We compared the analgesic effect of bupivacaine infiltration into surgical wounds with that of epidural block after laparoscopic cholecystectomy (LC). Forty-five patients (ASA physical status I-II) for LC were randomized into three groups (n = 15 in each group). Patients received only general anesthesia (Group C), received infiltration of 0.5% bupivacaine into the surgical wound before surgery combined with general anesthesia (Group L), or received epidural anesthesia combined with general anesthesia (Group E). Postoperative pain was assessed using visual analogue scale (scale: 0-10) at 1, 2, 6 and 12 hours after the operation, the need for additional supplemental analgesics, and the cost of anesthesia. Visual analogue scale in Group C at 1, 2, or 6 hours was significantly greater than that of Group L and E. The number of patients who needed supplemental analgesics was 9 in Group C, 5 in Group L, and 2 in Group E. The cost of pharmaceutical and anesthetic practice of Group E was more expensive than Group L and C. In conclusion, infiltration of bupivacaine combined with general anesthesia is an effective and economical method of postoperative pain relief.

This prospective, randomized, double-blind study compared the analgesic efficacy of oral diclofenac resinate 0.5 mg.kg(-1) with paracetamol 15 mg/kg(-1) for control of postoperative pain in paediatric patients for outpatient bilateral myringotomy and tube insertion. Paracetamol, the most commonly used oral analgesic for paediatric patients, was compared with a new palatable syrup formulation of diclofenac. Sixty-three ASA 1 orA SA 2 children aged one year and above were randomly assigned to receive diclofenac (Group A) or paracetamol (Group B). The study drug was given 30 to 60 minutes before induction of anaesthesia. Anaesthesia was induced with either inhalational sevoflurane or intravenous thiopentone. All subjects received intravenous fentanyl 1 microg/kg(-1) intraoperatively. Postoperative pain was assessed by a blinded observer using the CHEOPS score on eye-opening, and then at 10, 30 and 60 minutes. Children with a CHEOPS score > 7 received further fentanyl 1 microg x kg(-1). The number of cases requiring this "rescue" analgesia was recorded. Both groups were comparable in demographics, induction technique, duration of anaesthesia and time between premedication and induction of anaesthesia. Overall, CHEOPS scores were low for both groups at all times and did not differ between the groups at any time. Twenty per cent of the diclofenac group and 27% of the paracetamol group required rescue analgesia (not statistically significant). The efficacy of diclofenac 0.5 mg x kg(-1) and paracetamol 15 mg x kg(-1) as oral analgesic premedication for BMT was comparable in children receiving an anaesthetic which included intraoperative administration of fentanyl 1 microg x kg(-1).

Postoperative pain relief is a growing concern to an anaesthesiologist since no single analgesic is free from side-effects. Moreover, it becomes a challenge after caesarean section delivery to provide postoperative pain relief without much sedation, respiratory depression or problems like nausea, vomiting, so that early baby acceptance and care by mother is promoted. Antinociceptive effect of midazolam is well established by now and its safety is documented. This observation was made in a blind randomised study of 40 women of ASA I/II to evaluate postoperative pain relief using intrathecal midazolam in caesarean section delivery. Group A patients (n=20) received 1.5 ml of 5% lignocaine only and group B patients (n=20) received mixture of 1.5 ml 5% lignocaine with 2 mg midazolam (preservative free) through intrathecal route at L3.4 interspace; vital parameters were monitored intra-operatively and postoperatively and Apgar score of baby in 1st and 5th minute of deliverywas assessed. It was observed intrathecal midazolam produced highly significant (p<0.001) postoperative pain relief together with anti-emetic effect and tranquillity of patients of caesarean section delivery.

In a double blind, placebo-controlled trial, we have assessed the effects of pre-operative anxiolysis on postoperative pain scores in 112 ASA I-II women, aged 18-65 years, scheduled to undergo total abdominal hysterectomy. Subjects were randomly allocated to receive either oral diazepam 10 mg (n=56) or placebo (n=56) pre-operatively. Postoperative anxiety, pain scores, analgesic consumption, and sedation were evaluated at several time points during the first 24 h following surgery. Postoperative pain scores were found to be significantly higher in the diazepam group. Trait and state anxiety showed a significant effect on pain scores, independent of the treatment group. No difference was found between the groups in morphine consumption, but there was a significant reduction in morphine consumption with time.

