Abstract
Introduction: Hearing loss after surgery is reported rarely. Its prevalence rate is different and reported to be between 3-92%. Hearing loss is often subclinical and not diagnosed without audiometry. The aim of this study was to determine rate of hearing changes after spinal anesthesia in patients undergoing surgery with spinal anesthesia.
Methods: In this descriptive study, forty male patients scheduled for repair of inguinal hernia under spinal anesthesia were selected by simple sampling method. Before surgery, audiometry was performed for both the ears of the patients. Audiomatery was performed again by the audiometry specialist on day one, five, fifteen and two months after surgery.
Results: Hearing loss was observed in 13 (32.5%) patients. Hearing loss in 12 patients (92%) was in low hearing frequency range and 1 patient (8%) was in mid hearing frequency. Hearing loss in 8 patients (61%) was ipsilateral and in 5 patients (39%) was bilateral. Hearing loss in 9 patients (69%) on 5th day and 2 patients (5/15%) on 15th day resolved spontaneously.
Conclusion: Results of this study conformed that hearing loss after spinal anesthesia is not a serious problem and can resolve spontaneously. It seems that there is relationship between hearing loss and headache.

Abstract
Introduction: Spinal anesthesia via Marcaine hyperbaric in different patients is associated with different side effects. The present study was performed to detect recovery period, Gastrointestinal and Respiratory side effects in spinal anesthesia with hyperbaric marcaine in diabetic and non diabetic patients.
Methods: In this comparative study, 62 patients (30 diabetic and 32 non-diabetics) with sub abdomen and lower organ surgeries were selected with simple sampling. After spinal anesthesia with hyper baric marcaine was done , recovery duration , Gastrointestina and respiratory side effects in two groups were evaluated . Data were collected using questionnaire, physical examination and patients’ records and were analyzed utilizing statistical, independent t –t, and fisher exact test.
Results: Gastrointestinal and respiratory side effects in two groups revealed no statistically significant difference (P>0.05). But the mean length of recovery residence showed a significant difference in the two groups of control and experiment (p=0.05) In fact, diabetic patients recovery duration was shorter.
Conclusion: Since Gastrointestina and respiratory side effects were same in the two groups and also recovery period was shorter, its appears that hyperbaric marcaine in spinal anesthesia is apppropriate for diabetic patients.

Abstract
Introduction: Spinal anesthesia in opium-addicted patients can be associated with many complications. Hence, this study aimed to investigate sensory and motor block characteristics, duration of postoperative analgesia, hemodynamic and side effects by adding Fentanyl to bupivacaine in spinal Anesthesia of opium-addicted patients.
Methods: In a double-blind randomized clinical trial, 60 American society of Anesthesiology (ASA) class I and II opium-addicted patients under spinal anesthesia in lower abdominal and lower limb operations were randomly classified into two groups of spinal anesthesia with bupivacaine and bupivacaine-fentanyl. Clinical symptoms, side effects, the duration of sensory and motor block, initiation of analgesia requirement and sensory block were assessed.
Results: The study results indicated no significant difference between bupivacaine and bupivacaine-fentanyl groups in regard with demographic, side effects, blood pressure and heart rate, though a significant difference was observed in respiratory rate 5min, 10min, 45min, 75min and 90 min after block. Duration of sensory (100.33 to 138.83) and motor block (93.43 to 107.66) and , initiation of analgesia requirement (165.33 to 187.76) was significantly longer in bupivacaine-fentanyl, though initiation of sensory block (8.83 to 4.93) was significantly longer in bupivacaine.
Conclusion: Addition of fentanyl to bupivacaine in spinal anesthesia increases the duration of sensory and motor block and initiation of analgesia requirement in opium-addicted patients and also decreases initiation of sensory block in these patients.
