Volume 61, Issue 4 (7-2003)
Abstract
The induction characteristic of halothane in nitrous oxide and oxygen were compared with halothane in oxygen alone and intravenous induction with thiopentum and succinylcholine.
Materials and Methods: A vital capacity technique was used for the gaseous induction groups using a mapleson F system and a 1-litre reservoir bag. four end points of anesthesia were recorded: time to cessation of hand grip, time to loss of eyelash reflex, time to jaw relaxation, and time to settled breathing after tracheal tube insertion .we also recorded sequential blood pressure and pulse rate , the incidence of adverse airway events and the acceptability of the induction technique .
Results: Induction with thiopentum and succinylcholine had a faster time to cessation of hand grip (p, 0.05) and jaw relaxation (p, 0.01). These differences disappeared with the final induction stage and halothane in nitrous oxide and oxygen had the faster time to regular settled breathing though this did not reach statistical significance. Cardiac stability was good and comparable in all groups.
Conclusion: These were few adverse airway events in any group and none caused oxygen saturation to fall below 96%. There was more excitation in the gaseous induction groups.

Abstract

Background: Total Intravenous Anesthesia (TIVA) compared to general anesthesia has some pits and falls. Many drugs have been employed for this anesthesia. Propofol is accounted as the last advent anesthetic drug. It belongs to alkyl phenol families and has been accounted one of the best choices for the continuous infusion. Invention of midazolam as the first water soluble benzodiazepine was also an important event in anesthesia and it can be used as continuous infusion for the anesthesia.

Materials and Methods: In this randomized controlled clinical trial, alfentanyl plus propofol or midazolam were used for TIVA anesthesia in 60 female patients undergoing Dilatation and Curettage (D&C) in Dr.Shariati hospital in March 2002 till March 2003. They were allocated reandomly in two group of alfentanyl plus propofol (propofol group) or alfentanyl plus midazolam (midazolam group)

Results: There was no significant difference in mean of age between propofol group and midazolam group (P>0.05), also There was no significant difference in preanesthesia condition such as blood pressure and heart rate between propofol group and midazolam group (p>0.05). After induction of anesthesia there was a gross blood pressure decrease in both group that it was greater in midazolam group (85 mmHg versus 73 mmHg, P<0.05 ) following this, there was an increase in heart rate in both groups that it was modest in propofol group (98 Beat/Sec versus 118 Beat/Sec, P<0.05). There was no significant difference in mean infused alfentanyl (P>0.05) also there was just one naloxane injection in midazolam group that have no significant difference between groups (P>0.05). Recovery room stay was significantly lower in propofol group (25 minutes versus 39 minutes, P<0.05).

Conclusion: The results of this study was similar to Vuyk et.al.In their study there was a significant lower recovery time estimated by psychomotor reflexes and there was significant lower drowsiness, place and time orientation time compared to midazolam group. Finally according to the results of this study it can be resulted that TIVA with propofol is more suitable than midazolam and it can lower hospitalization time and cost. In future studies using other narcotics and other narcotics-anesthetic compounds with various dose can be mentioned.

Abstract
Background: Bier block is a reliable technique used in extremity surgeries. Typically, angiocatheters are palced in the distal portion of the extremity that is going to be operated. Although, it is not the case in every operation. Therefore, determining the effectiveness of the local anesthetic injection site on the quality of the upper-extremity block can be helpful.
Methods: In this double-blinded randomized clinical trial that took place in Kowsar Hospital (Sanandaj, Iran) at 2020, 60 patients after complete monitoring and sedation were assigned randomly into proximal bier block (32 in experimental) and distal bier block (28 in control) groups. 10ml/kg Ringer serum was prescribed for patients in both groups on the non-surgical hand. Depending on the patients’ placement in either group, an angiocatheter (22 or 24) was attached to the ante-cubital area (proximal bier block group) or on the back of the patient's hand (distal bier block group). Respectively, after blood was drained by a Smarch band from the extremity that was to be operated, the tourniquet was inflated up to 150mmHg above the patient’s systolic pressure and the smarch band is untied from the hand. For every patient regarding the group they were assigned, 3mg/kg lidocaine 0.5% was administered through an angiocatheter. After 5 minutes, the depth of patient's anesthesia and pain intensity were measured. Sensory and motor recovery was assessed every 10 minutes after surgery. Patient satisfaction with anesthesia was measured after the surgery and characterized by excellent, good, moderate (pain relief), and unsuccessful (need for pain medications) indicators. In case insufficient depth was reached, intravenous Remifentanil was injected.
Results: According to the results of the chi-squared test, there were no significant differences in gender distribution (p=0.063), anesthesia class type (p=0.964), type of surgery (p=0.694), anesthesia satisfaction (p=0.578), sensory block of hand (p=0.529), motor block of hand (p=0.059), pain intensity (p= 0.634), pain relief medication requesting (p=0.755) and also body mass index (T-test used P=0.099) variables comparing both groups together. Additionally; according to the T-test results no significant differences were reported in the mean systolic pressure, mean diastolic pressure and mean heart rate variable in designated times.
Conclusion: There is no significant difference between the two groups. Therefore, using a distal Bier block can be an alternative if needed.