Postoperative pain after total knee arthroplasty (TKA) is severe, and achieving adequate analgesia remains a clinical challenge. We tested the hypothesis that, in patients having unilateral TKA under intrathecal (IT) anesthesia, the addition of a femoral nerve block would provide superior analgesia when compared with IT morphine and demonstrate fewer adverse side effects. In a single-blinded and controlled trial, 41 ASA I-III patients undergoing unilateral TKA were randomized into 2 groups. Both groups received 15 mg of IT hyperbaric bupivacaine for the surgical anesthetic. Group ITM received 250 microg of IT morphine and group FNB received an ultrasound-assisted femoral nerve block with 40 mL of 0.5% ropivacaine, 5 microg/mL of epinephrine, and 75 microg of clonidine. At 1, 2, 4, 6, 12, and 24 h postoperatively, we measured visual analog scales for pain, cumulative IV morphine consumption, hemodynamics, and side effects. There were no statistically significant differences in morphine consumption, pain at rest, or pain with movement. However, group FNB had fewer perioperative side effects including nausea, vomiting, and pruritus (P < 0.05 for each event). This corresponded to a decrease in patient satisfaction in group ITM, in which 20% of the patients rated their experience as "unsatisfactory" (P < 0.05). We conclude that, in comparison with IT morphine, a single injection femoral nerve block provides equivalent analgesia but with a significant reduction in side effects for patients having TKA under bupivacaine intrathecal anesthesia.

The efficacy of scalp nerve block using 0.5% bupivacaine with adrenaline for postoperative pain relief in craniotomy patients was evaluated in 40 ASA I or II adult patients undergoing supratentorial craniotomy. A standard general anaesthesia technique was followed. Patients were randomly divided into two groups. Group B received 0.5% bupivacaine with 1:400,000 adrenaline and group S received normal saline with 1:400,000 adrenaline, both after skin closure. Postoperative pain was assessed at 30 seconds and 1, 2, 4, 6, 8 and 12 hours using a numerical rating scale. Diclofenac IM was administered as rescue analgesia if patients reported a numerical rating scale of 40 or more. Tramadol IV was administered as second rescue analgesia. Sixty per cent of patients in group S experienced moderate to severe pain (numerical rating scale of 40 or more) at some time during the first 12 postoperative hours in comparison to 25% patients in group B. Median pain scores were significantly lower in group B for up to 6 hours. Significantly more patients were pain free up to four hours in group B. Median duration for the requirement of first dose of diclofenac was longer in group B compared to group S (360 min vs 30 min, P < 0.01). The number of doses of diclofenac (5 vs 19) was significantly lower in group B compared to group S (P < 0.01). Tramadol was required by six patients in group S only. Scalp nerve block using 0.5% bupivacaine with 1:400,000 adrenaline decreases the incidence and severity of postoperative pain in patients undergoing supratentorial craniotomy.

The purpose of the present study was to determine the postoperative analgesic effects of lornoxicam and the reduction in tramadol consumption. Fourty patients of ASA class I-II, 18-70 years of age, undergoing thyroidectomy were assigned in a randomized manner into two groups: GroupL received 8 mg of lornoxicam i.v. at the end of the operation followed by 8 mg of lornoxicam b.i.d., i.v. for 24 hours postoperatively. GroupP received 4 ml of saline solution i.v. at the end of the operation and the same amount b.i.d., i.v. for 24 hours postoperatively. The requirements for supplemental analgesics were recorded at 0-6, 6-12 and 12-24 hour intervals. Postoperative pain scores were evaluated at 15th min. and 1, 2, 4, 6, 8, 12, 18 and 24th hours using Visual Analogue Scale (VAS). The time to first analgesic requirement was significantly longer in GroupL compared to GroupP (101.7 vs 37.9 min, p<0.001). Pain scores were significantly lower in GroupL compared to GroupP at 15th min, 1, 8 ,12 and 18th hours. Twenty four hour analgesic consumption was significantly lower in GroupL compared to GroupP (p<0.05). The amount of tramadol consumed in GroupL was 60% lower compared to GroupP (100 mg and 250 mg (mean), respectively). 100% of the patients in GroupL and 60 % of the patients in GroupP needed supplemental analgesics. The degree of satisfaction with postoperative pain management was excellent in 95 % of patients in GroupL and 25 % of patients in GroupP. Eighteen patients in GroupP and 9 patients in GroupL had nausea (p=0.002), and fifteen patients in GroupP and 8 patients in GroupL had vomiting (p=0.025). Lornoxicam decreased the opioid need, the incidence of nausea and vomiting and postoperative pain scores. Moreover, it was observed that the time needed for the first analgesic requirement was prolonged following thyroidectomies.

