A Clinical Evaluation of the GemStar® and the AmbIT® Pumps for Patient-Controlled Epidural Analgesia
BACKGROUND Patient-controlled analgesia is used for both labor and postoperative analgesia. OBJECTIVES This study aimed to assess user satisfaction and functionality of two ambulatory, electronic patient controlled analgesia devices, the GemStar pump Hospira Inc., Illinois, USA) and the ambIT Ambulatory Infusion Therapy pump (Sorenson Medical Products, Utah, USA). PATIENTS AND METHODS It wa...
Abstract Aims and Background: New standards have been developed for pain management in the recent years, and many focused on perioperative pain management to reduce complications during and after the surgery. This study has been designed to determine the impact of ultrasonography on the onset and duration of the analgesia by femoral nerve block after isolated femoral fracture surgery. Ma...
BACKGROUND Epidural analgesia initiated early in labor (when the cervix is less than 4.0 cm dilated) has been associated with an increased risk of cesarean delivery. It is unclear, however, whether this increase in risk is due to the analgesia or is attributable to other factors. METHODS We conducted a randomized trial of 750 nulliparous women at term who were in spontaneous labor or had spon...
OBJECTIVE Since March 1992, intravenous nalbuphine hydrochloride has been used prehospital by paramedics in the Plymouth area. This study assesses the impact of this intervention. METHODS A prospective study of the parenteral analgesic requirements of 1000 consecutive patients arriving by ambulance at the accident and emergency (A&E) department of a large district general hospital. Where pare...
Potent opioids are excellent painkillers but their use is hampered by side-effects such as nausea, vomiting, bowel dysfunction, urinary retention, pruritus, sedation and respiratory depression. Co-analgesics are often combined with opioids to reduce the prevalence of these unwanted effects while maintaining or even improve the quality of analgesia. A search of the recent literature demonstrated...
SUMMARY The expectation of pain relief can exert a powerful analgesic effect, even when pain is severe. Depending on the nature of experiences and instructions provided, a placebo analgesic effect can be elicited acutely in a very large percentage of individuals, in both experimental and clinical contexts. Placebo analgesia has been linked with activity in the prefrontal cortex, endogenous opio...
In this study analgesia induced by different dosages of nicotine was examined on mice. Nicotine with different dosages (0.1, 0.01, 0.001 mg/kg) was injected by intraperitoneal manner. Formalin test was then performed after ten minutes. Nicotine caused both acute and chronic phase analgesia with all dosages. We used, but the most analgesic dose was 0.1 mg/kg. Theophyline is an adenosin receptor ...
Aims and Background : Patients undergoing abdominal surgery usually receive an epidural block for postoperative analgesia. However, when epidural analgesia is contraindicated or unwanted, various regional analgesia techniques are used in conjunction with systemic analgesia. The objective of this trial was to assess the effectiveness of paravertebral block in patients undergoing laparotomy. Mate...
abstract introduction: due to the increasing number of breast masses and a more precise attention to them, a greater number of patients refer to clinics for biopsy or resection of breast and axillary lymph nodes. an appropriate anesthesia method can decrease hospitalization time, its expenditure and postoperative complications. paravertebral anesthesia [1] is a simple and feasible method in mos...
background: spinal analgesia is one of the effective and rapid methods for labor. it is not commonly used because of short duration of analgesia and motor block, which limits mother's force in labor progression. we attempted to prolong duration and quality of analgesia by adding epinephrine. methods: in this quasi-experimental study 90 pregnant women gravid ii and iii who referred to motazedi a...
