decubitus position. We administered 6.5 mg (group 1) and 8 mg (group 2) 0.5% heavy bupivacaine into the subarachnoid space. We positioned the patient laterally to the operation side for 15 minutes, then, turned to supine position. Motor and sensory block was assessed by the Bromage scale and pinprick test. Results: There were significant differences between the two groups in duration of motor block, but no significant differences in hemodynamic response to spinal anesthesia. None of the patients had intraoperative pain. Five patients in group 1 and 2 patients in group 2 had urinary retention. Conclusion ÖzetAmaç: Spinal anestezi sıklıkla alt ekstremite operasyonları için kullanılmaktadır. Düşük doz spinal anestezi genel anesteziye göre daha ekonomik bir metot olup, hipotansiyon, anestezinin uzun sürmesi, hastanede uzun süreli yatış gibi durumlardan kaçınılması gibi avantajlara sahiptir. Bu çalışmanın amacı 2 farklı düşük doz bupivakaini karşılaştırmaktır.Yöntemler: Premedikasyon yapılmamış 60 hasta randomize olarak 2 gruba ayrıldı. Gruplar arasında yaş, ağırlık, ASA grubu, cinsiyet, ameliyat süreleri bakımından farklılık yoktu. Spinal anestezi L3-L4 aralığından lateral dekübit pozisyonda yapıldı. Grup 1'e 6.5 mg, grup 2'ye 8 mg %0.5 ağır bupivakain subaraknoid aralıktan verildi. Hastalar operasyon yapılacak tarafta 15 dakika bekletildikten sonra sırtüstü pozisyona çevrildi. Motor blok Bromage, duysal blok Pinprick testi ile değerlendirildi. Bulgular: İki grup arasında motor blok açısından anlamlı farklılık varken, spinal anesteziye hemodinamik cevap açısından anlamlı bir farklılık yoktu. Hiçbir hastada intraoperatif ağrı olmadı. Grup 1'de 5 hastada, Grup 2'de 2 hastada üriner retansiyon gelişti. Sonuç