Postoperative pain after laparoscopic cholecystectomy is an ongoing problem. To relieve this pain, practitioners have used many anesthetic and analgesic drugs. This study was undertaken to assess the effects of incisional and intraperitoneal administration of ropivacaine on postoperative pain and stress response in patients undergoing laparoscopic cholecystectomy. In this prospective, single-blinded, randomized study, 45 patients with ASA (American Society of Anesthesiologists) scores I and II who were about to undergo laparoscopic cholecystectomy were divided into 3 groups. After cholecystectomy, a total of 40 mL of 3.75% ropivacaine was administered pre-incisionally and intraperitoneally to patients in group 1 (n=14); pre-incisionally and intraperitoneally to patients in group 2 (n=17); and intraperitoneally and locally at incision sites to patients in group 3 (n=14). Blood levels of epinephrine and norepinephrine were examined preoperatively, 15 min after insufflation, and at the end of the operation. Visual analog pain scale scores and analgesic requirements were used for 24-h postoperative follow-up of pain levels reported by patients. No statistically significant difference was found among the 3 groups with respect to visual analog pain scale scores, total analgesic requirements, and accompanying pain, nausea, and vomiting. The earliest analgesic requirements were seen in group 2 (P<.005), and less shoulder pain was noted in group 3 (P<.005). Norepinephrine and epinephrine levels showed no statistically significant differences between the 3 groups. Administration of ropivacaine preoperatively and postoperatively for laparoscopic cholecystectomy has similar effects on postoperative pain and the stress response of patients.

The aim of the study is to evaluate the efficacy of post-incisional wound infiltration with levobupivacaine in preventing the postoperative pain associated with inguinal hernia repair in children. Thirty boys, ASA I - II, aged 2 - 12 yrs., undergoing unilateral inguinal hernioplasty under general anaesthesia as day-case patients were allocated randomly to have postoperative analgesia either with post-incisional wound infiltration with levobupivacaine 1.25 mg/kg or with paracetamol 30 mg/kg administered rectally. Postoperative pain was assessed initially in the Post-Anaesthesia Care Unit and on the ward by an observer and afterwards for the next 24 h by the parents, using the Poker Chip Tool for preschoolers and the Visual Analogue Scale for older children, respectively. Postoperative pain was managed by giving paracetamol. The duration of the postoperative analgesia was estimated based on the time when rescue analgesia was first given. Assessment of the quality of postoperative analgesia was based on the children's behaviour. The wound infiltration group showed an increased duration of postoperative analgesia (p < 0.001) and early mobilisation, while the efficacy of postoperative analgesia tended to be more adequate, although no statistically significant difference was noted.

Extended spinal anaesthesia using a spinal micro-catheter was used as a primary method of anaesthesia for elective colorectal cancer surgery in 68 high risk patients over a 14-year period in our institution. The technique was also useful in eight elective and 13 emergency abdominal surgeries. All patients suffered from severe chronic obstructive airway disease requiring multiple inhalers and drugs (ASA III). Thirty nine of these patients also suffered from angina, myocardial infarction, diabetes and other systemic diseases (ASA IV). Surgery included right hemicolectomy, left hemicolectomy, total colectomy, sigmoid colectomy, Hartman's resection, anterior resection of rectum, abdominoperineal resection, cholecystectomy (open and laparoscopic) and obstructed inguinal hernia requiring laparotomy. Spinal anaesthesia was performed under strict aseptic conditions with a 22 gauge spinal needle with a mixture consisting of 2.75ml of 0.5% heavy bupivacaine and 0.25ml of fentanyl (25microg). This was followed by placement of a spinal micro-catheter and the duration of anaesthesia was extended by intermittent injection of 0.5% isobaric bupivacaine. Brief hypotension occurred in 12.4% of patients during the establishment of anaesthetic block height to T6-7 and was duly treated with intravenous administration of fluid and ephedrine hydrochloride. Good anaesthesia resulted in all patients except for brief discomfort in some patients during hemicolectomy surgery possibly due to the dissection and traction on the peritoneum causing irritation to the diaphragm. The use of sedation was avoided. General anaesthesia was administered in one patient and this patient required postoperative ventilation and cardiovascular support in the Intensive Care Unit. The spinal micro-catheter was removed at the end of surgery. Postoperative pain relief was obtained by administering intravenous morphine through a patient controlled analgesia machine in the critical care ward area (High Dependency Unit). There was a low incidence of minor postoperative side effects such as nausea (14.6%), vomiting (7.9%), minor post dural puncture headache (5.6%) and pruritus (5.6%). We conclude that spinal anaesthesia with a micro-catheter may be used as a primary method of anaesthesia for colorectal cancer surgery and other major abdominal surgery in high-risk patients for whom general anaesthesia would be associated with higher morbidity and mortality.
